Transcendental history denotes a possible philosophical discipline on a par with transcendental logic. Through two mutually complementary endeavours, namely the working out of a notion and the defending of a thesis, Gosvig Olesen examines the history of philosophy in areas where the possibility of the transcendental history will emerge. The notion that is worked out is the notion of historical time. The thesis that is being defended is that the human cognition's transcendental condition is history. Notion as well as thesis place the dissertation in the philosophical genre traditionally known as transcendental philosophy.
