It is hard to take a stand against the errors of your age; if you resist them, you remain alone; if you allow yourself to be seduced by them, it is neither to your honor nor to your joy.
If the wise were not mistaken, fools should despair.
Obscurantism itself does not only mean preventing the spread of truth, light and good, but also promoting lies and falsehood.
Only by being wrong do you sometimes find the right path.
The truth...the God of the free man.
The lie... a truth with crooked roots.
The essence of truth is freedom.
An honest man remains in all circumstances the inalienable right to openly confess his error.
Truth is not born and emerges only from the churning of opposing ideas.
Diamonds are found only in the dark recesses of the earth, and truths are found only in the depths of thought.

It is the usual fate of new truths to begin as heresies and end as superstitions.
All great truths are self-evident truths. But not all self-evident truths are great truths.
The search for truth is the deep aspiration of our soul, our intelligence and our feeling.

There is and will be no society in which new truths are not imposed with struggle and do not claim courage.
What would a world look like in which interpretations were unique and given once and for all? What truths are so incontrovertible that they do not incite contradictory discussions?... Only tautologies have such virtues, and only axioms have such obvious demonstrative power. But the axiomatic world is poor, general and abstract.
When one has become the possessor of the whole truth, the only authentic truth, would it not be unforgivable if he kept it to himself, leaving his less fortunate fellows to follow their crooked ways instead of guiding them and treat them?
Truth is proven only by its effectiveness.
Truth is that which is necessary to every man's life: but no man can obtain or buy. Each man will have to create it deep in his life; otherwise it crashes. To live without truth is impossible. Perhaps the truth is life itself.
What is truth but a life for an idea?
A witness to the truth is a man whose life is deeply initiated in inner struggles, in fear and trembling, in sensations, in the miseries of the soul, in moral pains.
