Upshot: Chemero provides a modern re-interpretation of Gibson’s ecological psychology and his affordance concept that is more coherent than the original and in line with antirepresentationalist, dynamical theories in embodied cognitive science. He argues for a radical embodied cognitive science, in which ecological and enactive approaches join forces against the more watered-down, mainstream embodied cognitive science that still maintains traditional commitments to representationalism and computationalism. He also defends a special version of realism, entity realism, which many constructivists might not find entirely convincing, but which is nevertheless more or less compatible with enactive theories of embodied cognition.

Enactivism maintains that the mind is not produced and localized inside the head but is distributed along and through brain-body-environment interactions. This idea of an intrinsic relationship between the agent and the world derives from the classical phenomenological investigations of the body (Merleau-Ponty in particular). This paper discusses similarities and differences between enactivism and Jean-Paul Sartre’s phenomenology, which is not usually considered as a paradigmatic example of the relationship between phenomenological investigations and enactivism (or 4E theories in general). After a preliminary analysis of the three principal varieties of enactivism (sensorimotor, autopoietic and radical), I will present Sartre’s account of the body, addressing some key points that can be related to the current enactivist positions: perception-action unity, anti-representationalism, anti-internalism, organism-environment interaction, and sense-making cognition. Despite some basic similarities, enactivism and Sartre’s phenomenology move in different directions as to how these concepts are developed. Nevertheless, I will suggest that Sartre’s phenomenology is useful to the enactivist approaches to provide a broader and more complete analysis of consciousness and cognition, by developing a pluralist account of corporeality, enriching the investigation of the organism-environment coupling through an existentialist perspective, and reincluding the concept of subjectivity without the hypostatisation of an I-subject detached from body and world.

Clinical reasoning is essential in physical therapy practice. Instrumental approaches and more recent narrative approaches to clinical reasoning guide physical therapists in their understanding of the patient’s movement disturbances and help them to plan strategies to improve function. To the extent that instrumental and/or narrative models of clinical reasoning represent impairments as mere physical disturbances, we argue that such models remain incomplete. We draw on a phenomenologically inspired approach to embodied cognition (termed “enactivism”) to suggest that the dynamics of lived bodily engagement between physical therapist and patient contribute to and help to constitute the clinical reasoning process. This article outlines the phenomenologically informed enactive perspective on clinical reasoning, with special reference to clinical work that addresses impairments as sequelae of neurological diseases.
