Abstract

There are two questions concerning Hume’s doctrine of existence which have not yet found any persuasive answer: What is his argument in favour of the thesis that there is no distinct idea of existence? What are the semantic and metaphysical consequences of this thesis within his philosophical framework? This paper mainly aims to answer question. In order to do that, I will first explain why some reconstructions suggested by interpreters such as Cummins and Bricke are problematic. One of them relies on exegetically dubious presumptions; the other departs too much from Hume’s text. Then, I will offer my own reconstruction that makes maximal use of some principles which are very familiar to Hume’s readers, including the principle stating the similarity between perceptions and their images. After that, I will discuss a potential objection to my reconstruction and make a brief remark on question, arguing that, as opposed to numerous interpreters’ concerns, Hume’s thesis that there is no distinct idea of existence does not by itself prevent him from being able to conceive negative existential propositions.
