I had rather be an oyster than a man, the most stupid and senseless of animals.

A man needs no arguments to make him discern and approve what is beautiful: it strikes at first sight, and attracts without a reason. And as this beauty is found in the shape and form of corporeal things, so also is there analogous to it a beauty of another kind, an order, a symmetry, and comeliness in the moral world. And as the eye perceiveth the one, so the mind doth by a certain interior sense perceive the other, which sense, talent, or faculty, is ever quickest and purest in the noblest minds.

To be is to be perceived

Nothing can be plainer, than that the motions, changes, decays, and dissolutions, which we hourly see befall natural bodies (and which is what we mean by the course of nature), cannot possibly affect an active, simple, uncompounded substance: such a being therefore is indissoluble by the force of nature, that is to say, the soul of man is naturally immortal.

Did men but consider that the sun, moon, and stars, and every other object of the senses, are only so many sensations in their minds, which have no other existence but barely being perceived, doubtless they would never fall down and worship their own ideas; but rather address their homage to that eternal invisible Mind which produces and sustains all things.

How often must I repeat, that I know or am conscious of my own being; and that I myself am not my ideas, but somewhat else, a thinking, active principle that perceives, knows, wills, and operates about ideas?
