The purpose of this article is to examine the close connection between the science of psychology, especially Gestalt psychology, and phenomenology in the thinking of twentieth-century French philosopher and phenomenologist Maurice Merleau-Ponty. This philosopher established his own philosophy under the influence of significant advances in psychology on the one hand, and also under the influence of Husserl's phenomenology. Understanding the philosophy of this philosopher without understanding the close relationship between psychology and phenomenology, especially in the matter of the living body, will lead to a lot of misunderstanding in reading his views. In this article, we tried to show this close relationship in the thought of this thinker. We know, of course, that he criticized Husserl's phenomenology and Gestalt psychology, and argued that psychology fails to understand the nature of the human mind.
