Poetry implies the whole truth. Philosophy expresses a particle of it.

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. Unto a life which I call natural I would gladly follow even a will-o'-the-wisp through bogs and sloughs unimaginable, but no moon nor fire-fly has shown me the cause-way to it. Nature is a personality so vast and universal that we have never seen one of her features.

Going from--toward; it is the history of every one of us.

The kind uncles and aunts of the race are more esteemed than its true spiritual fathers and mothers.

Events, circumstances, etc., have their origin in ourselves. They spring from seeds which we have sown.

It is not a man's duty, as a matter of course, to devote himself to the eradication of any, even the most enormous wrong; he may still properly have other concerns to engage him; but it is his duty, at least, to wash his hands of it, and, if he gives it no thought longer, not to give it practically his support. If I devote myself to other pursuits and contemplations, I must first see, at least, that I do not pursue them sitting upon another man's shoulders.

We need the tonic of wildness...At the same time that we are earnest to explore and learn all things, we require that all things be mysterious and unexplorable, that land and sea be indefinitely wild, unsurveyed and unfathomed by us because unfathomable. We can never have enough of nature.
