No man's error becomes his own Law; nor obliges him to persist in it.

The Interpretation of the Laws of Nature in a Common-wealth, dependeth not on the books of Moral Philosophy. The Authority of writers, without the Authority of the Commonwealth, maketh not their opinions Law, be they never so true.

... and where men build on false grounds, the more they build, the greater is the ruine.

But if one Subject giveth Counsell to another, to do anything contrary to the Lawes, whether that Counsell proceed from evil intention, or from ignorance onely, it is punishable by the Common-wealth; because ignorance of the Law, is no good excuse, where every man is bound to take notice of the Lawes to which he is subject.

No man is bound by the words themselves, either to kill himselfe, or any other man.

From whence it follows, that were the publique and private interest are most closely united, there is the publique most advanced.

As in the presence of the Master, the Servants are equall, and without any honour at all; So are the Subjects, in the presence of the Soveraign. And though they shine some more, some lesse, when they are out of his sight; yet in his presence, they shine no more than the Starres in presence of the Sun.

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.

And the Science of them, is the true and onely Moral Philosophy. For Moral Philosophy is nothing else but the Science of what is Good, and Evill, in the conversation, and Society of mankind. Good, and Evill, are names that signify our Appetites, and Aversions; which in different tempers, customes, and doctrines of men, are different.

And though this may seem to subtile a deduction of the Lawes of Nature, to be taken notice of by all men;whereof the most part are too busie in getting food, and the rest too negligent to understand; yet to leave all men unexcusable, they have been contracted into one easie sum, intelligble, even to the meanest capacity; and that is, Do not that to another, which thou wouldest not have done to thyselfe; which sheweth him, that he has no more to do in learning the Lawes of Nature, but, when weighing the actions of other men with his own, they seem too heavy, to put them into the other part of the balance, and his own into their place, that his own passions, and selfe love, may adde nothing to the weight; and then there is none of these Laws of Nature that will not appear unto him very reasonable.
