In this phenomenology, where, at first glance, and if one takes inspiration from traditional schemas, motifs of conflict or of tension appear numerous (it is a philosophy of essences always considered in their objectivity, their intangibility, their apriority; but, by the same token, it is a philosophy of experience, of becoming, of the temporal flux of what is lived, which is the ultimate reference; it is also a philosophy in which the notion of transcendental experience designates the very field of reflection, in a project which, in Kant's eyes for example, would have derived from teratology), one finds no clashes; and the mastery of the phenomenologist at work would have assured Husserl of a perfect serenity in the usage of these two always complementary operative concepts.
