At last I will devote myself sincerely and without reservation to the general demolition of my opinions.

Nothing is more fairly distributed than common sense: no one thinks he needs more of it than he already has.

The only thing that I know, is that I know nothing

For how do we know that the thoughts which occur in dreaming are false rather than those others which we experience when awake, since the former are often not less vivid and distinct than the latter?

I should consider that I know nothing about physics if I were able to explain only how things might be, and were unable to demonstrate that they could not be otherwise.

If I simply refrain from making a judgment in cases where I do not perceive the truth with sufficient clarity and distinctness, then it is clear that I am behaving correctly and avoiding error.

A state is better governed which has few laws, and those laws strictly observed.
