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

I do not know when, but I know that many have come in this century to develop arts and sciences, sow the seeds of a new culture that will flourish, unexpected, sudden, just when the power is deluded into believing they have won.

I fought, and therefore, believed in my victory. There is more to the fact that I didn't fear death and preferred a brave death instead of a life of an idiot.

There is one basic cause of all effects.

The soul, in its power, is present in some way in the entire universe, because it apprehends substances which are not included in the body in which it lives, although they are related to it.

I have held and hold souls to be immortal.... Speaking as a Catholic, they do not pass from body to body, but go to paradise, purgatory or hell. But I have reasoned deeply, and, speaking as a philosopher, since the soul is not found without body and yet is not body, it may be in one body or in another, and pass from body to body.

Desire urges me on, while fear bridals me.
