People coming together more or less by accident can have a catalytic effect on each other, so that each achieves more than he or she would have done alone. The Bloomsbury Group--G.E. Moore, Virginia and Leonard Woolf, E.M. Forster, J.M. Keynes, Vanessa and Clive Bell, Lytton Strachey and others--is a famous example. It would be immodest to suggest that the group of vegetarians who were together in Oxford from 1969 to about 1971 can compare with these illustrious figures; yet if the animal liberation movement ever succeeds in transforming our attitudes to other species, the Oxford Vegetarians may one day be seen to have been a significant force.
