Husserl - at least in his third intellectual career - was convinced that subject is placed at the heart of philosophy and philosophy is nothing but egology. This Cartesian character makes Husserl one of the greatest figures of modern thought. But in contemporary period, this central ego and, accompanied with that, the modern thought have been challenged by poststructuralists. Because of their focus on psychoanalysis and their priority to other poststructuralist writings, Lacan's argumeats are significant. In this article, at first, (...) we proceed with the Lacan's central idea against the Cartesian subject, and then by explaining Husserl's thoughts we will see what his defence is. Husserl, by phenomenological reduction of natural attitude inherent in natural sciences, places phenomenology in a different dimension and prefers it to other sciences. The process of raising empirical ego to transcendental ego supports such defence. (shrink)
