Introduction: The varieties of enactivism

Just over 25 years ago, Francisco Varela, Evan Thompson and Eleanor Rosch published The Embodied Mind: Cognitive Science and Human Experience (TEM). An ambitious synthesis of ideas from phenomenology, cognitive science, evolutionary biology, Buddhist philosophy and psychology, it attempted to articulate a new research programme: an enactive cognitive science, that would bridge the gap between the empirical study of the mind and the disciplined reflection on our lived experience that characterises phenomenological and Buddhist practices. This enactive approach to the study of mind represented a confluence of several streams of thought whose effect on the cognitive scientific landscape was becoming gradually more pronounced. A vision of cognition as active, embodied, and embedded was beginning to crystalise, and TEM consolidated and further strengthened existing trends. In the intervening years, the theoretical currents that flowed into TEM have only grown stronger within cognitive science and philosophy of mind. As a result, the ‘enactivist’ label has gained in currency, as different combinations of TEM’s main conceptual ingredients have been concocted and presented by different researchers. A consequence of this is the apparent existence of a variety of distinct but overlapping ‘enactivisms’, the relations between which are not always clear. This special issue aims to provide a clearer picture of the enactivist theoretical landscape, some of its distinctive landmarks, and the disputed borders between its main provinces. Each of the papers in this issue takes up and pursues a live theoretical issue for enactivist research, while at the same time shedding light on the conceptual geography of enactivism. In this introduction, we frame these contributions by providing a brief sketch of the streams of thought that flowed into TEM and the origins of enactivism, and the main theoretical channels that have emerged from it.
