I love forms beyond my own, and regret the borders between us

The creature called man has a strange history. He is not of one piece, nor was he born of a single moment in time. His elementary substance is stardust almost as old as the universe.

Life, unlike the inanimate, will take the long way round to circumvent barrenness. A kind of desperate will resides even in a root.

Like the herd animals we are, we sniff warily at the strange one among us.

When man becomes greater than nature, nature, which gave him birth, will respond.

We think we learn from teachers, and we sometimes do. But the teachers are not always to be found in school or in great laboratories. Sometimes what we learn depends upon our own powers of insight.
