Abstract

David Hume's early philosophy appeals to fiction and artifice to explain several important features in our cognitive and social activity. In this dissertation, I develop a typology of Humean fictions and artifices to clarify and render his account consistent. In so doing, I identify a special class of fictions I divide into natural fictions and natural artifices. I argue that this special class of fictions represents a significant break with prior English-speaking philosophers, such as Francis Bacon and John Locke, in so far as these fictions and artifices of the imagination are recognized as natural, irresistible, and pragmatically useful in human cognition and social activity. That fictions and artifices are naturally generated by the imagination in epistemic and moral contexts, I argue, is a watershed discovery in the history of philosophy. Indeed, it is a philosophical conclusion that poses serious, perhaps fatal, problems for philosophers who espouse thoroughgoing realist positions. More broadly, Hume's pursuit of applying the experimental method to the moral subject reveals that human nature is mightily governed by the imagination, and that fictions and artifices are ubiquitous across the domains of science, morality, theology, logic, mathematics, and philosophy. For that reason, I suggest Hume ought to be recognized as a central figure in the history of philosophical fictionalism. Specifically, via a comparative analysis of Hume and Hans Vaihinger, I make the case that Hume functions as a vital link between Hobbes, Berkeley, and Kant in the development of early modern fictionalism.
