"The Vegetarians may confidently reckon that the new perfect man will not kill and devour other animals, nay, will not kill and devour vegetables, if it is cruel and wrong to do so. Should he after serious moral reflection conclude that vegetable life is as sacred as animal, he will doubtless be clever enough to derive plenty of wholesome food from the mineral kingdom; and should he deem it wrong to ravage even this for so vulgar a purpose as filling his belly, he will doubtless be able to nourish himself without devouring anything at all."
