Final answer:
The issue with eliminative materialism is the lack of empirical support for its claim that only material substance exists and the mind does not have an independent existence. This stance conflicts with the intuitive certainty many have about their own mental experiences, contributing to a philosophical paradox regarding subjective consciousness.
Step-by-step explanation:
The issue with eliminative materialism, which posits that only material substance exists and dismisses the existence of the mind as an independent entity, is the lack of empirical support. This stance is challenged by the intuitive certainty many people have of the existence of their own minds, which often takes priority over materialist explanations. This certainty of personal mental experience presents a significant challenge to the materialist view, as it seems to directly contradict the eliminative materialist's assertion that mental states do not exist independently of the physical brain.
Eliminative materialism is contrasted with dualism, which maintains that mind and body both exist, and idealism, which holds that only spiritual substance exists. Critics of eliminative materialism argue that it fails to adequately account for subjective experiences and the phenomena associated with consciousness. Furthermore, philosophical paradoxes arise when considering how the material brain produces the subjective quality of experience known as the 'hard problem of consciousness'. An approach that honors both empirical evidence and subjective experience may be required to navigate these issues.
As such, the correct answer to the given question regarding the issue with eliminative materialism is A) Lack of empirical support.
