In the first edition of the Logical Investigations, under the influence of Brentano, Husserl describes his position as " descriptive psychology." Husserl analyzes the intentional structures of mental acts and how they are directed at both real and ideal objects. The first volume of the Logical Investigations, the Prolegomena to Pure Logic, begins with a critique of psychologism, that is, the attempt to subsume the a priori validity of the laws of logic under psychology. Husserl establishes a separate field for research in logic, philosophy, and phenomenology, independently from the empirical sciences.

" Pre-reflective self-consciousness " is Shaun Gallagher and Dan Zahavi 's term for Husserl's (1900/1901) idea that self-consciousness always involves a self-appearance or self-manifestation prior to self-reflection. This is one point of nearly unanimous agreement among phenomenologists: "a minimal form of self-consciousness is a constant structural feature of conscious experience. Experience happens for the experiencing subject in an immediate way and as part of this immediacy, it is implicitly marked as my experience."
