Vegetarian: Yes, if you like to express it so; and it is still more evident that men have that tendency. But the question is whether the tendency is rightly interpreted as giving a sanction to flesh-eating. For flesh-eating, as we use the term, means the breeding, destroying, and devouring of highly-organised mammals, and is a very different thing from the egg and lizard hunting in which the monkeys sometimes indulge. If you would confine your flesh-eating to a few insects and nestlings, you would have a better right to quote the example of the apes.
Has flesh-eating been a necessary step in man's progress? Without access to the flesh-pots, it has been asked, would not the race have remained in the groves with the orangs and the gorillas? I do not see that vegetarians need concern themselves to answer such speculations, which, interesting though they are, do not bear closely on the present issue. For though, as we have seen, the testimony of the past is in favour of a frugivorous origin, the problem of the present is one which we are free to solve without prejudice, and whether the past use of flesh food, by a portion of the world's inhabitants, has helped or hindered the true development of man is a matter for individual judgment. We may have our own opinion about it. But what we are concerned to prove is that flesh-eating can offer no advantages to us now.
THE APPEAL TO NATURE
Of the many dense prejudices through which, as through a snowdrift, vegetarianism has to plough its way before it can emerge into the field of free discussion, there is none perhaps more inveterate than the common appeal to "Nature." A typical instance of the remarkable misuse of logic which characterises such argument may be seen in the anecdote related by Benjamin Franklin, in his "Autobiography," of the incident which induced him to return, after years of abstinence, to a flesh diet. He was watching some companions sea-fishing, and observing that some of the fish caught by them had swallowed other fish, he concluded that, "If you eat one another, I don't see why we may not eat you"—a confusion of ichthyology and morals which is ludicrous enough as narrated by Franklin, but not essentially more foolish than the attempt so frequently made by flesh-eaters to shuffle their personal responsibility on to some supposed "natural law."
But let the carnivorous anthropologist speak for himself:
Anthropologist: Now, understand me! I think this vegetarianism is well enough as a sentiment; I fully appreciate your aspiration. But you have overlooked the fact that it is contrary to the laws of Nature. It is beautiful in theory, but impossible in practice.
Vegetarian: Indeed! That puts me in an awkward position, as I have been practising it for twenty years.
Anthropologist: It is not the individual that I am speaking of, but the race. A man may practise it perhaps; but mankind cannot do so with impunity.
Vegetarian: And why?
