This paper has three main aims. First, I criticize intellectualism in the philosophy of mind and I outline an alternative to intellectualism that I call Concept Pluralism. Second, I seek to unify the sensorimotor or enactive approach to perception and perceptual consciousness developed in  O’Regan  &  Noë  ( 2001 ) and  Noë  ( 2004 ,  2012 ), with an account of understanding concepts. The proposal here —that concepts and sensorimotor skills are species of a common genus, that they are kinds of skills of access —is meant to offer an extension of the earlier account of perception. Finally, I describe a phenomenon —fragility —that has been poorly understood, but whose correct analysis is critical for progress in the theory of mind (both perception and cognition).
