Man is always something more than what he knows of himself. He is not what he is simply once and for all, but is a process... - Karl Jaspers

A critical approach to science calls for the abandonment of world systems, which is also a prerequisite to any philosophical apperception of being. True, the philosophical quest of being demands a familiarity with every branch of scientific inquiry. But it seems to be the hidden aim of science to attain through inquiry to a limit at which the area of nonknowledge is opened to the most lucid knowledge. For only fulfilled knowledge can lead to authentic nonknowledge. Then authentic being is revealed not in any world system built on knowledge but in fulfilled nonknowledge, which can be achieved only through scientific cognition, not without it and not before it. It is the supreme striving of knowledge to reach the point where cognition fails.

We must all continuously recapture ourselves from indecision.

In time, this consciousness of risk remains the condition for increasing freedom. It excludes complete reliance on subjective certainty, forbids the generalization of the subjective commandment into a universal law, and bars fanaticism. Even in the certainty of the resolve, there must, in so far as it is translated into practical action, remain a certain margin of indetermination. There can be no subjective security. The pride of the absolute truth destroys in truththe world.
