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

But some, besides allegiance to their original error, possess I know not what fanciful interest in remaining hostile not so much toward the things in question as toward their discoverer.

Names and attributes must be accommodated to the essence of things, and not the essence to the names, since things come first and names afterwards.

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

Showing a greater fondness for their own opinions than for truth, they sought to deny and disprove the new things which, if they had cared to look for themselves, their own senses would have demonstrated to them.

Wine is sunlight, held together by water.

In my studies of astronomy and philosophy I hold this opinion about the universe, that the Sun remains fixed in the centre of the circle of heavenly bodies, without changing its place; and the Earth, turning upon itself, moves round the Sun.
