Rethinking Human and Machine Intelligence (version 3)

Rethinking Human and Machine Intelligence through Kant’s Incongruent Counterparts

 

Abstract

This paper proposes a metaphysical framework for distinguishing between human and machine intelligence. By drawing an analogy from Kant’s incongruent counterparts, it posits two identical deterministic worlds -- one comprising a human agent and the other comprising a machine agent. These agents exhibit different types of information processing mechanisms despite their apparent sameness in a causal sense. By postulating the distinctiveness of human over machine intelligence, this paper resolves what it refers to as “the vantage point problem” – namely, how to legitimize a determinist’s assertion of determinism by placing the determinist within the universe.

 

Keywords: determinism; incongruent counterparts; simulation; state description; counterfactuals

 

Introduction

This paper was motivated by asking questions about the concept of amor fati (or “love of fate”) (Nietzsche, 1990, p. 99). This philosophy of life has inspired many of Nietzsche’s readers seeking guidance in life. However, his advice seems to have certain inconsistencies. For instance, how can someone learn to embrace fate if everything in her life has been predetermined? If determinism is true, would it not be accurate to say that even an act of learning to love her fate was also predetermined? Was Nietzsche himself, perhaps, predestined to encourage his readers to love their fate?

When a determinist asserts that the universe is deterministic, this requires assuming a hypothetical vantage point from which to describe the universe. At first sight, it seems reasonable to say that such a vantage point should be located somewhere beyond the universe. For instance, Wittgenstein (1922) notes that “the philosophical I” is a “metaphysical subject” that is “not a part of the world” (p. 75). Determinism is a philosophical judgment imposed upon the world. Accordingly, the determinist’s reasoning mind may have to be separated from the world. However, the determinist herself is a part of the world. According to Danielsson (2023), since “[w]e cannot stand outside the world,” “we always look at the world from the only vantage point that exists: from within. (Chapter 1)”

The above peculiar relationship between the two (i.e., the determinist vs. universe) can cause confusion. The determinist is a finite being located within space and time. Then, how could she justify the significance of her assertion of determinism, which is a view that seems to require attainment of a God’s-eye perspective? This issue will be referred to as the “vantage point problem” in this paper. 

To address the problem, this paper proposes to discuss two different types of deterministic worlds by using Kant’s “incongruent counterparts” (hereinafter, “ICs”) as an analogy. Admittedly, the use of Kant’s ICs may seem far-fetched, since his original purpose was to resolve an absolute versus relational space controversy. However, this concept is used for analogical reasoning only; it is not meant to provide direct insights into the issue at hand. If readers patiently follow this paper’s arguments to the end, they will see how it establishes a plausible model that allows a determinist to validly claim our universe as deterministic while remaining a part of it.

 

1. The Incongruent Counterparts

Kant devised the concept of ICs to address the issue of absolute versus relational space (Kant, 1994, pp. 145-174). According to the theory of absolute space, even if the universe had only one body and nothing else, that body would still have a spatial background in which it could move (Asher, 1987, p. 447). However, the relational view of space denies the existence of absolute space and defines motion only in relation to other bodies.

Kant develops his argument by discussing the left hand and right hand. Specifically, the left hand observed from a perspective restricted to the property of the left hand would be no different from the right hand observed from a perspective restricted to the property of the right hand. However, their difference is apparent “when both are considered in relation to some appropriate third thing” (Remnant, 1963, p. 393). In other words, they are revealed to have different orientations from an external perspective embedded in absolute space.

However, the aim of this paper is to use the IC analogy as a speculative tool for discussing the nature of determinism in relation to human reasoning. To achieve this, by building upon Kant’s concept, this paper assumes a world where only a left hand exists (an “LH” world) and another world where only a right hand exists (an “RH” world). Specifically, it posits the following cases.

LH1: A right hand cannot enter into the LH world. Also, the right hand is inconceivable in the LH world.

LH2: A right hand can enter into the LH world, and if it does, it will be perceived no differently than the existing left hand.

RH1: A left hand cannot enter into the RH world. Nevertheless, its attributes can be hypothesized in the RH world.

RH2: A left hand can enter into the RH world. Also, the RH world can hypothesize the attributes of the left hand before such entry takes place.

These cases will be mentioned again for analogical reasoning in subsections 2.1 and 2.2

 

2. Deterministic Knowledge

This paper will use the following key definitions:

(1) Deterministic knowledge (D knowledge): A totality of facts associated with all the past, present, and future events in a deterministic world.

(2) Deterministic world: A world where events are deterministic. There is metaphysical significance in considering a case of providing D knowledge to a cognitive agent of this world.[1]

Definition (1) is similar to Carnap’s (1947) “one state-description” (he notes that this idea was inspired by Wittgenstein) (p. 10). Specifically, it “describes the actual state of the universe” and “contains all true atomic sentences and the negations of those which are false” (p. 10). However, Carnap primarily devised this concept in relation to a semantical system for linguistic analysis. Meanwhile, D knowledge relates to descriptions of a deterministic world. In this regard, these two notions are different. Nevertheless, following Carnap, we will assume that D knowledge is an entirety of atomic sentences that describe a deterministic world.

Definition (2) introduces a seemingly contradictory idea. If D knowledge were provided to the agent, it suggests that she could gain knowledge about her future. However, if she did attain such knowledge, the D knowledge would no longer be valid because it fails to describe one particular event: her attainment of the knowledge. To address this apparent contradiction, this paper will examine reception of D knowledge in a metaphysical sense only.[2]

Now let us define two deterministic worlds that are established as “ICs.”

(i) An original world like ours that comprises a human agent.

(ii) A simulated world that replicates every aspect of the original world and comprises a machine agent emulating the human agent in a causal manner.[3]

According to Schwartz (2012), determinism is the view “that [possible] worlds cannot be the same up to a point and then diverge” (p. 216). However, in our thought experiment, it is possible that the deterministic worlds (i) and (ii) are computationally identical up to a particular point and then diverge when D knowledge is provided to them. If one contends that the human mind cannot be fully reduced to an algorithm, it becomes necessary to assume that such a divergence is possible.

