I go to nature to be soothed and healed, and to have my senses put in order.

Now is the time of the illuminated woods ... when every leaf glows like a tiny lamp.

To learn something new, take the path that you took yesterday.

Every walk to the woods is a religious rite, every bath in the stream is a saving ordinance. Communion service is at all hours, and the bread and wine are from the heart and marrow of Mother Earth. There are no heretics in Nature's church; all are believers, all are communicants. The beauty of natural religion is that you have it all the time; you do not have to seek it afar off in myths and legends, in catacombs, in garbled texts, in miracles of dead saints or wine-bibbing friars. It is of today; it is now and here; it is everywhere.

I go to books and to nature as a bee goes to the flower, for a nectar that I can make into my own honey.

It doesn't seem to be that huge a commitment that would create, you know, some kind of really powerful constituency. But the history has been for the United States and Russia especially that nuclear weapons have kind of become part of the identity of the countries.

[Nuclear weapons] now I think I mentioned around 27,000 and during the Cold War the total global arsenal was on the order of 70,000.
