A groundbreaking discussion of how we can apply the new science of choice architecture to nudge people toward decisions that will improve their lives by making them healthier, wealthier, and more free. Yes, there is such a thing as common sense—and thank goodness for that. At least that's this reader's reaction to Richard Thaler and Cass Sunstein's Nudge, an engaging and insightful tour through the evidence that most human beings don't make decisions in the way often characterized (some would say caricatured) in elementary economics textbooks, along with a rich array of suggestions for enabling many of us to make better choices, both for ourselves and for society. ~ Benjamin M. Friedman of The New York Times

Perhaps everything we think, feel, and do is determined, and humans — like stones or clouds — are slaves to the laws of nature. Would that be a terrible state? Philosophers who take the incompatibilist position think so, arguing that a deterministic world would be one without moral responsibility and perhaps without true love, meaningful art, and real rationality. But compatibilists and semicompatibilists argue that determinism need not worry us. As long as our actions stem, in an appropriate way, from us, or respond in some way to reasons, our actions are meaningful and can be judged on their moral (or other) merit. In this highly original work, Nomy Arpaly argues that a deterministic world does not preclude moral responsibility, rationality, and love — in short, meaningful lives — but that there would still be something lamentable about a deterministic world. A person may respond well to reasons, and her actions may faithfully reflect her true self or values, but she may still feel that she is not free. Arpaly argues that compatibilists and semicompatibilists are wrong to dismiss this feeling — for which there are no philosophical consolations — as philosophically irrelevant. On the way to this bittersweet conclusion, Arpaly sets forth surprising theories about acting for reasons, the widely accepted idea that "ought implies can," moral blame, and more.

In Good and Real, Gary Drescher examines a series of provocative paradoxes about consciousness, choice, ethics, quantum mechanics, and other topics, in an effort to reconcile a purely mechanical view of the universe with key aspects of our subjective impressions of our own existence. Many scientists suspect that the universe can ultimately be described by a simple (perhaps even deterministic) formalism; all that is real unfolds mechanically according to that formalism. But how, then, is it possible for us to be conscious, or to make genuine choices? And how can there be an ethical dimension to such choices? Drescher sketches computational models of consciousness, choice, and subjunctive reasoning—what would happen if this or that were to occur?—to show how such phenomena are compatible with a mechanical, even deterministic universe. Analyses of Newcomb's Problem (a paradox about choice) and the Prisoner's Dilemma (a paradox about self-interest vs. altruism, arguably reducible to Newcomb's Problem) help bring the problems and proposed solutions into focus. Regarding quantum mechanics, Drescher builds on Everett's relative-state formulation—but presenting a simplified formalism, accessible to laypersons—to argue that, contrary to some popular impressions, quantum mechanics is compatible with an objective, deterministic physical reality, and that there is no special connection between quantum phenomena and consciousness. In each of several disparate but intertwined topics ranging from physics to ethics, Drescher argues that a missing technical linchpin can make the quest for objectivity seem impossible, until the elusive technical fix is at hand. ~ Product Description
