It is surely harmful to souls to make it a heresy to believe what is proved.

In the sciences, the authority of thousands of opinions is not worth as much as one tiny spark of reason in an individual man.

Holy Scripture could never lie or err...its decrees are of absolute and inviolable truth.

Nonetheless, it moves.

Their vain presumption of knowing all can take beginning solely from their never having known anything; for if one has but once experienced the perfect knowledge of one thing, and truly tasted what it is to know, he shall perceive that of infinite other conclusions he understands not so much as one.

In questions of science, the authority of a thousand is not worth the humble reasoning of a single individual.

The greatest wisdom is to get to know oneself.