For further discussion, this paper will use concepts of computationalism to investigate the characteristics of information processing exhibited by both agents. According to Beraldo-de-Araújio, the essence of computation is “symbolic manipulation” and concerns “mapping function between two sets of symbols” (Polak & Krzanowski, 2019, p. 6). The human agent’s symbolic manipulation, for instance, may take place through neural activities in the brain. Meanwhile, the machine agent performs symbolic manipulation by processing machine-readable symbols. By slightly changing Beraldo-de-Araújio’s definitions on p.6, this paper defines computation as follows.

(a) A process is a function P: I → O such that its domain I is a set whose elements are called input events and its co-domain O is a set whose elements are called output events, while both I and O are subsets of a physical world. For all xI, y = P(x) (yO) is a corresponding output event.

(b) A computer is a function C: S → T from a set of input symbols S to a set of output symbols T, such that C(x̅) is outputted by computing x̅. (x̅ is a symbolic representation of x.) A process P: I → O is computational if P is generated by a computer C.

In the simulated world, we suppose that the mind is a “classical von Neumann computer” and that “its representation-bearers [are] data structures” (Frankish & Ramsey, 2012, pp. 31-32).[4] This world is intentionally designed to avoid being based on a “connectionist” model.[5] Specifically, it may not be feasible for the connectionist model to accurately emulate the human agent due to its highly stochastic nature.[6] Such a feature might hinder accurate realization of a scripted scenario. Although the classical model may be much less sophisticated, it can at least robustly emulate human behaviors in hindsight if all the relevant information is available.

2.1 Type 1

If the D knowledge specific to the simulated world were provided to its agent, the agent would process reception of the D knowledge simply as one of the existing potential input events. This suggests that the agent executes rigid processing, as it cannot process in any other way an input that it was not configured to receive. This world is trivially deterministic in that it is governed by a predefined type of D knowledge (i.e., Type 1) that dictates how things should occur.

Through the IC analogy, the simulated world can be physically characterized by “LH1.” Recall that a right hand cannot enter into an LH world. Similarly, D knowledge should not be provided to the simulated world in order to retain its status as a totality of descriptions of the world. Additionally, the simulated world can be metaphysically characterized by “LH2.” If a right hand does enter into the LH world, it will be perceived no differently than the existing left hand. Likewise, even if D knowledge is provided to the simulated world, its provision would not be identified by its agent as distinct from all the other existing potential input events.

See the following mappings.  

I = {x1, x2, …, xn}

O = {y1, y2, …, yn}        

Since this is a trivially deterministic world, only one of the input events from x1 to xn is to occur. The pairs other than the actual input-output pair serve to illustrate counterfactual cases. These cases are included in Type-1 D knowledge. Now suppose that reception of D knowledge occurs immediately before a particular event in the input event set does. Then:

xD = xk (xD is reduced to xk.)        1 ≤ k ≤ n

xD = Reception of D knowledge

yD = yk

yD = A response to reception of D knowledge

However, the above mappings are based on a non-stochastic model, which does not allow for indeterminacy. By supposing for now that the simulated world is indeterministic, we can establish the following mappings.

I = {x1, x2, …, xn}

O = {y1[1], …, y1[s1]}, {y2[1], …, y2[s2]}, …, {yn[1], …, yn[sn]}

xD = xk (xD is reduced to xk.)        1 ≤ k ≤ n

yD = One element from {yk[1], …, yk[sk]} (The probabilities assigned to these stochastic outcomes add up to 1.)

The above stochastic model is meant to show that, even in an indeterministic world, as long as the agent relies on rigid processing, its response to reception of the D knowledge could be nothing other than any one of the predefined output events.

To illustrate the triviality of the simulated world, let us consider a hypothetical scenario involving a clinical psychologist named “Millicent” (or simply “Millie”). She loves coffee but often hesitates whether to drink it. One morning, she decides to have a coffee anyway while watching a seminar video through a tablet device. In this case, suppose that there is a 60% chance that she will stop drinking her coffee if she happens to think that it will do her no good. The following event mappings are established for her in atomic-sentential form:

x1 = The seminar tires me.

x2 = The coffee does not convince me of insomnia.

x3 = The coffee convinces me of insomnia.

y1 = I stop watching.

y2 = I keep drinking.

y31 = I stop drinking.

y32 = I keep drinking.

However, since the world is deterministic, only a particular event such as x1 (which does not allow a stochastic outcome) would have been configured to occur. Meanwhile, in a metaphysical sense, it is possible to assume that specific descriptions in the D knowledge could be provided to her immediately before x1 happens. Suppose that her tablet displays not only the above mappings but also a short history of her activities in the morning and the events to unfold throughout the day. How would she respond?

From a humanistic perspective, there must be a distinct mental representation corresponding to the event of “I see the descriptions.” However, Millie’s rigid processing mechanism would only be able to interpret the sight of the display as one of x̅1 to x̅3. Recall that Millie’s mind follows the classical computer model whose representation-bearers are data structures. Since she only executes rigid processing, a bit structure corresponding to her symbolic representation of the event would most probably be translated to a particular bit structure corresponding to one of x̅1 to x̅3. Suppose that it is interpreted as x̅3. Then, her processing mechanism would output either one of y̅31 and y̅32. Given the 60% chance, it would probably output y̅31, which should be accompanied by y31. In other words, she would probably stop drinking her coffee in response to receiving the D knowledge.

2.2 Type 2

If the D knowledge specific to the original world were provided to its agent, the agent would process reception of the D knowledge as a different input event than all the other previous potential input events. This means that the agent’s processing mechanism exhibits emergent processing, as it can distinctly identify a particular input event that was not supposed to happen. This world is non-trivially deterministic. Using the IC analogy, it can be physically characterized by “RH1” and metaphysically by “RH2.” Further, it is possible (rather than necessary) that the D knowledge only reflects every physical event across time. Unlike Type 1, this type of D knowledge (namely, Type 2) does NOT include counterfactual cases. Also, this knowledge is compatible with the block universe theory.

