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.

To explain all nature is too difficult a task for any one man or even for any one age

Physics, beware of metaphysics.

I see I have made my self a slave to Philosophy.

I do not feign hypotheses.

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.

Hypotheses non fingo. I frame no hypotheses.
