We are not here concerned with hopes or fears, only with truth as far as our reason permits us to discover it.

I believe there exists, & I feel within me, an instinct for the truth, or knowledge or discovery, of something of the same nature as the instinct of virtue, & that our having such an instinct is reason enough for scientific researches without any practical results ever ensuing from them.

Whoever undertakes to set himself up as a judge of Truth and Knowledge is shipwrecked by the laughter of the gods.

But science can only be created by those who are thoroughly imbued with the aspiration toward truth and understanding

In matters of truth and justice, there is no difference between large and small problems, for issues concerning the treatment of people are all the same.

The pursuit of truth and beauty is a sphere of activity in which we are permitted to remain children all our lives.