In the block universe model, “[w]hether past, present or future, all events ‘lie frozen’ in the four-dimensional block, much like the scenes from a movie are fixed on the film roll” (Thyssen, 2020, p. 6). If one were to see the events of the universe like fixed scenes on a film roll from an omniscient viewpoint across time, she might be able to extrapolate to a certain extent counterfactual cases in relation to those events. However, the scenes themselves do not include such information. In that sense, Type-2 D knowledge only mirrors the physical events.

Meanwhile, we assume that emergence of a new output in response to D knowledge reception is necessary, considering that the agent’s processing mechanism is assumed to be governed by causality. However, the content of the new output may be deterministic or non-deterministic. This is highlighted by the question mark in the input-output mappings below. The pairs other than the actual input-output pair are provided as dummies whose contents are unknown (which means that the counterfactual cases are unknown). “xn+1” (i.e., reception of D knowledge) is enclosed in parentheses to indicate that it is only a latent event in a metaphysical sense.

I = {x1, x2, …, xn,(xn+1)}

O = {y1, y2, …, yn, (?)}  

xD = xn+1                          yD = ?   

If the Millie scenario happened in the original world, she might have been struck to the core and asked, “Am I living in a Matrix?” by emergently interpreting her reception of D knowledge.

2.3 Type 3

Despite its assertion that the past, present, and future all coexist, the block universe theory does not demand absolute causality. Polkinghorne (2007) notes that “[b]elievers in the block universe are not forced to commit themselves to a deterministic account of its causal structure” (p. 977). However, assume that the original world is thoroughly deterministic in a causal sense. Then, one can entertain the idea that its agent’s decision-making processes are strictly deterministic in a metaphysical as well as physical sense. Specifically, the agent should produce a new output (whose content is deterministic) in response to receiving D knowledge of Type 2. This hypothetical situation would generate a derivative version of D knowledge (namely, D’). Then, the agent should produce another output in response to receiving D’, thereby generating another derivative version of D knowledge (namely, D’’). To aid in understanding this somewhat complex scenario, let us go back to the Millie story. With regard to the Millie of the original world, D’ knowledge might state as follows:

“Millie responds to D knowledge. She speaks, “Am I living in a Matrix?”

D’’ knowledge might state:

“Millie responds to D’ knowledge. She speaks, ‘I might need to take some medication to calm my caffeine-induced paranoia. Or maybe this world that I’m living in was monstrously rigged, and I must somehow survive by figuring out how I first reacted to… I don’t know, but it seems like this situation that I’m in happened already once before, and I must figure out whatever this evil gadget had said in the first place. Let me think… Whatever action I take right now, was that also predetermined?’”

See the following formal mappings:

I = {x1, x2, …, xn, (xn+1), (xn+2), … }

O = {y1, y2, …, yn, (yn+1), (yn+2), …}

xD = xn+1                          yD = yn+1                         

xD’ = xn+2                             yD’ = yn+2

…                                    …        

The above mappings may develop indefinitely.[7] All these potentially infinite counterfactual cases are included in Type 3.[8] Further, it can be said that this type of knowledge is generated by an inherent configuration of the world.[9] For instance, Tegmark (2008) argues that it is “plausible that our universe could be simulated by quite a short computer program” (p. 18). Based on the idea that “our universe is mathematics” (p. 1), he maintains that its realization only requires storage of “all the 4-dimensional data” (i.e., all the “[encoded] properties of the mathematical structure that is our universe”) (p. 18). He states that a “complete description” of a mathematical structure is “a specification of the relations between the elements” of the mathematical structure (p. 18). As such, the 4-dimensional data primarily relate to the abstract realm of mathematics. If his argument is true, we would not need any type of D knowledge (consisting of verbal descriptions in atomic-sentential form) in order to simulate a universe. Rather, D knowledge would be a byproduct of the mathematical structure and its specification.

 

3. The Vantage Point Problem

This section explores how the “vantage point problem” stated in this paper’s introduction can be addressed by relying on the concept of D knowledge. Let us first look into two philosophical cases where this problem has not been properly addressed.

(1) Tegmark[10] (2008) asserts that “[t]here exists an external physical reality completely independent of us humans” and that “[o]ur external physical reality is a mathematical structure (p. 1). However, despite presenting convincing arguments, he still fails to address the vantage point problem. In footnote 3 on p. 5, he notices the problem of how a mathematician should derive, through (i) a mathematical structure alone, (ii) an empirical domain and (iii) “a set of correspondence rules which link parts of the mathematical structure with parts of the empirical domain.” He hints at a possibility of achieving this by introducing a “car” analogy. Specifically, “given an abstract but complete description of a car (essentially the locations of its atoms),” “someone” that wants “practical use of this car” might “be able to figure out how the car works and write her own manual” by “carefully examining the original description.” Put simply:

“Someone” Mathematician

Car Universe

Description of the car Mathematical structure of the universe

Practical use of the car Empirical domain of the universe

Knowledge of how the car works Correspondence rules linking the mathematical structure with the empirical domain

While the mathematician is a part of the universe, that “someone” is not a part of the car. Therefore, the car analogy fails. The analogy would have been more accurate if the “someone” had a complete description of both herself and the car.[11] Tegmark’s case is one instance illustrating a common mistake made by scientists as well as philosophers – namely, the confusion that arises from the vantage point problem.

(2) Dennett (2003) notes that "confusion [over determinism] arises when one tries to maintain two perspectives on the universe at once" (p. 93). One perspective is the "God's eye" perspective, and the other is the "engaged perspective of an agent within the universe.” His description of the former perspective coincides with the Parmenidean view of the universe. He adds that “[f]rom the timeless God's-eye perspective nothing ever changes," as "the whole history of the universe is laid out 'at once.'" Dennett appears to give equal weights to both perspectives but cautions against assuming them at the same time. He does not provide a philosophical scheme where both perspectives can coexist. Specifically, he does not reveal how it is possible for the agent within the universe to assert determinism from a provisional God’s-eye perspective.

