Against free energy, for direct perception.

Area of Science:

• Cognitive Science
• Theoretical Physics
• Philosophy of Mind

Background:

• The Free Energy Principle (FEP) is a proposed unifying theory in neuroscience and physics.
• The FEP suggests that perception inherently involves inferential processes to minimize prediction error.
• Current applications of FEP in physics are being critically examined.

Purpose of the Study:

• To critically evaluate the validity and applicability of the Free Energy Principle within contemporary physics.
• To challenge the assumption that perception, particularly of social affordances, necessitates inferential reasoning.
• To propose that direct perception is a viable alternative to inference-based models.

Main Methods:

• Philosophical analysis of the Free Energy Principle's foundational assumptions.
• Conceptual critique of the link between perception and inference.
• Exploration of alternative theories of direct perception.

Main Results:

• The Free Energy Principle's grounding in physics is questioned, potentially undermining its broader theoretical claims.
• The necessity of inference for all forms of perception is challenged.
• Evidence suggests that direct perception, without inference, is possible for various perceptual modalities, including social affordances.

Conclusions:

• The Free Energy Principle may not be a universally applicable or correct framework in physics.
• Perception does not exclusively rely on inference; direct perception is a plausible mechanism.
• Rethinking the role of inference in perception opens new avenues for understanding cognitive processes and social interactions.
