Abstract
On what I will call the No Subject view, there is a sense in which one may be aware of a thought, conceived as an event in one's stream of consciousness, without being aware of oneself thinking something. Philosophical work on the delusion of thought insertion is one of the areas in which the No Subject view has been highly influential: the view has framed what, in the philosophy of mind, has become the standard interpretation of the delusion. Here I want to present a challenge to the No Subject view, developing from reflection on the ontology of thinking. I will also consider how, if the standard interpretation fails, we are to understand thought insertion. In particular, I will suggest that we should question the widespread assumption that understanding the delusion has to be a matter of making sense of it.