The above two cases illustrate the ongoing struggle of scientists and philosophers to reconcile the discrepancy between a human agent making a declarative statement (i.e., a deterministic worldview) about the universe at large and the universe where the agent belongs. It is believed that this paper has resolved this issue to a certain extent. Unlike machines, human intelligence is capable of emergently processing -- to use a bit of an oxymoron -- even “otherworldly but comprehensible” knowledge (i.e., D knowledge). By definition, D knowledge is an entirety of verbal descriptions encompassing the whole universe. This type of knowledge is inherently inaccessible; therefore, it can be considered to exist in an “otherworldly” realm. Nevertheless, it is deemed “comprehensible” from the human agent’s perspective, as evidenced by its capacity to provide a non-trivial response to D knowledge. This has a metaphysical implication that the human agent could potentially view the universe from a vantage point situated in a realm beyond the universe despite actually being a part of the universe. However, for machine intelligence, D knowledge is neither “otherworldly” nor “comprehensible.” In fact, there is no type of information at all that can be genuinely comprehended by machine intelligence. This is illustrated through the triviality of responses it might generate with regard to D knowledge in subsection 2.1.

Further, the same level of triviality could be said to be exhibited by a hypothetical agent whose declaration of determinism should be assumed to be inseparable, in a pancomputational[12] sense, from all the other events of the world. Specifically, in a world without a qualitative distinction between the two (i.e., espousal of determinism and the other physical phenomena), the agent (possibly a machine agent) would have no motivation in the first place to assume a higher “vantage point” from which to view the world. Roughly speaking, in such a world, no scholarly debate on determinism would have any meaning. If our universe is to be depicted differently from that world, a determinist’s declaration of determinism should by necessity stand out by acquiring a particular metaphysical meaning amidst all the events of the universe. This is achieved by granting a privileged status to the determinist regardless of the truthfulness of her argument. She can be granted such a status because of her inherent capacity to comprehend D knowledge.

Finally, note that this peculiar dynamic between the determinist’s philosophical mind and the universe can be best described through a dialectic circle in Maybee (2020, Section 1). Before the determinist decides on the determinacy of the events of the universe, these events must first be placed within her scope of thoughts. In other words, they should become the objects of her speculative investigation. Then, as she declares determinism, she realizes that the entire process (from her investigation up to the declaration) is also part of the deterministic scenario of the universe. Subsequently, she concludes from a transient God’s-eye perspective that every time she declares determinism, this would have also been predetermined. In hindsight, she realizes that her conclusion was also predetermined.

The above process continues,[13] thereby generating the dialectic circle. It expands as the determinist’s mind and the objects/events of the universe continue to encircle each other in an alternating manner. This type of circle provides a more nuanced illustration than the image of “eye” of the “metaphysical subject” encapsulated within “the field of sight” in Wittgenstein (1922, p. 75), as well as a different image that one may newly draw by placing the eye outside the field of sight.

 

4. Conclusion

The main ideas of this paper can be outlined as follows.

(1) Deterministic knowledge

l  Type 1

n  Dictates the world.

n  Includes finite counterfactual cases.

l  Type 2

n  Reflects the world.

n  Includes no counterfactual cases.

l  Type 3

n  Is generated by the world.

n  Includes infinite counterfactual cases.

(2) Deterministic worlds

l  Trivially deterministic world

n  Its agent executes rigid processing.

l  Non-trivially deterministic world

n  Its agent executes emergent processing.

Based on the above conceptual scheme, this paper has sought to distinguish human from machine intelligence by allowing for hard determinism. In accordance with this scheme, it attempted to justify a determinist’s assertion of determinism by placing the determinist within the universe.

However, this paper may face several challenges from readers. First, one might point out that the paper relies only on metaphysical speculation and lacks empirical support. However, many philosophical ideas are inherently speculative, aiming to look beyond the realm of empirical science. Despite their purely speculative nature, they can meaningfully influence the empirical world. For instance, this paper’s framework can be taken as a normative model for human vs. machine intelligence. Under this model, we can imagine measuring the level of enhancement in a connectionist-based AI by studying its response to a history of its replica provided as a certain kind of “D knowledge.”

Second, one may argue that the “vantage point problem” is not really a problem. She may have no difficulty accepting the idea that a determinist can describe the universe from a viewpoint situated within the universe. She can conveniently appeal to the causality principle to support determinism. However, causality itself does not tell us very much about her particular status as an intellectual being. If she conflates herself with mindless machines in accordance with pancomputationalism, her concern for the truth of determinism becomes insignificant. Philosophical truths are dead issues to mechanical beings. What this paper has done is illustrate a subtle difference between human and machine intelligence by assuming that both adhere to causality.

Third, one could suggest that this paper seems to beg the question, by assuming from the beginning that the original and simulated worlds are already different. Indeed, this is a notable limitation of the paper. Nevertheless, the author believes that it provided one original instance of a logical possibility where machines fall short of human intelligence. The author would be satisfied if even a single reader finds intellectual stimulation in the paper’s argumentation.

This paper has additional limitations. The conception of D knowledge, for example, may be deemed questionable by quantum physicists. They argue that describing physical events through exact spatial/temporal coordinates on the quantum level is impossible in principle. Additionally, the paper cannot explain the phenomenon of qualia or a sense of agency and free will. These problems require further study.

[1] Vihvelin (2023) proposes “[leaving] open the metaphysical possibility of time travel to the past and backwards causation” (p. 1). This concept is philosophically worth considering, even though it is unlikely to materialize in reality. Note that her proposal implicitly involves the idea of providing D knowledge to an agent in the past.  

[2] We assume that the cognitive agent receives only a “small breadth” of D knowledge that is associated with the agent. The entirety of D knowledge would be too immense to be processed by any agent.

[3] Müller (2014) indicates that there can be two different physical processes P1 and P2 that perform the same computation C (p. 9). Similarly, the original and simulated worlds are computationally the same but ultimately different.

