Abstract: Husserl views the collapse of reason and philosophy crisis as the root of modern science crisis in Europe,and applies the method of phenomenological Epoché (detachment) to building up the so-called scientific philosophy;thereby he provides the philosophical cure for natural science on the basis of “life-world” which is established with pure reason.However,in this theory the revelations coexist with the drawbacks.To overcome the drawbacks,he should replace the intuition of “viewing” with the practical thinking mode and replace the method of phenomenology with the method of history and logic.

Key words: Husserl, natural science, phenomenology, life-world, philosophical cure
