The result can be quite new - perhaps a tendency to judge that something we've never conceived of is possible, or to feel sympathy for a trait or a type of person whom we've regarded with indifference or even hostility.

I don't deny that scientific investigation is capable of delivering important truths about nature, but that doesn't stop questions about whether, as it is practiced, science today lives up to its potential for benefiting humanity.

One of the things I want to do in the book is to explore how philosophy can be done in literature. I start doing that in the first chapter, by introducing the idea of "philosophy by showing". What literature/philosophy shows is how to look at some important facets of life in a new way, thus changing the frame in which subsequent philosophical argument proceeds.

Both Proust and Joyce record the ways in which human perspectives can be transformed. In Portrait, Stephen Dedalus is constantly undergoing epiphanies, but their effects are transitory: the new synthetic complex quickly falls apart. Proust's characters, by contrast, often achieve lasting changes of perspective.

If the research agenda reflects "market forces", the problems of the poor are likely to be even more neglected than they already are.

I suspect that any worthwhile exploration of these deep questions about living requires going beyond abstract discussions to the vivid presentation of possibilities. If readers are to be prompted to serious examination of their lives, anatomy isn't enough. We have to be stimulated to imagine, in some detail, what it would be like to live in particular ways.

There's a disciplined erotic component to it, so that the height of sexual contact is the embrace, the modest touch, a relatively chaste kiss. An important passage from the surviving 1942 diary (one I quote in the book) relates this mode of sexual expression to his own life. Mann had returned to his diary for 1927 (one of those he burned) and to his parting from the young man, Klaus Heuser, whom the family had met on holiday and invited to Munich.
