The beginning, middle, and end of the birth, growth, and perfection of whatever we behold is from contraries, by contraries, and to contraries; and whatever contrariety is, there is action and reaction, there is motion, diversity, multitude, and order, there are degrees, succession and vicissitude.

The stars in the sky are really other suns like our own, around which orbit other planets. (paraphrase)

Time is the father of truth, its mother is our mind.

It may be you fear more to deliver judgment upon me than I fear judgment.

Truth does not change because it is, or is not, believed by a majority of the people.

Perhaps your fear in passing judgement is greater than mine in receiving it.

Magicians can do more by means of faith than physicians by the truth.
