Subjects have various ways of thinking about themselves. Here are three examples: a subject can think of herself under an appropriate description (the hiker), d.

Cartesians and Lichtenbergians have diverging views of the deliverances of introspection. According to the Cartesians, a rational subject, competent with the relevant concepts, can come to know that he or she thinks – hence, that he or she exists – on the sole basis of his or her introspective awareness of his or her conscious thinking. According to the Lichtenbergians, this is not possible. This paper offers a defence of the Lichtenbergian position using Peacocke and Campbell's recent exchange on Descartes'scogitoas (...) a framework for discussion. A thought-experiment will be presented involving two communities with radically different conceptions of the metaphysics of the self. The purpose of the thought-experiment is to suggest that a substantive metaphysical thesis, whose truth cannot be a priori known, is presupposed by any justified transition from one's introspective awareness of a certain mental activity to the self-ascription of that activity.

Thinking about oneself as a subject leaves unanswered fundamental questions about one’s identity as an object: about which thing one is, about what kind of thing one is, and about whether one exists at all. I put forward a new way of thinking about these questions by outlining the subject-as-object problem, a problem for inquiry directed at oneself qua subject. I argue that the source of the problem lies in the relationship between a basic precondition for inquiry – that something (...) be present – and a framework that enables us to conceive of ourselves as inquirers in an objective world – the framework of objectivity. Once the problem is recognized, we can explain why there is always room for questions about one’s identity in response to any account of oneself and one’s relation to the world. (shrink)
