You and I are watching a spider crawl across the carpet. We are both aware of the spider, and aware that both are so aware. We are jointly attending to it. This collection of essays addresses a bewildering array of questions that arise regarding the notion of joint attention. How should joint attention be characterised in adults? In particular, how can we articulate the sense in which it is plausible to say that nothing is hidden from either participant in cases of joint attention? What is the relationship between joint attention and the much discussed phenomenon of common, or mutual, knowledge? What account should be given of the development of the capacity for joint attention in children (and in non-human primates)? At what age is it correct to say that children are engaging in episodes of full blown joint attention? Relatedly, what is the relation between joint attention and pointing behaviour, gaze following and mutual affect regulation? Why is it that autistic children appear to exhibit a joint attention deficiency, and what might this tell us about autism, or about joint attention itself? Does the capacity for joint attention presuppose an understanding of the notion of attention, or more generally a subject of experience, and if so what is the relation between that understanding and the types of behaviour associated with joint attention? More generally, how does joint attention relate to our understanding of others? Finally, is the capacity for joint attention pivotal for the development of linguistic communication, or perhaps even a sense of objectivity—of the mind independence of the world?

The Body Claim states that a transcendental condition of self-consciousness is that one experience oneself as embodied. The contention of this thesis is that popular arguments in support of the Body Claim are unconvincing. Understanding the Body Claim requires us to have a clear understanding of both self-consciousness and embodied experience. In the first chapter I lay out two different conceptions of self-consciousness, arguing that the proponent of the Body Claim should think of self-consciousness as first-person thought. I point out that since arguments for the Body Claim tend to proceed by stating putative transcendental conditions on self-reference, the proponent of the Body Claim must maintain that there is a conceptual connection between self-consciousness and self-reference. In the second chapter I argue against views, originating from Wittgenstein and Anscombe, which reject this connection between self-consciousness and self-reference. In chapter three I show that a well known principle governing the ascription of content, that which Evans calls ‘Russell’s Principle’, occupies an ambiguous position with regards to the Body Claim. I argue that Russell’s Principle should be rejected. Chapter four distinguishes between two conceptions of embodied experience: bodily-awareness and bodily self-awareness. I argue that there is no such thing as bodily self-awareness and so it cannot be a transcendental condition of self-consciousness. Chapter five looks at, and finds wanting, arguments for the Body Claim that can be found in the work of Strawson. Chapter six argues that it is a transcendental condition of self-consciousness that one enjoy spatial experience. Chapters seven and eight assess two influential arguments that attempt to complete a defence of the Body Claim: the solidity argument and the action argument. I argue that neither argument is convincing. Although the conclusions are primarily negative, much is learned along the way about the nature of both self-consciousness and embodied experience.
