I. The Human Soul's Activities in the Course of Time

One could accept that these supersensible elements can be denied; but there is one thing that a person cannot deny, namely, that he perceives three kinds of inner experiences within himself. One is that he experiences representations in his soul. For everyone knows that when he looks at an object and then turns around and still has the impression of it, he has experienced a representation. The second thing that a person experiences, and which he must distinguish from his perceptions, are the emotions: pleasure and pain, joy and sorrow, sympathy and antipathy. And there is a third thing that a person cannot deny: that he has impulses of will.
