Abstract
What seems to bring the systematic and historical approaches into harmony is “philosophical conscience.” By this is meant “evaluating consciousness” that is “self-distancing” and prompts further searching and more careful expression of ideas. “The experience of thinking referred to here—the tension between the practice of verbal experiments and the nonverbal ‘conscience’ with which this practice tries to coincide—corresponds to the way in which we experience moral, aesthetic, and religious realities”. In brief, “a philosopher who tries to think radically … takes the great chance of undermining his own thought”. “History” is generated by the discontinuity resulting from this process of radical philosophizing especially about the basic foundations.
