b. 1950
Christopher Peacocke is a British philosopher known for his influential work on the theory of concepts, philosophy of mind, and epistemology. His account of concept possession in terms of determination theories and possession conditions has been central to debates in analytic philosophy of mind and cognitive science.
Developed a systematic theory of concept possession based on possession conditions and determination theories
Authored 'A Study of Concepts' (1992), a foundational work in the philosophy of concepts
Advanced the notion of nonconceptual content in perception
Contributed to debates on self-knowledge, rationalism, and a priori justification
Held chairs at Oxford, NYU, and Columbia, shaping contemporary philosophy of mind
Because the agent's aversive mood is fragile, the possibility of her trying to eat a red candy is a close one, so she also satisfies condition (ii).
premiseDespite satisfying both (i) and (ii), this agent lacks the ability to eat a red candy in precisely the same way as Lehrer's original agent.
premisePeacocke's proposal requires that an agent satisfy both condition (i) and condition (ii) to possess an ability.
premiseAn agent whose aversion to red candies is an unpredictable and temporary mood satisfies condition (i) for the same reason as Lehrer's original agent.
Because the agent's aversive mood is fragile, the possibility of her trying to eat a red candy is a close one, so she also satisfies condition (ii).
premiseDespite satisfying both (i) and (ii), this agent lacks the ability to eat a red candy in precisely the same way as Lehrer's original agent.
claimPeacocke's proposal is subject to modified versions of Lehrer's counterexample and therefore fails to overcome the sufficiency objection.
premiseAn agent whose aversion to red candies is an unpredictable and temporary mood satisfies condition (i) for the same reason as Lehrer's original agent.
