I am in love with this world . . . I have climbed its mountains, roamed its forests, sailed its waters, crossed its deserts, felt the sting of its frosts, the oppression of its heats, the drench of its rains, the fury of its winds, and always have beauty and joy waited upon my goings and comings.

The simplicity of winter has a deep moral. The return of Nature, after such a career of splendor and prodigality, to habits so simple and austere, is not lost either upon the head or the heart. It is the philosopher coming back from the banquet and the wine to a cup of water and a crust of bread.

All sounds are sharper in winter; the air transmits better. At night I hear more distinctly the steady roar of the North Mountain. In summer it is a sort of complacent purr, as the breezes stroke down its sides; but in winter always the same low, sullen growl.

The Universe is a pretty big place... And the one thing I know about nature is it hates to waste anything. So I guess I'd say if it is just us, an awful lot of space is going to waste. The earth is not alone, it is not like a single apple on a tree; there are many apples on the tree, and there are many trees in the orchard.

Basically [United States and France] said "We will use nuclear weapons whenever it suits our purposes to do so." So this expansion of doctrines regarding possible use of nuclear weapons makes them more, you know, sort of, salient and important and so it's increasing the perceived political value of nuclear weapons and therefore causing or contributing to possible proliferation.

The atmosphere of our time is fast being cleared of the fumes and deadly gases that arose during the carboniferous age of theology.

I think rain is as necessary to the mind as to vegetation. My very thoughts become thirsty, and crave the moisture.
