Metaphysics of concepts: In defense of the abilitist approach

Abilitism is an approach to the metaphysics of concepts according to which each concept consists of a managing cognitive ability coordinating other abilities (cognitive and non-cognitive) and a set of subordinate abilities associated with this managing ability. As I argue here, if we accept the abilitist approach, we can efficiently solve such puzzles in the metaphysics of concepts as the partial possession problem, the concept pluralism problem, etc. However, there are some possible objections to abilitism, concerning the abilitist explanation of compositional properties of concepts, knowledge-that, an extension/intension of concepts, and the idea that concepts are constituents of thought. However, as I demonstrate here, these objections can be answered.
