Ideal of Rationality A Defense, Within Reason

The Ideal of Rationality presents an evaluation of all the main varieties of rationalism, in clear and jargon-free language. Different notions of rationality - such as means-end, conception, hedonism, and the evil-avoidance view - are examined and rejected, in favor of the theory that to act rationally is to 'act for the best', a theory Nathanson characterizes as "critical pluralism." Among present-day thinkers whose ideas are scrutinized are Richard Brandt, Bernard Gert, Gilbert Harman, John Kekes, Robert Nozick, Karl Popper, and John Rawls.

Stephen Nathanson is Professor of Philosophy at Northeastern University.
