Ryle criticizes the theory that the mind is a place where mental images are apprehended, perceived, or remembered. Sensations, thoughts, and feelings do not belong to a mental world which is distinct from the physical world. Knowledge, memory, imagination, and other abilities or dispositions do not reside "within" the mind as if the mind were a space in which these dispositions could be placed or located. Furthermore, dispositions are not the same as behavioral actions, but actions may be explained by dispositions.
