No pleasure is comparable to the standing upon the vantage-ground of truth.
Francis Bacon (1561-1626)

Nothing but truth is lovely, nothing fair.
Nicolas Boileau-Despréaux (1636-1711)

Truth exists, only falsehood has to be invented.
Georges Braque (1882-1963)

But...what an age is this, and what a world is this! that a man cannot live without playing the knave and dissimulation.
Samuel Pepys (1633-1703)

He who would distinguish the true from the false must have an adequate idea of what is true and false.
Benedict Spinoza (1632-1677)

For truth has such a face and such a mien
As to be lov'd needs only to be seen.
John Dryden (1631-1700)

It is one thing to show a man that he is in an error, and another to put him in possession of truth.
John Locke (1632-1704)

Man is imperfect. At times he is more or less of a hypocrite, and then fools say he is moral or immoral. I am not accusing the rich in favour of the masses. Man is the same at the top, at the bottom, in the middle.
Honore de Balzac (1799-1850)

We know the truth, not only by the reason, but by the heart.
Blaise Pascal (1623-1662)
