To understand the radical potential of Heidegger’s model of practice, we need to acknowledge the role that temporality plays within it. Commentaries on Heidegger’s account of practical engagement, however, often leave the connection between purposiveness and temporality unexplored, a tendency that persists in the contemporary discourse generated by the interaction between the phenomenological tradition and certain approaches within cognitive science. Taking up a temporality-oriented reading that redresses this can, I want to argue here, reveal new illuminating sites for the intersection between phenomenology and the cognitive sciences, particularly between Heideggerian perspectives and what have become known as enactive approaches to the study of cognition. According to the latter, cognition is an inherently relational process through which the interaction of a living being and its environment generates meaning and, ultimately, a world of significance defined by the cogniser’s self-concern. I will suggest that this emphasis upon the inextricable intertwining of agent and world renders enactive models of cognition particularly congenial to a mutually enriching dialogue with Heidegger’s account of purposiveness, particularly if we read the latter in terms of the temporal framework that Being and Time offers us.
