Those who know Raymond Frey and myself only through our writings usually suppose that we

must be on very bad terms, and were doubtless expecting a very acrimonious debate to open

the Wolfson Lecture Series in Oxford in the autumn of 1986. In fact we are friends and

sometime colleagues. It is clear that we disagree on many issues, not least the treatment of

animals, but we don’t necessarily disagree for the reasons and in the ways that others sometimes

suppose. We are both opposed to irrationalism, to the fashionable doctrine that there can be

no moral or other arguments worth considering. We are both opposed to the related dogma

of amoralism, the idea that no moral conclusions are worth taking seriously, whether because

there are no ‘moral facts’ or because no one ever ‘really’ acts morally or for moral reasons.
