We should not pretend to understand the world only by the intellect. The judgement of the intellect is only part of the truth.

You shall know the truth, and the truth shall make you mad.

Truth is what works.

We have to live today by what truth we can get today and be ready tomorrow to call it falsehood.

It is not because the truth is too difficult to see that we make mistakes... we make mistakes because the easiest and most comfortable course for us is to seek insight where it accords with our emotions - especially selfish ones.

To rise from error to truth is rare and beautiful.

Let the future tell the truth, and evaluate each one according to his work and accomplishments. The present is theirs the future, for which I have really worked, is mine.

Man approaches the unattainable truth through a succession of errors.

Art is the lie that enables us to realize the truth.

The books that help you most are those which make you think that most. The hardest way of learning is that of easy reading but a great book that comes from a great thinker is a ship of thought, deep freighted with truth and beauty.
