This article starts from a reaction on Heidegger’s critiques of Husserl’s conception of the intentionality and his theoretical position, then investigates with greater depth Husserl’s phenomenological method “epoche”, and highlights that the transcendental ego originally is not “an uninterested observer”. For viewing that from the natural to the transcendental attitude the question of “what” is transformed into the question of “how” by no means replaces the question of “what”. Phenomenology basically aims to endow the essence of matter as “what” through a series of reflections on its “how” with boundless meanings. We estimate this new form of “what” as a work of art, and the phenomenological method as an activity of art. This insight is illuminated by Kant when hi in “Critique of Judgment” discusses the possibility of a beautiful object to be obtained through a Reflective Judgment. We see some scholar thinks Heidegger’s authentic phenomenological psychology like an art. The later Husserl shows his mature phenomenological psychology, as he acquires the rich meanings of the essence (“what”) of the transcendental subjectivity as the topics of the pure phenomenological psychology through a series of reflections of the “how” of the Life-world and the transcendental subjectivity. So Husserl’s phenomenological psychology can be understood as a form of art.
