Abstract: Naturalized phenomenology is the theoretical crystallization of the union of naturalism and phenomenology， and its essence is to integrate the theoretical insights of classical phenomenology into the explanatory framework of naturalism. Although transcendental phenomenology and naturalism have long been in a sharp opposition， the phenomenology of psychology， as a component of phenomenology， has not abandoned the natural attitude and is therefore inherently compatible with naturalism. Consequently， the reasonable approach of naturalized phenomenology can only be the naturalization of phenomenological psychology. At the same time， naturalized phenomenology is essentially a weakened methodological naturalism which reshapes our understanding of nature itself with a non-reductive natural concept， thus providing a broad space for productive dialogue， communication， and exchange between phenomenology and empirical science.
