We have heard much about the poetry of mathematics, but very little of it has as yet been sung. The ancients had a juster notion of their poetic value than we. The most distinct and beautiful statements of any truth must take at last the mathematical form. We might so simplify the rules of moral philosophy, as well as of arithmetic, that one formula would express them both.

To be a philosopher is not merely to have subtle thoughts, nor even to found a school, but so to love wisdom as to live according to its dictates, a life of simplicity, independence, magnanimity and trust.

Whatever beauty we behold, the more it is distant, serene, and cold, the purer and more durable it is. It is better to warm ourselves with ice than with fire.

We communicate like the burrows of foxes, in silence and darkness, under ground. We are undermined by faith and love.

Live the life you've dreamed.

I have great faith in a seed.

No definition of poetry is adequate unless it be poetry itself. The most accurate analysis by the rarest wisdom is yet insufficient, and the poet will instantly prove it false by setting aside its requisitions. It is indeed all that we do not know.
