It is not my purpose here to discuss the question of vegetarianism, or to meet the objections that may be urged against it; though it must be admitted that of these objections not one can withstand a loyal and scrupulous inquiry. I, for my part, can affirm that those whom I have known to submit themselves to this regimen have found its result to be improved or restored health, marked addition of strength, and the acquisition by the mind of a clearness, brightness, well-being, such as might follow the release from some secular, loathsome, detestable dungeon. [...] 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.
