 Kant thus distinguishes between rationally-oriented (ontotheological) and empirically-oriented (cosmotheological) discussion.Consistently with Kant's definition, philosophical and theological writers sometimes use the words "ontotheology" or "ontotheological" to refer to the metaphysical or theological views characteristic of many rationalist philosophers.Heidegger, discussed below, later argued for a broader definition of the word ontotheology.
