 This same kind of complaint is lodged against each of the paralogistic syllogisms that characterize Rational Psychology. Thus, Kant argues against the inference to the simplicity of the soul, by remarking that the psychologist surreptitiously deduces the actual simplicity of a metaphysical object simply from the formal features of subjectivity (the fact that the “I” is unitary in our representational economy). The personal identity of the soul is attacked on similar grounds. In each case the metaphysical conclusion is said to be drawn only by an equivocation in the use or meaning of a concept of the understanding.
