If you don't want to slip up tomorrow, speak the truth today.

No one is more hated than he who speaks the truth.

All truths are easy to understand once they are discovered; the point is to discover them.

Art is a lie that leads us to the truth.

Man has much power of discourse which for the most part is vain and false; animals have but little, but it is useful and true, and a small truth is better than a great lie.

The Religion that is afraid of science dishonours God and commits suicide. It acknowledges that it is not equal to the whole of truth, that it legislates, tyrannizes over a village of God's empires but is not the immutable universal law. Every influx of atheism, of skepticism is thus made useful as a mercury pill assaulting and removing a diseased religion and making way for truth.

Place yourself in the middle of the stream of power and wisdom which animates all whom it floats, and you are without effort impelled to truth, to right and a perfect contentment.

See now the power of truth; the same experiment which at first glance seemed to show one thing, when more carefully examined, assures us of the contrary.

Time discovers truth.

The perfect way is only difficult for those who pick and choose. Do not like, do not dislike; all will then be clear. Make a hairbreadth difference and heaven and earth are set apart; if you want the truth to stand clear before you, never be for or against. The struggle between "for" and "against" is the mind's worst disease.

If there were only one truth, it wouldn't be possible to do 100 variations on the same theme.

Again, truth should be highly valued; if, as we were saying, a lie is useless to the gods, and useful only as a medicine to men, then the use of such medicines should be restricted to physicians; private individuals have no business with them.

Then the case is the same in all the other arts for the orator and his rhetoric; there is no need to know the truth of the actual matters, but one merely needs to have discovered some device of persuasion which will make one appear to those who do not know to know better than those who know.
