'I never can catch myself at any time without a perception, and never can observe any thing but the perception.' These famous words of David Hume, on his inability to perceive the self, set the stage for JeeLoo Liu and John Perry's collection of essays on self-awareness and self-knowledge. This volume connects recent scientific studies on consciousness with the traditional issues about the self explored by Descartes, Locke and Hume. Experts in the field offer contrasting perspectives on matters such as the relation between consciousness and self-awareness, the notion of personhood and the epistemic access to one's own thoughts, desires or attitudes. The volume will be of interest to philosophers, psychologists, neuroscientists, cognitive scientists and others working on the central topics of consciousness and the self.

Self, person, and identity are among the concepts most central to the way humans think about themselves and others. It is often natural in biology to use such concepts; it seems sensible to say, for example, that the job of the immune system is to attack the non-self, but sometimes it attacks the self. But does it make sense to borrow these concepts? Don’t they only pertain to persons, beings with sophisticated minds, and perhaps even souls? I argue that if we focus on the every-day concepts of self and identity, and set aside loftier concepts found in religion, philosophy, and psychology that are applicable, at most, to humans, we can see that self and identity can be sensibly applied widely in biology.

No word in English is shorter than the word I.' And yet no word is more important in philosophy. When Descartes said I think therefore I am' he produced something that was both about himself and a universal formula. The word I' is called an indexical' because its meaning always depends on who says it. Other examples of indexicals are you,' here,' this' and now.' John Perry discusses how these kinds of words work, and why they express important philosophical thoughts. He shows that indexicals pose a challenge to traditional assumptions about language and thought. Over the years a number of these papers, now included in this book, have sparked lively debates and have been influential in philosophy, linguistics and other areas of cognitive science. With seven new papers, including the previously unpublished What Are Indexicals?,' the present volume expands on an earlier version of this book published in the early nineties. Also included are the well-known papers Frege on Demonstratives,' Cognitive Significance and New Theories of Reference,' Evading the Slingshot,' The Prince and the Phone booth' (coauthored with Mark Crimmins), Fodor on Psychological Explanations' (coauthored with David Israel), and related papers on situation semantics, direct reference, and the structure of belief. This book also includes afterwords written by the author that discuss responses to his work by Gareth Evans, Robert Stalnaker, Barbara Partee, Howard Wettstein and others.

Review Jopling's discussion is carried on with remarkable clarity. His presentation of the diverse philosophical positions is balanced and fair. . . . Self-Knowledge and the Self is a work of excellent, sound scholarship, a most significant contribution. Hazel Barnes, author of Sartre and Flaubert Jopling's book is the most sustained and serious contemporary philosophical reflection on the Delphic injunction Know thyself of which I am aware. Drawing on literature and psychotherapy as well as solid argumentation, it gently but persuasively exposes inadequacies in the individualistic theories of Hampshire, Sartre, and Rorty and sketches the advantages of a more dialogic approach. Ideally, readers should come away not only knowing what it means to know oneself, but also, in some respects, actually knowing themselves better!. William L. McBride, author of Social and Political Philosophy In this impressive survey, Jopling not only provides incisive critiques of the major contemporary theories of self-knowledge but also introduces a significant alternative approach, one that stresses the role of dialogue and communication.

In this essay I examine how we use indexicals. The key function of indexicals, I claim, is to help the audience --- that is the hearers or readers of the utterance with whom the speaker intends to be communicating---to find supplementary channels of information about the object to which the indexical refers. To keep the discussion manageable, I will oversimplify the epistemology of conversation. I ignore the fact that people sometimes lie and sometimes make mistakes. I talk freely about what one learns and the information one gets from an utterance.

In this essay I first review Kaplan’s theory of linguistic character, and then explain and motivate a concept of doxastic character. I then develop some concepts for dealing with the topic of belief retention and then, finally, discuss Rip Van Winkle. I come down on Kaplan’s side with respect to the Frege-inspired strategy, narrowly construed. But I advocate something like the Frege-inspired strategy, if it is construed more broadly. On my view it is remarkably easy to retain a belief, and I think Evans is quite wrong about Rip and Kaplan. The central concept I develop, however, that of an information game, is in the spirit of much of Evans’ work. I also borrow some of his terminology.

In this paper, I shall defend Russell's view that Mont Blanc, with all of its snow elds, is a component part" or constituent of what is actually asserted when one utters Mont Blanc is more than 4000 meters high," and of what one believes, when one believes that Mont Blanc is 4000 meters high. I also claim, however, that a proposition that does not have Mont Blanc as a constituent plays an important role in the assertion and the belief that Mont Blanc is more than 4000 meters high. Taken somewhat out of context, the quotes from Frege and Russell express insights that pull in di erent directions in the contemporary philosophy of language. Behind Frege's remark is the insight that reference is not direct but mediated. When we think and talk about things, our thoughts and words are not in direct contact with the things thought about and talked about. The meanings of our words, and the cognitive roles of our ideas, do not in and of themselves determine their reference. They get at objects via some aspects of..
