Introduction
The debate surrounding free will has captivated philosophical discourse for centuries, especially when scrutinizing the compatibility of free agency with determinism. In contemporary philosophy, the concepts of free will are often delineated into distinct senses, notably the compatibilist ([FC]) and libertarian ([KL]) perspectives. To engage with these notions critically, it is essential to reconstruct the philosophical arguments presented in Acts 2 and 3 of Lemos, which embody these senses of freedom. This paper systematically reconstructs these arguments using formal logic techniques—modus ponens and modus tollens—then critically examines their premises' plausibility, ultimately evaluating which argument holds greater logical and philosophical weight.
Reconstruction of Acts 2 Argument Supporting the [FC] Sense of Freedom
The main argument from Act 2 advocating the [FC] or compatibilist notion of freedom can be formulated as follows:
If an agent acts voluntarily and without external coercion, then the agent is free in the compatibilist sense. (Premise)
The agent in Act 2 acts voluntarily and without external coercion. (Premise)
Therefore, the agent in Act 2 is free in the compatibilist sense. (Conclusion)
Expressed in modus ponens form:
Premise 1:
If A, then B.
Premise 2: A.
Conclusion:
B.
Here, A corresponds to the agent acting voluntarily without coercion, and B corresponds to the agent being free in the compatibilist sense. The second premise is justified because Act 2 depicts the agent making choices consistent with their desires, unimpeded by external forces, aligning with the compatibilist understanding of free agency grounded in psychological autonomy.
Justification of the Second Premise of the MP Argument
The justification relies on textual evidence where Act 2 describes the agent’s decisions as rooted in their rational desires and intentions, free from coercion. The premises assume that voluntary action and absence of external constraints suffice for freedom in the compatibilist framework, which is widely supported in philosophical literature (Frankfurt, 1969; compatibilist theories, Dennett, 1984). This premise supports the view that acting according to one’s internal motivations without external interference aligns sufficiently with our intuitive concept of freedom, making the second premise plausible within this context.
Reconstruction of Acts 2 Argument Using Modus Tollens
The same hypothetical premise as above is used:
If an agent acts voluntarily and without external coercion, then the agent is free in the compatibilist sense. (Premise)
The agent in Act 2 is not free in the compatibilist sense. (Premise)
Therefore, the agent in Act 2 did not act voluntarily and without external coercion. (Conclusion)
This formulation directly challenges the idea that acting voluntarily and uncoerced necessarily results in compatibilist freedom. The second premise is supported if textual analysis reveals instances where the agent's decision processes are influenced by subconscious biases or internal conflicts, which could
undermine their free agency according to certain compatibilist or libertarian critiques (Kane, 1996).
Justification for the Second Premise of the MT Argument
The justification hinges on textual instances indicating internal psychological struggles or subconscious influences, as discussed in Act 2. Such complexities could mean the agent’s actions, despite appearing voluntary, are not fully free under the compatibilist criteria. This aligns with philosophical critiques emphasizing that internal determinism or psychological influences can compromise genuine freedom (Kane, 1996; Mele, 1995).
Evaluation of Soundness for the Acts 2 Arguments
Assuming that the first argument (modus ponens) is valid and its premises are true, it appears to be sound within the context of Acts 2, where actions seem to stem from internal desires aligned with rationality and free choice. Their justification appears compelling, provided we accept the compatibilist account of free agency.
Conversely, the modus tollens argument depends heavily on the truth of the second premise—that the agent was not free—based on internal psychological influences. Since textual evidence may be ambiguous, this premise's truth value is less certain, making this argument less reliably sound unless such influences are convincingly demonstrated.
Therefore, the argument supporting the [FC] sense in Act 2, reconstructed via modus ponens, appears more plausible and likely to be sound, given the textual support for voluntary, rational decision-making without external coercion.
