The mind wants the world to return its love, or its awareness; the mind wants to know all the world, and all eternity, and God.

Mind is a most delicate evidence. Not a soul has seen it yet.

Outside, among your fellows, among strangers, you must preserve appearances, a hundred things you cannot do; but inside, the terrible freedom!

It is the mind which creates the world about us, and even though we stand side by side in the same meadow, my eyes will never see what is beheld by yours, my heart will never stir to the emotions with which yours is touched.

The limits of thought are not so much set from outside, by the fullness or poverty of experiences that meet the mind, as from within, by the power of conception, the wealth of formulative notions with which the mind meets experiences.

The understanding, like the eye, whilst it makes us see and perceive all things, takes no notice of itself; and it requires art and pains to set it at a distance and make it its own subject.

The mind is its own place, and in itself Can make a heaven of hell, a hell of heaven.

The mind is a dangerous weapon, even to the possessor, if he knows not discreetly how to use it.

Order and reason, beauty and benevolence, are characteristics and conceptions which we find solely associated with the mind of man.

We are less justified in saying that the thinking life of humanity is a miraculous perfectioning of animal and physical life than that it is an imperfection in the organization of spiritual life as rudimentary as the communal existence of protozoa in colonies.