Rethinking Human and Machine Intelligence (version 2)

Rethinking Human and Machine Intelligence through Kant, Wittgenstein, and Godel

Abstract

This paper proposes a metaphysical framework for distinguishing between human and machine intelligence. By drawing an analogy from Kant’s incongruent counterparts, it posits two identical deterministic worlds -- one comprising a human agent and the other comprising a machine agent. These agents exhibit different types of information processing mechanisms despite their apparent sameness in a causal sense. By postulating the distinctiveness of human over machine intelligence, this paper resolves what it refers to as “the vantage point problem” – namely, how to define the determinist’s reasoning mind in relation to the universe where the determinist belongs.

 

Keywords: determinism; incongruent counterparts; simulation; state description; counterfactuals

 

Introduction

This paper was motivated by asking questions about the concept of amor fati (or “love of fate”) (Nietzsche, 1990, 99). This philosophy of life has inspired many of Nietzsche’s readers seeking guidance in life. However, his advice seems to have certain inconsistencies. For instance, how can someone learn to embrace fate if everything in her life has been predetermined? If determinism is true, would it not be accurate to say that even an act of learning to love her fate was also predetermined? Was Nietzsche himself, perhaps, predestined to encourage his readers to love their fate?

When determinists assert that the universe is deterministic, this requires assuming a hypothetical vantage point from which to describe the universe. However, that vantage point should not belong in the universe.[1] Meanwhile, the determinists themselves are part of the universe. This peculiar relationship between the two appears to cause a contradiction. Therefore, they must figure out how to justify the significance of their assertion by situating themselves within the universe. This issue will be referred to as the “vantage point problem” in this paper.  

To address the problem, this paper proposes to discuss two different types of deterministic worlds by using Kant’s “incongruent counterparts” (hereinafter, “ICs”) as an analogy. The paper also builds upon Gödel’s proof strategy for his incompleteness theorem and Wittgenstein’s (1922) proposition that “the world is the totality of facts” (p. 25). Admittedly, the use of Kant’s ICs may seem far-fetched, since his original purpose was to resolve an absolute versus relational space controversy. In addition, Gödel’s theorem belongs in the field of mathematics, so one may question this paper’s approach for its potentially pseudo-philosophical utilization of the theorem. However, these concepts are used for analogical reasoning only; they are not meant to provide direct insights into the issue at hand. If readers patiently follow this paper’s arguments to the end, they will see how it establishes a plausible model allowing determinists to validly claim our universe as deterministic while remaining part of it.

 

1. The Incongruent Counterparts

Kant devised the concept of ICs to address the issue of absolute versus relational space (Kant, 1994, pp. 145-174). According to the theory of absolute space, even if the universe had only one body and nothing else, that body would still have a spatial background in which it could move (Asher, 1987, p. 447). However, the relational view of space denies the existence of absolute space and defines motion only in relation to other bodies.

Kant develops his argument by discussing the left hand and right hand. Specifically, the left hand observed from a perspective restricted to the property of the left hand would be no different from the right hand observed from a perspective restricted to the property of the right hand. However, their difference is apparent “when both are considered in relation to some appropriate third thing” (Remnant, 1963, p. 393). In other words, they are revealed to have different orientations from an external perspective embedded in absolute space.

However, the aim of this paper is to use the IC analogy as a speculative tool for discussing the nature of determinism in relation to human reasoning. To achieve this, by building upon Kant’s concept, this paper assumes a world where only a left hand exists (an “LH” world) and another world where only a right hand exists (an “RH” world). Specifically, it posits the following cases.

LH1: A right hand cannot enter into an LH world. Also, the right hand is inconceivable in the LH world.

LH2: A right hand can enter into an LH world, and if it does, it will be perceived no differently than the existing left hand.

RH1: A left hand cannot enter into an RH world. Nevertheless, its attributes can be hypothesized in the RH world.

RH2: A left hand can enter into an RH world. Also, the RH world can hypothesize the attributes of the left hand before such entry takes place.

 

2. Deterministic Knowledge

This paper will use the following key definitions:

(1) Deterministic knowledge (D knowledge): A totality of facts associated with all the past, present, and future events in a deterministic world.

(2) Metaphysically open deterministic world: A deterministic world where there is a metaphysical sense in assuming a scenario in which its deterministic knowledge is provided to a cognitive agent of the world.[2]

The concept of D knowledge is similar to Carnap’s (1947) “one state-description” (he notes that this idea was inspired by Wittgenstein) (p. 10). Specifically, it “describes the actual state of the universe” and “contains all true atomic sentences and the negations of those which are false” (p. 10). However, Carnap primarily devised this concept in relation to a semantical system for linguistic analysis. Meanwhile, D knowledge relates to descriptions of a deterministic world. In this regard, these two notions are different. Nevertheless, following Carnap, we will assume that D knowledge is an entirety of atomic sentences that describe a deterministic world.

Regarding Definition (2), the idea of the cognitive agent receiving D knowledge bears a resemblance to the “circular-seeming idea of substituting a string’s own Gödel number into the string itself” (Nagel & Newman, 2001, p. 89). But what is a string? In a formalized system of mathematics, “postulates and theorems” are “‘strings’ (or finitely long sequences) of meaningless marks, constructed according to rules” (p. 26). Further, a Gödel number is a “unique number [assigned] to each elementary sign, each formula (or sequence of signs), [or] each proof (or finite sequence of formulas),” which “serves as a distinctive tag or label” (p. 69). The D knowledge specific to the universe can be likened to the Gödel number assigned to a string (or mathematical theorem). Also, the agent can be compared to a variable in the theorem. Just as the Gödel number for the theorem is substituted into the variable in the theorem, the D knowledge is fed back into the agent’s information processing mechanism. Put simply:

Gödel number (representing a theorem) D knowledge (describing the universe)

Theorem Universe

Variable (included in the theorem) Agent (included in the universe)

Substituting the Gödel number into the variable Providing the D knowledge to the agent

