How came the bodies of animals to be contrived with so much art, and for what ends were their several parts? Was the eye contrived without skill in Opticks, and the ear without knowledge of sounds?...and these things being rightly dispatch’d, does it not appear from phænomena that there is a Being incorporeal, living, intelligent...?

An object that is at rest will tend to stay at rest. An object that is in motion will tend to stay in motion.

Plato is my friend, Aristotle is my friend, but my greatest friend is truth.

Therefore to the same natural effects we must, as far as possible, assign the same causes.

Ax: 100 Every thing doth naturally persevere in yt state in wch it is unlesse it bee interrupted by some externall cause, hence... [a] body once moved will always keepe ye same celerity, quantity & determination of its motion.

I do not think that this [the universe] can be explained only by natural causes, and are forced to impute to the wisdom and ingenuity of an intelligent.
