Duration is not a test of true or false.

We say that the truth will make us free. Yes, but that truth is a thousand truths which grow and change.

To love truth for truth's sake is the principal part of human perfection in this world, and the seed-plot of all other virtues.

Truth forever on the scaffold, Wrong forever on the throne, Yet that scaffold sways the future.

Man's passion for truth is such that he will welcome the bitterest of all postulates so long as it strikes him as true.

If truth is a value it is because it is true and not because it is brave to speak it.

To believe fully and at the same moment to have doubts is not at all a contradiction: it presupposes a greater respect for truth, an awareness that truth always goes beyond anything that can be said or done at any given moment.

To be mistaken is a misfortune to be pitied; but to know the truth and not to conform one's actions to it is a crime which Heaven and Earth condemn.

The smallest atom of truth represents some man's bitter toil and agony; for every ponderable chuck of it there is a brave truth-seeker's grave upon some lonely ash-dump and a soul roasting in hell.

Indeed, the dictum that truth always triumphs over persecution, is one of those pleasant falsehoods which men repeat after one another till they pass into commonplaces, but which all experience refutes.