Undoubtedly, the idea of the agent receiving the D knowledge is unconventional and seemingly contradictory. How could someone know about her future if it was predetermined? One way of circumventing this contradiction might be to assume that a particular deterministic world is contained within a larger system and that there exists a mathematical probability that the descriptions in the D knowledge will be at a particular time point provided to the agent from the larger system. Technically speaking, however, that would be an indeterministic world. Accordingly, this paper proposes to examine reception of D knowledge in a metaphysical sense only.[3]

Another unconventional aspect of this paper is the assumption of two apparently identical but different deterministic worlds. For example, Schwartz (2012) defines determinism as the view “that [possible] worlds cannot be the same up to a point and then diverge” (p. 216). However, in our thought experiment, it is possible for two deterministic worlds to be causally the same up to a point and then diverge when D knowledge is provided to them. If one contends that the human mind cannot be fully reduced to an algorithm, it is becomes necessary to assume that such a divergence is possible.

For further discussion, we define the following two metaphysically open deterministic worlds that are established as “ICs.”

(i) The original world like ours that comprises a human agent.

(ii) A simulated world that replicates every aspect of the original world and comprises a machine agent emulating the human agent in a causal manner.[4]

The paper will discuss information processing through computational concepts. According to Beraldo-de-Araújio, the essence of computation is “symbolic manipulation” and concerns “mapping function between two sets of symbols” (Polak & Krzanowski, 2019, p. 6). The human agent’s symbolic manipulation, for instance, may take place through neural activities in the brain. Meanwhile, the machine agent performs symbolic manipulation by processing machine-readable symbols. By slightly changing Beraldo-de-Araújio’s definitions on p.6, this paper defines computation as follows.

(1) A process is a function P: I → O such that its domain I is a set whose elements are called input events and its co-domain O is a set whose elements are called output events, while both I and O are subsets of a physical world. For all xI, y = P(x) (yO) is a corresponding output event.

(2) A computer is a function C: S → T from a set of input symbols S to a set of output symbols T, such that C(x̅) is outputted by computing x̅. (x̅ is a symbolic representation of x.) A process P: I → O is computational if P is generated by a computer C.

In the simulated world, we suppose that the mind is a “classical von Neumann computer” and that “its representation-bearers [are] data structures” (Frankish & Ramsey, 2012, pp. 31-32).[5] This world is intentionally designed to avoid being based on a “connectionist” model.[6] Specifically, it may not be feasible for the connectionist model to accurately emulate the human agent due to its comparatively high stochastic nature. Such a feature might hinder accurate realization of a scripted scenario in which probabilities may be occasionally assigned to counterfactual input events.[7] Although the classical model may be much less sophisticated, it can at least robustly emulate human behaviors in hindsight if all the relevant information is available.

2.1 Type 1

If the D knowledge specific to the simulated world were provided to its agent, the agent would process reception of the D knowledge simply as one of the existing potential input events. This suggests that the agent executes rigid processing, as it cannot process in any other way an input that it was not configured to receive. This world is trivially deterministic in that it is governed by a predefined type of D knowledge (i.e., Type 1) that dictates how things should occur.

Through the IC analogy, the simulated world can be physically characterized by “LH1.” Recall that a right hand cannot enter into LH1. Similarly, D knowledge cannot be provided to the simulated world. Additionally, the simulated world can be metaphysically characterized by “LH2.” If a right hand enters into LH2, it will be perceived no differently than the existing left hand. Likewise, even if the D knowledge were provided to the simulated world, its provision could not be identified by its agent as distinct from all the other existing potential input events.

See the following mappings.  

I = {x1, x2, …, xn}

O = {y1, y2, …, yn}        

Since this is a trivially deterministic world, only one of the input events from x1 to xn is to occur. The pairs other than the actual input-output pair serve to illustrate counterfactual cases. These cases are included in Type-1 D knowledge. Now suppose that reception of D knowledge occurs immediately before a particular event in the input event set does. Then:

xD = xk (xD is reduced to xk.)        1 ≤ k ≤ n

xD = reception of D knowledge

yD = yk

yD = response to reception of D knowledge

However, the above mappings are based on a non-stochastic model, which does not allow for indeterminacy. By supposing for now that the simulated world is indeterministic, we can establish the following mappings.

I = {x1, x2, …, xn}

O = {y1[1], …, y1[s1]}, {y2[1], …, y2[s2]}, …, {yn[1], …, yn[sn]}

xD = xk (xD is reduced to xk.)        1 ≤ k ≤ n

yD = One element from {yk[1], …, yk[sk]} (The probabilities assigned to these stochastic outcomes add up to 1.)

The above stochastic model is meant to show that, even in an indeterministic world, as long as the agent relies on rigid processing, its response to reception of the D knowledge could be nothing other than any one of the predefined output events.

To illustrate the triviality of the simulated world, let us consider a hypothetical scenario involving a clinical psychologist named “Millicent” (or simply “Millie”). She loves coffee but often hesitates whether to drink it. One morning, she decides to have a coffee anyway while watching a seminar video through a tablet device. In this case, suppose that there is a 60% chance that she will stop drinking her coffee if she happens to think that it will do her no good. The following event mappings are established for her in atomic-sentential form:

x1 = The seminar tires me.

x2 = The coffee does not convince me of insomnia.

x3 = The coffee convinces me of insomnia.

y1 = I stop watching.

y2 = I keep drinking.

y31 = I stop drinking.

y32 = I keep drinking.

However, since the world is deterministic, only a particular event such as x1 (which does not allow a stochastic outcome) would have been configured to occur. Meanwhile, in a metaphysical sense, it is possible to assume that specific descriptions in the D knowledge could be provided to her immediately before x1 happens. Suppose that her tablet displays not only the above mappings but also a short history of her activities in the morning and the events to unfold throughout the day. How would she respond?

