If, then, I were asked for the most important advice I could give, that which I considered to be the most useful to the men of our century, I should simply say: in the name of God, stop a moment, cease your work, look around you.
Leo TolstoyThe recognition of the sanctity of the life of every man is the first and only basis of all morality.
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.
