This paper discusses the notion of embodied knowledge, which is derived from the phenomenology of Maurice Merleau-Ponty. Embodied knowledge is a type of knowledge where the body knows how to act (e.g., how to touch type, how toride a bicycle, etc.). One of the important features of this knowledge is that the body, not the mind, is the knowing subject. Procedures for performance are embodied such that the body knows how to act in a given situation. Embodied knowledge is not confined only to motor skills, but is concerned with the variety of human experiences, all of which share the property of 'doing without representing'. There is no need for representation because there exists a pre-reflective correspondence between body and world. Through examining Merleau-Ponty's notion of body schema, I try to clarify that embodied knowledge is beyond the Cartesian mind-body dualism and requires an embodied view of mind.

The main aim of this article is to revisit Merleau-Ponty's notion of intercorporeality (intercorporéité) and elaborate it as a new theory of social cognition. As is well known, theory of mind has been the central issue in the field of social cognition for more than two decades. In reviewing the basic concepts involved in two major theories (theory theory and simulation theory), I make clear that both theories have been missing the embodied dimension because of their mind–body dualistic supposition. The notion of intercorporeality, in accordance with the recent interaction theory, stresses the role of embodied interactions between the self and the other in the process of social understanding. I develop this notion into two directions and describe the related process of social cognition: one is behavior matching and primordial empathy, the other is interactional synchrony and the sense of mutual understanding. Through these embodied interactions, intersubjective meanings are created and directly shared between the self and the other, without being mediated by mental representations.

The aim of this article is to develop an interaction theory (IT) of social cognition. The central issue in the field of social cognition has been theory of mind (ToM), and there has been debate regarding its nature as either theory-theory or as simulation theory. Insights from phenomenology have brought a second-person perspective based on embodied interactions into the debate, thereby forming a third position known as IT. In this article, I examine how IT can be further elaborated by drawing on two phenomenological notions—Merleau-Ponty's intercorporeality and Kimura's aida. Both of these notions emphasize the sensory-motor, perceptual, and non-conceptual aspects of social understanding and describe a process of interpersonal coordination in which embodied interaction gains autonomy as an emergent system. From this perspective, detailed and nuanced social understanding is made possible through the embodied skill of synchronizing with others.

So long as I maintain the ordinary modes of experience such as walking or eating, the body appears to me as something inseparable from myself. Through and with the body I act in the world, and through and from the body I perceive the world. However, this is not the case in the pathological condition known as depersonalization/ derealization disorder (DD). People with DD frequently claim that their self is disconnected from the body and their bodily actions feel like those of a robot. This symptom raises an important question about the paradigm of the embodied self, which is whether the union of body and self is contingent or not. In this paper, I describe the split between the self and body experienced in DD, then compare it with experiences of the full-body illusion, in which the self is perceived to be located out of the physical body. Through this comparison, it is made clear that the self in DD is not totally disembodied even though the basic sense of self has gone through a qualitative change.
