Reason is natural revelation, whereby the eternal father of light, and fountain of all knowledge, communicates to mankind that portion of truth which he has laid within the reach of their natural faculties: revelation is natural reason enlarged by a new set of discoveries communicated by God. . . .

The mind being, as I have declared, furnished with a great number of the simple ideas conveyed in by the senses, as they are found in exterior things, or by reflection on its own operations, take notice, also, that a certain number of these simple ideas go constantly together... which, by inadvertency, we apt afterward to talk of and condier as one simple idea.

Man is not permitted without censure to follow his own thoughts in the search of truth, when they lead him ever so little out of the common road.

These two, I say, viz. external material things, as the objects of SENSATION, and the operations of our own minds within, as the objects of REFLECTION, are to me the only originals from whence all our ideas take their beginnings.

There cannot any one moral rule be proposed whereof a man may not justly demand a reason. Every man has a property in his own person. This nobody has any right to but himself. The people cannot delegate to government the power to do anything which would be unlawful for them to do themselves.

Habits wear more constantly and with greatest force than reason, which, when we have most need of it, is seldom fairly consulted, and more rarely obeyed

All men by nature are equal in that equal right that every man hath to his natural freedom, without being subjected to the will or authority of any other man; being all equal and independent, no one ought to harm another in his life, health, liberty or possessions.
