NOTE: If we wish to reach the real origin of this hypothesis of Practical Reason, we must trace its descent a little further back. We shall find that it is derived from a doctrine, which Kant totally confuted, but which nevertheless, in this connection, lies secretly (indeed he himself is not aware of it) at the root of his assumption of a Practical Reason with its Imperatives and its Autonomy — a reminiscence of a former mode of thought. I mean the so-called Rational Psychology, according to which man is composed of two entirely heterogeneous substances — the material body, and the immaterial soul. Plato was the first to formulate this dogma, and he endeavoured to prove it as an objective truth.
