A person sometimes forms moral beliefs by relying on another person''s moral testimony. In this paper I advance a cognitivist normative account of this phenomenon. I argue that for a person''s actions to be morally good, they must be based on a recognition of the moral reasons bearing on action. Morality requires people to act from an understanding of moral claims, and consequently to have an understanding of moral claims relevant to action. A person sometimes fails to meet this requirement (...) when she relies on another person''s moral testimony, and so there are moral limits on such reliance. (shrink)

Do citizens have an obligation to obey the law? This book differs from standard approaches by shifting from the language of obedience to that of deference. The popular view that law claims authority but does not have it is here reversed on both counts: law does not claim authority but has it. Though the focus is on political obligation, the author approaches that issue indirectly by first developing a more general account of when deference is due to the view of (...) others. Two standard practices that political theorists often consider in exploring the question of political obligation - fair-play and promise-keeping - can themselves be seen as examples of a duty of deference. In this respect the book defends a more general theory of ethics whose scope extends beyond the question of political obligation to questions of duty in the case of law, promises, fair play and friendship.

In the spirit of James and Dewey, I ask what one might want from a theory of knowledge. Much Anglophone epistemology is centered on questions that were once highly pertinent, but are no longer central to broader human and scientific concerns. The first sense in which epistemology without history is blind lies in the tendency of philosophers to ignore the history of philosophical problems. A second sense consists in the perennial attraction of approaches to knowledge that divorce knowing subjects from (...) their societies and from the tradition of socially assembling a body of transmitted knowledge. When epistemology fails to use the history of inquiry as a laboratory in which methodological claims can be tested, there is a third way in which it becomes blind. Finally, lack of attention to the growth of knowledge in various domains leaves us with puzzles about the character of the knowledge we have. I illustrate this last theme by showing how reflections on the history of mathematics can expand our options for understanding mathematical knowledge. (shrink)

Periodic and unexpected shortages of drugs, biologics, and even medical devices have become commonplace in the United States. When shortages occur, hospitals and clinics need to decide how to ration their available stock. When such situations arise, institutions can choose from several different allocation schemes, such as first-come, first-served, a lottery, or a more rational and calculated approach. While the first two approaches sound reasonable at first glance, there are a number of problems associated with them, including the inability to (...) make fine, individual patient-centered decisions. They also do not discriminate between what kinds of patients and what types of uses may be more deserving or reasonable than others. In this article I outline an ethically acceptable procedure for rationing drugs during a shortage in which demand outstrips supply. (shrink)

Hilbert's program attempts to show that our mathematical knowledge can be certain because we are able to know for certain the truths of elementary arithmetic. I argue that, in the absence of a theory of mathematical truth, Hilbert does not have a complete theory of our arithmetical knowledge. Further, while his deployment of a Kantian notion of intuition seems to promise an answer to scepticism, there is no way to complete Hilbert's epistemology which would answer to his avowed aims.

The idea that there should be no limits on freedom of discussion receives passionate defenses from some of the most thoughtful and eloquent writers in our language, for example, Milton's evidential transparence condition and Mill's condition of equal benefit. My interest lies in exposing the consequences of this view for the derivative value of free discussion. I'm going to be particularly concerned with those instances in which these conditions are problematic.

This stunning paperback volume showcases the winners and best entries for the International Garden Photographer of the Year competition and accompanies a major exhibition at the Royal Botanic Gardens, Kew, in May 2011 and touring the UK and USA thereafter. ‘The contemporary camera maybe a technological marvel but it can’t take photographs, only the photographer can do that. To succeed it involves making an incredible complex of choices and only one chance in the entire history of time to make them (...) as close to perfect as possible. A carefree snap - easy, a composed and considered picture, well, that requires a synergy of skills and perhaps a dash of genius. So that's why this album is such a treat to revel in, its a feast of the worlds best gardens, gardeners, the plants and animals growing and living in them in the very best photographic forms. The images will 'wow' you, make you wish you had been there, wish it was your garden in the picture or wish you had squeezed the button. It’s a testament to a huge array of skills and a catalogue of remarkable beauty’. Chris Packham – BBC Presenter and photographer. (shrink)

In a now famous thought experiment, Frank jackson asked us t0 imagine an omniscient scientist, Mary, who is coniincd in a black-and-white room and then released into the world 0f color . Assuming that she is omniscicnt in respect of all physical facts—roughiy, all the facts available to physics and all the facts that they in turn Hx or determine-physicalism would suggest that there is no new fact Mary can discover after emancipation; physicalism holds that all facts are physical in (...) the relevant sense . Yet we cannot help but feel that coming out of that room would be an occasion of dramatic enlightenment and, in particular, an occasion for learning facts to do with how red or yellow or blue 100ks or, as it is usually said, with what it is like t0 sec red or yellow or blue. Many in the black-and—whit<—: room knew all the physical facts about the world, where these may be taken to include three sorts of color facts: objcctual facts, as to what surface colors different objects have, assuming as I shall do throughout—that colors are properties of objects; intentional facts, as to which colors different objects 0r apparent objects are represented as having in the subjc-:ct’s experience, rightly or wrongly; and nonintentional facts, about what such color experiences are like in their effects on subiccts—wh<—:ther they are comforting, or arousing, or whatever. But, according to the argument, Mary didn’t know how any color looks or, equivalently, what color experience is like in itself, not just in its effects O1'1 subjects.

Can it make sense for someone who appreciates the explanatory power of modern science to continue believing in a traditional religious account of the ultimate nature and purpose of our universe?

Pettit presents a selection of essays touching upon metaphysics, philosophical psychology, and the theory of rational regulation. The first part of the book discusses the rule-following character of thought. The second considers how choice can be responsive to different sorts of factors, while still being under the control of thought. The third examines the implications of this view of choice and rationality for the normative regulation of social behavior.
