Final answer:
Pat Churchland argues for Eliminative Materialism, which is a stance that denies the existence of a separate mental substance and instead explains mental processes in terms of physical brain activities.
Step-by-step explanation:
The question revolves around the philosophical stance that Pat Churchland takes regarding the mind-body problem, specifically whether she supports Substance Dualism, Eliminative Materialism, or neither of these positions. Substance Dualism posits that there are two fundamental types of substance, the mind and the body, which interact with each other. In contrast, Eliminative Materialism is a form of monism that argues against the existence of the mind as a separate entity from the brain, proposing that what we traditionally think of as 'mental states' are better explained by understanding the physical processes of the brain.
Based on the provided reference to Pat Churchland's interview on Philosophy Bites, we can deduce that Churchland argues for Option 2: Eliminative Materialism. She is known for being a proponent of this perspective, which contends that common-sense concepts like beliefs and desires will eventually be eliminated as science progresses and provides a more accurate understanding of brain functions.