Reconstruction of Acts 3 Argument Supporting the [KL] Sense of Freedom
The philosophical position from Act 3 emphasizing the [KL] or libertarian sense of freedom can be represented as:
If a free agent's choices involve undetermined quantum events at the brain level, then the agent is free in the [KL] sense. (Premise)
Quantum indeterminacy occurs at some stage during the decision-making process in Act 3. (Premise)
Therefore, the agent in Act 3 is free in the [KL] sense. (Conclusion)
Expressed in modus ponens:
Premise 1:
If quantum indeterminacy influences decision, then the agent is free in the [KL] sense.
Premise 2:
Quantum indeterminacy occurs in the agent’s decision process.
Conclusion:
The agent in Act 3 is free in the [KL] sense.
The second premise relies on the premise that quantum events comprise the fundamental indeterminacies at the neurophysiological level affecting choices, a hypothesis supported by interpretations of quantum mechanics intersecting with neurophilosophy (Hossenfelder, 2019; Pearle, 2019). This aligns with libertarian notions that real freedom involves genuine indeterminacy, unlike deterministic or compatibilist accounts.
Justification of the Second Premise of the KL Argument
Textual analysis in Act 3 suggests that the agent’s choices involve unpredictable quantum influences, possibly emerging from probabilistic neurobiological processes. This provides a basis for the idea that such indeterminacy allows for metaphysical free will (Libet, 1985; Mitcheson & Fried, 2014). The assumption is that quantum uncertainty at the neuronal level could be the source of undetermined decisions, consistent with libertarian free will. These interpretations find some support in contemporary neurophilosophy, though the empirical evidence remains debated (Hossenfelder, 2019).
Reconstruction of the
Negation
(Modus Tollens) for Acts 3
The same hypothetical premise as above is used:
If quantum indeterminacy influences decision, then the agent is free in the [KL] sense. (Premise)
The agent in Act 3 is not free in the [KL] sense. (Premise)
Therefore, quantum indeterminacy does not influence the decision process in Act 3. (Conclusion)
This formulation challenges the claim that quantum indeterminacy necessarily results in libertarian free will. The second premise would be justified if, despite the potential quantum influences, the text indicates that the agent's choices are still influenced by hidden deterministic factors or neurobiological constraints
that invalidate genuine indeterminacy for free will (Mele, 2009).
Justification for the Second Premise of the KL MT Argument
If textual evidence suggests the agent’s decisions are ultimately determined by subconscious neurobiological constraints or probabilistic influences that fail to produce genuine freedom, then the second premise holds. This position aligns with critiques emphasizing that quantum indeterminism alone may not suffice for metaphysical free will, especially if neurobiological mechanisms remain deterministic or probabilistically constrained (Hughston & Mielke, 1987; Busemeyer et al., 2012).
Evaluation of the Soundness of the Acts 3 Arguments
Assuming both arguments are valid, the soundness depends on the empirical and philosophical plausibility of their premises. The modus ponens version from Act 3 relies on the occurrence of quantum indeterminacy affecting decisions, a contentious yet increasingly explored hypothesis. The second premise’s truth is debated but supported by some interpretations of quantum neuroscience, making the argument somewhat plausible.
In contrast, the modus tollens version’s second premise rests on textual evidence suggesting deterministic neurobiological influences override quantum indeterminacy, which some philosophers and neuroscientists argue is more consistent with the available evidence. Therefore, the argument negating quantum influence (second premise) might be more empirically and philosophically plausible.
Consequently, the argument supporting the [KL] sense of free will appears less certain to be sound, given the current state of neurophilosophical evidence. However, due to the idealized nature of the philosophical reconstruction, both arguments serve primarily as logical tools rather than definitive proofs.
Conclusion
In conclusion, the logical reconstruction affirms that the argument supporting the [FC] or compatibilist notion of freedom from Act 2 is more convincingly sound based on the textual evidence emphasizing voluntary and rational agency uncontaminated by external coercion. The libertarian [KL] account from Act 3, while grounded in compelling scientific hypotheses about quantum effects, faces more significant empirical and philosophical challenges for its premises' certainty. Therefore, the compatibilist view of free will, as articulated in the Act 2 argument, presently holds a more robust logical and philosophical standing.
