Abstract

This thesis argues that Heidegger’s accounts of practice and temporality in Being and Time are inseparable, and demonstrates the importance of temporality for contemporary dialogues between Heideggerian phenomenology and cognitive science. It proposes that enactive and action-oriented models of cognition are best suited to engaging with a Heideggerian view of the temporality of practice, and will benefit from the latter’s capacity to explain the purposive self-concern, possibility-directedness, and varying complexity of cognition in richly temporal terms. I begin by showing that Heidegger’s account places temporality and practice in a complex reciprocity in which each fundamentally shapes and permeates the other. The Heidegger of Being and Time conceptualises practice as fundamentally temporal and temporality as intrinsically purposive, meaning that we cannot adequately understand or utilise his analysis of either structure without acknowledging the role of the other. In outlining and defending this reading, I draw out two characteristics of Heidegger’s model of temporality; these features, which affect and are affected by the interconnection of temporality and purposiveness, are an inherent connection to the self-concern of the entity and an emphasis upon a radically indeterminate futurity. I then consider which contemporary approaches in cognitive science represent the most promising interlocutors for this temporality-oriented Heideggerian perspective. After rejecting selected in principle objections to the pursuit of a collaborative, rather than primarily critical, dialogue between Heideggerian phenomenology and cognitive science, I put forward two candidates for participation in a ‘temporality-oriented Heideggerian cognitive science’: the enactivist tradition and Michael Wheeler’s model of cognition. I set out each approach’s connections to Heideggerian thought (which involves arguing for as-yet unexplored links as well as defending existing ones) before showing how and why a Heideggerian conception of temporality can be integrated into both. I suggest that the structures of a Heideggerian model of temporality already resonate with and operate in enactivists’ and Wheeler’s analyses of cognition, and outline how I think each framework benefits from explicitly taking up and developing these connections. Rather than ultimately choosing one of these perspectives over the other, I conclude by proposing that they cooperate with one another. A Heideggerian conception of temporality opens up a space for enactivism and Wheeler’s approach to contribute distinct and complementary insights in the pursuit of a collaborative temporality-oriented Heideggerian cognitive science.
