Delivered at Conway Hall 28 November 1972. Chaired by Sir Jonathan Miller Professor Sir Edmund Leach.
There are strong arguments to support the scientific and Darwinian view of man as differing from other animals only in degree, not in kind. However, even if this view is correct, the degree-differences are so great that the behaviour of, for example, the higher mammals cannot be taken as a guide to understanding human behaviour. Also, we have a need to believe that we are generically different from other animals; and our sense of moral norms and moral responsibility are certainly unique to us.
