Freiheit zur Wahrheit
How do our perceptions come about? If our ways of forming them is deterministically given, skeptical objections can no longer be warded off. We might as well be calibrated for errors. If, instead, our cognition works unbounded and free, there is no compulsion to fall prey to error. It is therefore advisable to understand cognitive formation as a plurimodal interaction of activities of perception, imagination and verbalization, the course of which is never determined by the conditions under which it currently stands. Further, we should not describe ourselves as mere "res cogitans," no matter what the philosophical intentions: there is no sense in assuming that we are determined to perform activities of cognition only. In dealing with two major historical examples, these assumptions are developed and tested. It is shown why René Descartes unexpectedly champions them, and which consequences ensue from John Locke´s disregarding them.
