By my intimacy with nature I find myself withdrawn from man. My interest in the sun and the moon, in the morning and the evening, compels me to solitude.—Journal, 26 July 1851
Even as the birds sing tumultuously and glance by with fresh and brilliant plumage, so now is Nature's grandest voice heard, and her sharpest flashes seen.—Journal, 19 May 1856
Every morning was a cheerful invitation to make my life of equal simplicity, and I may say innocence, with Nature herself.—Walden
Fishermen, hunters, woodchoppers, and others, spending their lives in the fields and woods, in a peculiar sense a part of Nature themselves, are often in a more favorable mood for observing her, in the intervals of their pursuits, than philosophers or poets even, who approach her with expectation. — Walden—Walden

For my part, I feel that with regard to Nature I live a sort of border life, on the confines of a world, into which I make occasional and transient forays only, and my patriotism and allegiance to the state into whose territories I seem to retreat are those of a moss-trooper.
