I will argue from various examples that the inaccessibility of As in terms of Bs need not imply that As do not exist, pointing to such conceptual fault-lines involving legal concepts, aesthetic concepts, and meanings of language.   We make  conceptual jumps when we learn to apply a new vocabulary that cannot be defined in terms we already understand.    I hope to throw light on the differences between intentional action and bodily processes and movements.
