I consider my greatest accomplishment to be lifelong celibacy.

The daily disappearance and the subsequent rise of the sun appeared to many of the ancients as a true resurrection; thus, while the east came to be regarded as the source of light and warmth, happiness and glory, the west was associated with darkness and chill, decay and death. This led to the custom of burying the dead so as to face the east when they rose again, and of building temples and shrines with an opening toward the east. To effect this, Vitruvius, two thousand years ago, gave precise rules, which are still followed by Christian architects.

Every particle of matter is attracted by or gravitates to every other particle of matter with a force inversely proportional to the squares of their distances.

I do not know what I may appear to the world, but to myself I seem to have been only a boy playing on the seashore.

That one body may act upon another at a distance through a vacuum, without the mediation of any thing else, by and through which their action and force may be conveyed from one to another, is to me so great an absurdity, that I believe no man, who has in philosophical matters a compentent faculty of thinking, can ever fall into it.

Are not gross bodies and light convertible into one another; and may not bodies receive much of their activity from the particles of light which enter into their composition? The changing of bodies into light, and light into bodies, is very conformable to the course of Nature, which seems delighted with transmutations.

No being exists or can exist which is not related to space in some way. God is everywhere, created minds are somewhere, and body is in the space that it occupies; and whatever is neither everywhere nor anywhere does not exist. And hence it follows that space is an effect arising from the first existence of being, because when any being is postulated, space is postulated.
