I THE NATURE OF MAN To understand morals and politics, understand man. Leviathan , 'that mortal god, to which we owe under the immortal God, our peace and ...

Towards the ends of their reviews, Annette Baier and Jean Hampton allow, if only momentarily, the real spectres to surface. Baier writes, ‘Gauthier rightly sees the dangers of exploitation and subjection inherent in a kin-based and affection-dependent morality, so purports to try for something totally different. Even if our moral natures cannot recognize themselves in Gauthier’s version of them, the problem that drives the attempt [for an individualist and unsentimental morality] is a real one, and so far, I think, an (...) unsolved one; unsolved for morality as well as for moral theory.’ Hampton writes, ‘Gauthier will point out that anyone who insists that a human being has objective value must develop a theory that will not only justify that claim but also explain what reason one would ever have for respecting this value. I believe this is a challenge one has no choice but to accept, given what the moral facts are.’. (shrink)

The Logic of Leviathan The Moral and Political Theory of Thomas Hobbes.

This book explores the role of artificial intelligence in the development of a claim that morality is person-made and rational. Professor Danielson builds moral robots that do better than amoral competitors in a tournament of games like the Prisoners Dilemma and Chicken. The book thus engages in current controversies over the adequacy of the received theory of rational choice. It sides with Gauthier and McClennan, who extend the devices of rational choice to include moral constraint. Artificial Morality goes further, by (...) promoting communication, testing and copying of principles and by stressing empirical tests. (shrink)

The 'Evolution of Cooperation' addresses a simple yet age-old question; If living things evolve through competition, how can cooperation ever emerge? Despite the abundant evidence of cooperation all around us, there existed no purely naturalistic answer to this question until 1979, when Robert Axelrod famously ran a computer tournament featuring a standard game-theory exercise called The Prisoner's Dilemma. To everyone's surprise, the program that won the tournament, named Tit for Tat, was not only the simplest but the most "cooperative" entrant. (...) This unexpected victory proved that cooperation - one might even say altruism - is mathematically possible and therefore needs no hidden hand or divine agent to create and sustain it. A great roadblock to the understanding of all sorts of behavior was at last removed. The updated edition includes an extensive new chapter on cooperation in cancer cells and among terrorist organizations. (shrink)
