For in truth all our justice, morality, all our thoughts and feelings, derive from three or four primordial necessities, whereof the principal one is food. The least modification of one of these necessities would entail a marked change in our moral existence. Were the belief one day to become general that man could dispense with animal food, there would ensue not only a great economic revolution--for a bullock, to produce one pound of meat, consumes more than a hundred of provender--but a moral improvement as well, not less important and certainly more sincere and more lasting than might follow a second appearance on the earth of the Envoy of the Father, come to remedy the errors and omissions of his former pilgrimage. For we find that the man who abandons the regimen of meat abandons alcohol also; and to do this is to renounce most of the coarser and more degraded pleasures of life. And it is in the passionate craving for these pleasures, in their glamour, and the prejudice they create, that the most formidable obstacle is found to the harmonious development of the race.