From a humanistic perspective, there must be a distinct mental representation corresponding to the event of “I see the descriptions.” However, Millie’s rigid processing mechanism would only be able to interpret the sight of the display as one of x̅1 to x̅3. Recall that Millie’s mind follows the classical computer model whose representation-bearers are data structures. Since she only executes rigid processing, a bit structure corresponding to her symbolic representation of the event would most probably be translated to a particular bit structure corresponding to one of x̅1 to x̅3. Suppose that it is interpreted as x̅3. Then, her processing mechanism would output either one of y̅31 and y̅32. Given the 60% chance, it would probably output y̅31, which should be accompanied by y31. In other words, she would probably stop drinking her coffee in response to receiving the D knowledge.

2.2 Type 2

If the D knowledge specific to the original world were provided to its agent, the agent would process reception of the D knowledge as a different input event than all the other previous potential input events. This means that the agent’s processing mechanism exhibits emergent processing, as it can distinctly identify a particular input event that was not supposed to happen. This world is non-trivially deterministic. Using the IC analogy, it can be physically characterized by “RH1” and metaphysically by “RH2.” Further, it is possible (rather than necessary) that the D knowledge only reflects every physical event across time. Unlike Type 1, this type of D knowledge (namely, Type 2) does NOT include counterfactual cases. Also, this knowledge is compatible with the block universe theory.

In the block universe model, “[w]hether past, present or future, all events ‘lie frozen’ in the four-dimensional block, much like the scenes from a movie are fixed on the film roll” (Thyssen, 2020, p. 6). If one were to see the events of the universe like fixed scenes on a film roll from an omniscient viewpoint across time, she might be able to extrapolate to a certain extent counterfactual cases in relation to those events. However, the scenes themselves do not include such information. In that sense, Type-2 D knowledge only mirrors the physical events.

Meanwhile, we assume that emergence of a new output in response to D knowledge reception is necessary, considering that the agent’s processing mechanism is assumed to be governed by causality. However, the content of the new output may be deterministic or non-deterministic. This is highlighted by the question mark in the input-output mappings below. The pairs other than the actual input-output pair are provided as dummies whose contents are unknown (i.e., the counterfactual cases are unknown). “xn+1” (i.e., reception of D knowledge) is enclosed in parentheses to indicate that it is only a latent event in a metaphysical sense.

I = {x1, x2, …, xn,(xn+1)}

O = {y1, y2, …, yn, (?)}  

xD = xn+1                          yD = ?   

If the Millie scenario happened in the original world, she might have been struck to the core and asked, “Am I living in a Matrix?” by emergently interpreting D knowledge reception.

2.3 Type 3

Despite its assertion that the past, present, and future all coexist, the block universe theory does not demand absolute causality. Polkinghorne (2007) notes that “[b]elievers in the block universe are not forced to commit themselves to a deterministic account of its causal structure” (p. 977). However, assume that the original world is thoroughly deterministic in a causal sense. Then, one can entertain the idea that its agent’s decision-making processes are strictly deterministic in a metaphysical as well as physical sense. Specifically, the agent should produce a new output (whose content is deterministic) in response to receiving D knowledge of Type 2. This hypothetical situation would generate a derivative version of D knowledge (namely, D’). Then, the agent should produce another output in response to receiving D’, thereby generating another derivative version of D knowledge (namely, D’’). To aid in understanding this somewhat complex scenario, let us go back to the Millie story. With regard to the Millie of the original world, D’ knowledge might state as follows:

“Millie responds to D knowledge. She speaks, “Am I living in a Matrix?”

D’’ knowledge might state:

“Millie responds to D’ knowledge. She speaks, ‘I might need to take some medication to calm my caffeine-induced paranoia. Or maybe this world that I’m living in was monstrously rigged, and I must somehow survive by figuring out how I first reacted to… I don’t know, but it seems like this situation that I’m in happened already once before, and I must figure out whatever this evil gadget had said in the first place. Let me think… Whatever action I take right now, was that also predetermined?’”

See the following formal mappings:

I = {x1, x2, …, xn, (xn+1), (xn+2), … }

O = {y1, y2, …, yn, (yn+1), (yn+2), …}

xD = xn+1                          yD = yn+1                         

xD’ = xn+2                             yD’ = yn+2

…                                    …        

The above mappings may develop indefinitely.[8] All these potentially infinite counterfactual cases are included in Type 3.[9] Further, it can be said that this type of knowledge is generated by an inherent configuration of the world.[10] For instance, Tegmark (2008) argues that it is “plausible that our universe could be simulated by quite a short computer program” (p. 18). Based on the idea that “our universe is mathematics” (p. 1), he maintains that its realization only requires storage of “all the 4-dimensional data” (i.e., all the “[encoded] properties of the mathematical structure that is our universe”) (p. 18). He states that a “complete description” of a mathematical structure is “a specification of the relations between the elements” of the mathematical structure (p. 18). As such, the 4-dimensional data primarily relate to the abstract realm of mathematics. If his argument is true, we would not need any type of D knowledge (consisting of verbal descriptions in atomic-sentential form) in order to simulate a universe. Rather, D knowledge would be a byproduct of the mathematical structure and its specification.

 

3. The Vantage Point Problem

This section explores how the “vantage point problem” stated in this paper’s introduction can be addressed by relying on the concept of D knowledge. Let us first look into two philosophical cases where this problem has not been properly addressed.

(1) Tegmark[11] (2008) asserts that “[t]here exists an external physical reality completely independent of us humans” and that “[o]ur external physical reality is a mathematical structure (p. 1). However, despite his convincing arguments, he still fails to address the vantage point problem. In footnote 3 on p. 5, he notices the problem of how a mathematician should derive, through (i) a mathematical structure alone, (ii) an empirical domain and (iii) “a set of correspondence rules which link parts of the mathematical structure with parts of the empirical domain.” He hints at a possibility of achieving this by introducing a “car” analogy. Specifically, “given an abstract but complete description of a car (essentially the locations of its atoms),” “someone” that wants “practical use of this car” might “be able to figure out how the car works and write her own manual” by “carefully examining the original description.” Put simply:

“Someone” Mathematician

Description of the car Mathematical structure of the universe

Practical use of the car Empirical domain of the universe

Knowledge of how the car works Correspondence rules linking the mathematical structure with the empirical domain

While the mathematician is part of the universe, that “someone” is not part of the car. Therefore, the car analogy fails. In fact, the above analogy well illustrates a common mistake made by scientists as well as philosophers – namely, the confusion that arises from the vantage point problem.

