The Retreat of Reason brings back to philosophy the ambition of offering a broad vision of the human condition. One of the main original aims of philosophy was to give people guidance about how to live their lives. Ingmar Persson resumes this practical project, which has been largely neglected in contemporary philosophy, but his conclusions are very different from those of the ancient Greeks. They typically argued that a life led in accordance with reason, a rational life, would also be (...) the happiest or most fulfilling. By exploring the irrationality of our attitudes to time, identity, and responsibility, Persson shows that the aim of living rationally conflicts not only with the aim of leading the most fulfilling life, but also with the moral aim of promoting the maximization and just distribution of fulfilment for all. The Retreat of Reason challenges some of our most fundamental ideas about ourselves. (shrink)

When Ingmar and I discuss metaphysics or morality, our views are seldom far apart. Hut on the subjects of this paper, rationality and reasons, we deeply disagree.

My topic is the relation between the right and the good. I introduce it by relating some aspects of the debate between various British intuitionists in the first half of the present century. In Principia Ethica G. E. Moore claimed that to be right is to be productive of the greatest good. He wrote ‘This use of “right”, as denoting what is good as a means, whether or not it be also good as an end, is indeed the use to (...) which I shall confine the word’ . By the time he wrote his Ethics he seems to have weakened his position, and offers conduciveness to the good not as a definition of ‘right’ but as an account of the one and only property that makes acts right. Even if it be the only right-making property, conduciveness to the good will not be identical with the right-ness that it makes. (shrink)
