Philosophy belonging to the age of self-critical reason

 Philosophy as first blush should be anti-teleological

 disdain illegitimate valorizing and not lay claims to

proto-existentialist experience of the finality of human life.

For philosophy is seen as fundamentally self-reflexive in nature, as belonging to the age of self-critical reason; that is, it is linked up with the quest not only for first-order knowledge of nature and human being, but also for second-order knowledge of what human knowledge involves in the first place.
