H.P. Grice is known principally for his influential contributions to the philosophy of language, but his work also includes treatises on the philosophy of mind, ethics, and metaphysics--much of which is unpublished to date. This collection of original essays by such philosophers as Nancy Cartwright, Donald Davidson, Gilbert Harman, and P.F. Strawson demonstrates the unified and powerful character of Grice's thoughts on being, mind, meaning, and morals. An introductory essay by the editors provides the first overview of Grice's work.

Consider the proposition, “Neither the motion of a body nor the action of a force affects space and time themselves”. We rejected this proposition when, in accepting the general theory of relativity, we accepted that the movement of a body or the action of a force affects the curvature of space-time. Compare the following proposition: “p and if and only if or ”. We think this is logically true; at least, most of us do. Some don’t, on empirical grounds—claiming that (...) we should interpret quantum mechanics as showing that the left-hand side can be true when the right-hand side is false. The idea is that the motions of bodies and actions of forces not only affect space-time relations, they also, as it were, affect logical relations as well. I think evidence from quantum mechanics—like empirical evidence generally—cannot possibly show that the equivalence fails to hold. I am convinced that I know a priori that p and if and only if or. My aim here is to explain the basis of this conviction. (shrink)

In the keynote essay, David Chalmers proposes that we explain consciousness by a non-reductive theory of experience which adds new basic principles to the laws of nature. This essay endorses Chalmers’ proposal but argues -- contrary to Chalmers -- that the principles of such a theory interfere with purely physical laws, since the principles entail violations of physical conservation laws. The essay argues that the qualified incorrigibility of the mental nonetheless provides compelling reason to opt for a non-reductive theory.

Reasons and reasoning were central to the work of Paul Grice, one of the most influential and admired philosophers of the late twentieth century. In the John Locke Lectures that Grice delivered in Oxford at the end of the 1970s, he set out his fundamental thoughts about these topics; Aspects of Reason is the long-awaited publication of those lectures. This immensely rich work, powerfully evocative of the mind of its author, will refresh and illuminate discussions in many areas of contemporary (...) philosophy. (shrink)

When is an indirect report of what a speaker meant correct? The question arises in the law. The Contract Law case of Spaulding v. Morse is a good example. Following their 1932 divorce, George Morse and Ruth Morse entered into a trust agreement in 1937 for the support of their minor son Richard. In that agreement, George promised to “pay to [Spaulding as] trustee in trust for his said minor son Richard the sum of twelve hundred dollars per year, payable (...) in equal monthly installments on the first day of each month until the entrance of Richard D. Morse into some college, university or higher institution of learning beyond the completion of the high school grades, and thereupon, instead of said payments, amounting to twelve hundred dollars yearly, he shall and will then pay to the trustee payments in the sum of twenty-two hundred dollars per year for a period of said higher education but not more than four years.” Richard graduated from high school on February 5, 1946 and, in the post-WWII continuation of the draft, was inducted into the army the following day. The question in the case is whether George, by the words of the trust agreement, meant that he would pay $1,200 per year for Richard’s support while he was in the army. Is that a correct indirect report of what George meant?The explanation I offer assumes Gricean analysis of speaker meaning, and it emphasizes the role of speaker meaning typically plays in solving coordination problems. A coordination problem is a situation “in which each person wants to participate in a group action but only if others also participate.” A classic example is a political protest: “each person might want to take part in an antigovernment protest but only if there are enough total protesters to make arrests and police repression unlikely.” Coordination problems arise in more mundane settings as well – in Spaulding v. Morse, for example. Ruth and George want to mutually agree on Richard’s support: Ruth wants to commit to an arrangement only if George does, and vice versa for George. In 1937, George and Ruth solved the problem through speaker meaning. By signing the trust agreement, George, with Ruth as his audience, meant that he obligated himself to a particular support agreement. When Ruth signed, she, with George as her audience, meant that she accepted the agreement. In general, parties often solve coordination problems through speaker meaning. If, for example, enough people can communicate their commitment to participate in the protest to enough people, the protest will take place.The account assigns a central role to the fact that speaker meaning facilitates coordination by creating relevant common knowledge. Common knowledge is “the recursive belief state in which A knows X, B knows X, A knows that B knows X, B knows that A knows X, ad infinitum.” Common knowledge facilitates coordination: “Actors coordinate when they have evidence for common knowledge, and refrain from coordinating when they do not.”.

There is now a body of evidence suggesting that the occurrence and course of schizophrenia are affected by a variety of environmental factors. _The Environment of Schizophrenia_ draws upon our knowledge of these factors in order to design innovations that will decrease its incidence and severity, while enhancing the quality of life for sufferers and their relatives. Examining environmental forces operating at the individual, domestic and broad societal levels, Richard Warner proposes feasible interventions such as: * education about obstetric risks (...) * marketing effective psychosocial treatments * business enterprises set up to employ people with mental illness * cognitive-behavioral therapy for psychosis The Environment of Schizophrenis suggests practical ways to create a better world for those who suffer from this serious illness and for those who are close to them. It will prove fresh and stimulating reading for mental health managers and policy makers, as well as psychiatrists, clinical psychologists, mental health advocates, and communications specialists.
