Kant soul

kant defines the soul as the thinking self. he says it can be called a substance, as the ultimate subject of thinking which cannot itself be further represented as predicate of another thing, so it must have permanence. Permanence can only be proved for the purposes of experience, never out of the concept of a substance as a thing in itself. If therefore, we want to infer permanence of the soul from the concept of the soul from the concept of the soul as substance, this can only be valid of the soul for the purposes of possible experience, and not valid of it as a thing in itself and beyond all possible experience. The subjective condition of all possible experience is life, therefore only the permanence of the soul in life can be inferred, for the death of a human is the end of all experience. thus the permanence of the soul can only be shown in the life of a human, but not after death. And this on the concept of substance, insofar as it is to be regarded as necessarliy joined with the concept of permanence, can only be so joined according to a principle of possible experience and therefore only for the purposes of experience. The connection of the appearances of the objects outside a person according to laws of experience, proves the objective truth equally as the connection of the appearance of the inner sense proves the actuality of a person's soul. Kants says he knows his soul only as an object of inner sense, through appearances which constitute an inner state, and the essence of it in itself, which lies at the ground of these appearances, is unknown.
