In Impossibility, John D. Barrow--one of our most elegant and accomplished science writers--argues convincingly that there are limits to human discovery, that there are things that are ultimately unknowable, undoable, or unreachable. Barrow first examines the limits of the human mind: our brain evolved to meet the demands of our immediate environment, and much that lies outside...(展开全部)

Barrow, Professor of Astronomy at the University of Sussex, has written a very engaging and even playful book. He attempts to show how certain "laws" governing "Nature" help us to separate the possible from the impossible....Barrow's book enjoyable, informative, and thought provoking.

A liberal society seeks not to impose a single way of life, but to leave its citizens as free as possible to choose their own values and ends. It therefore must govern by principles of justice that do not presuppose any particular vision of the good life. But can any such principles be found? And if not, what are the consequences for justice as a moral and political ideal? Thes...(展开全部)

Do all questions have answers? How much can we know about the world? Is there such a thing as an ultimate truth? To be human is to want to know, but what we are able to observe is only a tiny portion of what’s “out there.” In The Island of Knowledge, physicist Marcelo Gleiser traces our search for answers to the most fundamental questions of existence. In so doing, he reaches a...(展开全部)

At the centre of modern epistemology lurks the problem of scepticism: how can we know that the forms of our cognition are compatible with the world? How can we state success conditions for knowledge claims without somehow transcending our discursive and fallible nature as knowers? By distinguishing different forms of scepticism, Markus Gabriel shows how all objective knowledge ...(展开全部)

Caspar Hare presents a novel approach to questions of what we ought to do, and why we ought to do it. The traditional way to approach this subject is to begin by supposing a foundational principle, and then work out its implications. Consequentialists say that we ought to make the world impersonally better, for instance, while Kantian deontologists say that we ought to act on u...(展开全部)

Most of us believe that there are limits to the sacrifices that morality can demand of us. We also think that certain types of acts are simply forbidden, even when necessary for promoting the overall good. Here Kagan argues that attempts to defend these sorts of moral limit are inadequate. In thus rejecting two of the most fundamental features of commonsense morality, the book ...(展开全部)