(2) Dennett (2003) notes that "confusion [over determinism] arises when one tries to maintain two perspectives on the universe at once" (p. 93). One perspective is the "God's eye" perspective, and the other is the "engaged perspective of an agent within the universe" (p. 93). His description of the former perspective coincides with the Parmenidean view of the universe. Specifically, he states that "[f]rom the timeless God's-eye perspective nothing ever changes" as "the whole history of the universe is laid out 'at once'" (p. 93). Dennett appears to give equal weights to both perspectives but cautions against assuming them at the same time. He does not provide a philosophical scheme where both perspectives can coexist.

The two cases illustrate the ongoing struggle of scientists and philosophers to reconcile the discrepancy between a human agent making a declarative statement (i.e., a deterministic worldview) about the universe at large and the universe where the agent belongs. It is believed that this paper has resolved this issue to a certain extent. Unlike machines, human intelligence is capable of emergently processing -- to use a bit of an oxymoron -- even “otherworldly but comprehensible” knowledge (i.e., D knowledge). By definition, D knowledge is an entirety of verbal descriptions encompassing the whole universe. This type of knowledge is inaccessible in principle; therefore, it can be considered to exist in an “otherworldly” realm. Nevertheless, it is deemed “comprehensible” from the human agent’s perspective, as evidenced by its capacity to provide a non-trivial response to D knowledge. This has a metaphysical implication that the human agent could potentially view the universe from a vantage point situated in a realm beyond the universe despite actually being part of the universe. However, for machine intelligence, D knowledge is neither “otherworldly” nor “comprehensible.” In fact, there is no type of information at all that can be genuinely comprehended by machine intelligence. This is demonstrated through the triviality of responses it might generate with regard to D knowledge in Section 2.1.

Further, the same level of triviality could be said to be exhibited by a hypothetical agent whose declaration of determinism should be assumed to be qualitatively inseparable -- in a pancomputational[12] sense, for instance -- from all the other events of the universe. If no distinction is made between such an act of declaration and the events of the universe that are yet to include the act of declaration, no scholarly discussion on determinism would have any meaning. Therefore, the declaration of determinism should by necessity stand out by acquiring a particular metaphysical meaning in the midst of all the events of the universe. This is achieved by granting a privileged status to a determinist regardless of the truthfulness of her argument. The grant of such a status can be justified by her inherent capacity to comprehend D knowledge. Finally, note that this peculiar dynamics between the determinist and the universe can be best described through a dialectic circle in Maybee (2020, Section 1). This circle grows as the determinist and the objects/events of the universe continue to encircle each other in an alternating manner. It is this dialectic circle that provides Wittgenstein’s (1922) “metaphysical subject” (p. 75) with a holistic scheme for investigation of the universe.

 

4. Summary

The major ideas of this paper can be outlined as follows.

(1) Deterministic knowledge

l  Type 1

n  Dictates the world.

n  Includes finite counterfactual cases.

l  Type 2

n  Reflects the world.

n  Includes no counterfactual cases.

l  Type 3

n  Is generated by the world.

n  Includes infinite counterfactual cases.

(2) Metaphysically open deterministic worlds

l  Trivially deterministic world

n  Its agent executes rigid processing.

l  Non-trivially deterministic world

n  Its agent executes emergent processing.

Based on the above conceptual scheme, this paper has sought to distinguish human from machine intelligence by allowing for hard determinism. In accordance with this scheme, it attempted to answer the question of how to establish a qualitative distinction between a human agent as an investigator of the universe and the universe that the agent belongs to.

[1] Wittgenstein (1922) notes that “the philosophical I” is a “metaphysical subject” that is “not a part of the world” (p. 75). Determinism is a philosophical judgment imposed upon the world by the determinists. Thus, the determinists’ reasoning mind should not belong in the world.

[2] Vihvelin (2023) proposes “[leaving] open the metaphysical possibility of time travel to the past and backwards causation” (Abstract). These concepts are philosophically worth considering even though they unlikely to materialize in reality. Similarly, although an agent can never know the future with certainty, we can at least consider the possibility.

[3] We assume that the cognitive agent receives only a “small breadth” of D knowledge that is associated with the agent. The entirety of D knowledge would be too immense to be processed by any agent.

[4] Müller (2014) validly distinguishes between two different physical processes P1 and P2, which perform the same computation C (p. 9). Similarly, the original and simulated worlds are computationally the same but ultimately different.

[5] A representation-bearer is a means through which an object being represented is thought/perceived by an agent. See Frankish & Ramsey (2012, p. 9).

[6] Connectionism suggests that “individual neurons do not transmit large amounts of symbolic information” and that “they compute by being appropriately connected to large numbers of similar units” (Feldman & Ballard, 1982, p. 208). Testing whether a connectionist-based AI could think like humans may require a different approach (e.g., Schneider’s (2019) ACT test (p. 54)).

[7] The Millie scenario to be discussed in Section 2.1 includes stochastic outcomes in response to a counterfactual input event.

[8] Similarly, Sterelny (1990) notes that the “ability to think about the world as it is and as it might be, to think indefinitely many and indefinitely complex thoughts” may be a “necessary condition on having intentional states” (p. 29).

[9] When considering the infinite counterfactual cases, we see that there can be no predefined type of D knowledge (i.e., Type 1) that dictates a non-trivial world.

[10] This configuration may be unidentifiable as demonstrated in the Kantian antinomies (Kant, 1998, pp. 470-495).

[11] Tegmark is a determinist. He supports Einstein’s dictum that “God does not play dice” (p. 10).

[12] According to pancomputationalism, “everything is a computing system” and “minds are computing systems too” (Piccinini, 2007, p. 95).
