All the most reasonable teachings of human wisdom concerning justice are summed up in that famous adage: Do unto others that which you would that others should do unto you; Do not unto others that which you would not that others should do unto you. But this rule of moral practice is unscientific: what have I a right to wish that others should do or not do to me? It is of no use to tell me that my duty is equal to my right, unless I am told at the same time what my right is.

For though the law of nature be plain and intelligible to all rational creatures; yet men, being biased by their interest, as well as ignorant for want of study of it, are not apt to allow of it as a law binding to them in the application of it to their particular cases.

that all men may be restrained from invading others' rights, and
from doing hurt to one another, and the law of nature be observed, which willeth the peace and preservation of all mankind, the execution of the law of nature is, in that state, put into every man's hands, whereby every one has a right to punish the transgressors of that law to such a degree as may hinder its violation: for the law of nature would, as all other laws that concern men in this world, be in vain, if there were nobody that in the state of nature had a power to execute that law, and thereby preserve the innocent, and restrain offenders.

The state of nature has a law of nature to govern it, which obliges every one: and reason, which is that law, teaches all mankind, who will but consult it, that being all equal and independent, no one ought to harm another in his life, health, liberty, or possessions:

Any man may easily do harm, but not every man can do good to another.

For the Lawes of Nature (as Justice, Equity, Modesty, Mercy, and (in summe)doing to others, as wee would be done to,) of themselves, without the terrour of some Power, to cause them to be observed, are contrary to our naturall Passions, that carry us to Partiality, Pride, Revenge, and the like. And Covenants, without the Sword, are but Words, and of no strength to secure a man at all.

"The morality which emerges from the observation of the whole animal kingdom may be summed up in the words: "Do to others what you would have them do to you in the same circumstances. And it adds: "Take note that this is merely a piece of advice; but this advice is the fruit of the long experience of animals in society. And among the great mass of social animals, man included, it has become habitual to act on this principle. Indeed without this no society could exist, no race could have vanquished the natural obstacles against which it must struggle."

"People have gotten used to living a botched-up life — to be anxious, insecure, hateful, jealous, and in various states of unpleasantness through the day — slowly humanity has begun to see it as normal. None of these things are normal. These are abnormalities. Once you accept them as part of life they become normal because the majority has joined the gang of unpleasantness. They are all saying, "Unpleasantness is normal. Being nasty to each other is normal. Being nasty to myself is normal." Someone trusted that you would be doing good things at least to yourself and said, "Do unto others what you do unto yourself." I am telling you, never do unto others what you are doing to yourself! By being with people, I know what they are doing to themselves is the worst thing. Fortunately, they are not doing such horrible things to others. Only once in a while they are giving a dose to others, but to themselves they are giving it throughout the day."

Don't do unto others what you don't want done unto you.
