All the choir of heaven and furniture of earth - in a word, all those bodies which compose the frame of the world - have not any subsistence without a mind.

If what you mean by the word "matter" be only the unknown support of unknown qualities, it is no matter whether there is such a thing or no, since it no way concerns us; and I do not see the advantage there is in disputing about what we know not what, and we know not why.

I do not deny the existence of material substance merely because I have no notion of it, but because the notion of it is inconsistent, or in other words, because it is repugnant that there should be a notion of it.

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.

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.

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.

We have first raised a dust and then complain we cannot see.
