Happiness of any given life is to be measured, not by its joys and pleasures, but by the extent to which it has been free from suffering-from positive evil.
I turn to right and left, in all the earth I see no signs of justice, sense or worth: A man does evil deeds, and all his days Are filled with luck and universal praise; Another's good in all he does - he dies A wretched, broken man whom all despise.
Man has reason, discrimination and free-will such as it is. The brute has no such thing. It is not a free agent, and knows no distinction between virtue and vice, good and evil. Man, being a free agent, knows these distinctions, and when he follows his higher nature, shows himself far superior to the brute, but when he follows his baser nature can show himself lower than the brute.
Every man should be responsible to others, nor should any one be allowed to do just as he pleases; for where absolute freedom is allowed, there is nothing to restrain the evil which is inherent in every man.
The Tao doesn't take sides; it gives birth to both good and evil. The Master doesn't take sides; she welcomes both saints and sinners. The Tao is like a bellows: it is empty yet infinitely capable. The more you use it, the more it produces; the more you talk of it, the less you understand. Hold on to the center.
You do not settle whether an argument is justified by merely showing that it is of some use. The distinction is not between useful and useless experiments but between barbarous and civilized behaviour. Vivisection is a social evil because if it advances human knowledge, it does so at the expense of human character.
Do not resist the evil-doer and take no part in doing so, either in the violent deeds of the administration, in the law courts, the collection of taxes, or above all in soldiering, and no one in the world will be able to enslave you.
