There is no such thing as perpetual tranquility of mind while we live here.

The first and fundamental law of Nature, which is, to seek peace and follow it.

This I know; God cannot sin, because his doing a thing makes it just, and consequently, no sin.... And therefore it is blasphemy to say, God can sin; but to say, that God can so order the world, as a sin may be necessarily caused thereby in a man, I do not see how it is any dishonor to him.

And therefore in geometry (which is the only science that it hath pleased God hitherto to bestow on mankind), men begin at settling the significations of their words; which settling of significations, they call definitions, and place them in the beginning of their reckoning.

To understand this for sense it is not required that a man should be a geometrician or a logician, but that he should be mad.

For there are very few so foolish who would not rather govern themselves than be governed by others.
