If a man's aspirations towards a righteous life are serious.. .if he earnestly and sincerely seeks a righteous life, his first act of abstinence is from animal food, because, not to mention the excitement of the passions produced by such food, it is plainly immoral, as it requires an act contrary to moral feeling, i. e., killing - and is called forth only by greed.
Leo TolstoyIt is a rude feeling, because it is natural only to people standing on the lowest level of morality, and expecting from other nations such outrages as they themselves are ready to inflict.
Leo TolstoyThe wrongfulness, the immorality of eating animal food has been recognized by all mankind during all the conscious life of humanity. Why, then have people generally not come to acknowledge this law? The answer is that the moral progress of humanity is always slow; but that the sign of true, not casual Progress, is in uninterruptedness and its continual acceleration. And one cannot doubt that vegetarianism has been progressing in this manner
Leo TolstoySo long as people do not consider all men as their brothers and do not consider human life as the most sacred thing, which rather than destroy they must consider it their first and foremost duty to support; that is so long as people do not behave towards one another in a religious manner, they will always ruin one another's lives for the sake of personal gain.
Leo Tolstoy
