Reflection upon and repositioning of philosophical studies are their own justification in any civilized era. As Karl Jaspers said, liberty is man's path in time.2 Along the same lines, it may be said that, in a sense, philosophy is liberty's path in thought. Compared with other more concrete branches of science, the subject fields and positioning of philosophy always seem to be an open question. Real philosophy is the self-testimony and presentation of man's existential meaning in each and every period. Rather than staying in fixed subject fields and positions, philosophy is always on the move along a never-ending path of existence. Rather than being a given, static, abstract and closed theoretical system, or formulae and principles that may be discovered and applied once and for all, philosophy is a kind of unceasing rational reflection and cultural critique inherent in human history and human existence.
