I love snow, snow, and all the forms of radiant frost.

The most common form of terrorism in the U.S.A. is that carried on by bulldozers and chainsaws. It is not enough to understand the natural world; the point is to defend and preserve it. Sentiment without action is the ruin of the soul.

Nature can't evolve a species that hasn't the will to survive. Individuals might be bred to sacrifice themselves, but the race as a whole can never cease to exist.

Every spring I hear the thrush singing in the glowing woods he is only passing through. His voice is deep, then he lifts it until it seems to fall from the sky. I am thrilled. I am grateful. Then, by the end of morning, he's gone, nothing but silence out of the tree where he rested for a night. And this I find acceptable. Not enough is a poor life. But too much is, well, too much. Imagine Verdi or Mahler every day, all day. It would exhaust anyone.

The fact that the colors in the flower have evolved in order to attract insects to pollinate it is interesting; that means insects can see the colors. That adds a question: does this aesthetic sense we have also exist in lower forms of life?

It is the sweetest spring within the memory of man. So green, so mild, so beautiful! Ah, what a contrast between nature without and my own soul so torn with doubt and terror!
