IV. The Starting Point of Epistemology

We must be completely clear that what is brought forth in the act of knowing must have been given fresh and unmodified. Conclusive inferences are not necessary to recognize this. This already shows that the sensory qualities do not satisfy our requirements, because we do not know directly that these do not arise without our activity, but only through physical and physiological considerations. But we do know directly that concepts and ideas always first enter the sphere of unmodified-given in and by the act of knowing. Therefore no one is mistaken about this characterization of concepts and ideas. One can certainly consider hallucinations to be something given from outside, but one will never believe that its concepts are given to us without our own work of thinking. A madman considers certain things and conditions to be real, and endows them with the label “reality”, even though there are no facts to back that up. A madman will never say, however, of his concepts and ideas, that they enter the world of the “given” without his own activity. Everything else in our worldview has such a character that it must be ‘given’ if we want to experience it, and only with concepts and ideas does the reverse hold true. We must produce Ideas and concepts if we want to experience them.
