Difficulty: Very hardComparative Reading: Main Point and Contention

Passage A
The persistence of the mind-body problem stems from the fundamental asymmetry between objective physical properties and subjective conscious experience. Reductive physicalism attempts to explain consciousness entirely in terms of neural mechanisms and functional states. However, this approach inevitably leaves out the qualitative character of experience—what it is like to perceive the redness of an apple or the sharpness of a pain. Even if we possessed a complete neurobiological account of the brain’s processes, this objective description would not logically entail the subjective feeling itself. This "explanatory gap" is not merely an artifact of our current scientific ignorance, but a principled limitation of the physical sciences. Physical properties are essentially structural and relational, whereas conscious experiences possess an intrinsic, qualitative nature. Therefore, any exhaustive physical description of the universe will be inherently incomplete, requiring us to acknowledge an irreducible, non-physical aspect of reality.

Passage B
Proponents of property dualism often cite the "explanatory gap" as evidence that conscious experience cannot be reduced to physical brain states. They correctly observe that the subjective quality of experience defies logical deduction from physical principles, but they draw a flawed ontological conclusion. This intuition, while rhetorically powerful, rests on a misunderstanding of how our cognitive architecture represents information. The gap is not an ontological divide in reality, but an epistemological illusion generated by our brain's disparate representational systems. When we introspect on a conscious state, we employ phenomenal concepts that are immediate and lack internal structural articulation; when we engage in scientific inquiry, we use physical concepts that are purely relational. The fact that we cannot logically deduce a phenomenal concept from a physical one merely reflects this dual architecture, not a divided universe. As theoretical neuroscience progresses, it will explain precisely why specific neural architectures generate these parallel introspective formats, thereby dissolving the illusion of the gap rather than bridging it.

Statement
The authors of Passage A and Passage B would both agree that the concepts scientists use to describe physical mechanisms cannot be used to logically deduce the qualitative concepts we use to describe our conscious experiences.

Based on the passages provided, is the statement above true or false?

Answer: Answer

Answer

True
The statement accurately captures a shared premise. Passage A uses the inability to logically deduce subjective feelings from physical descriptions as proof of an 'irreducible, non-physical aspect of reality.' Passage B, while rejecting the dualist conclusion, explicitly concedes the epistemological premise, stating that we 'cannot logically deduce a phenomenal concept from a physical one' due to our brain's disparate representational systems.

Step-by-Step Solution

1
Analyze Passage A's position on the deducibility of conscious experience.
Passage A asserts that a complete neurobiological description 'would not logically entail the subjective feeling itself,' establishing that physical concepts cannot deduce qualitative experience.
To identify the first author's stance on the core premise of the statement.
2
Analyze Passage B's position on the same deducibility issue.
Passage B states that dualists 'correctly observe that the subjective quality of experience defies logical deduction' and acknowledges 'the fact that we cannot logically deduce a phenomenal concept from a physical one.'
To identify the second author's stance and determine if it aligns with the first author.
3
Synthesize the findings to evaluate the statement.
Both authors explicitly agree that logical deduction from physical concepts to qualitative/phenomenal concepts is impossible. They only disagree on what this impossibility proves about the nature of reality.
To determine the final truth value of the statement.
