ABSTRACT
This chapter presents the concepts of essences, as the object-determining universal that is posited in each particular state of affairs meant in intentio recta. In view of the change from the non-propositional to the propositional attitude, the peculiar correlation between essence and concept can be determined. Husserl contributed to the fact that this rational moment of his phenomenology smelled of irrationalism and esotericism. Such that the two components of Husserlian phenomenology: the eidetic and the transcendental have been discussed. In the first part of this chapter, Husserl's provides a detailed explication of the notion of pure descriptive essence, which is crucial for Husserl's descriptive eidetics, by departing from a discussion of the notion of categorial act, or more specifically categorial intuition. In the second part, Husserl deals with the descriptive eidetic laws that are based on pure descriptive essences or concepts, as well as with the method of validation required by their general form.
