I have just been through the process of killing a cistudo for the sake of science; but I cannot excuse myself for this murder, and see that such actions are inconsistent with the poetic perception, however they may serve science, and will affect the quality of my observations. I pray that I may walk more innocently and serenely through nature. No reasoning whatever reconciles me to this act. It affects my day injuriously. I have lost some self-respect. I have a murderer's experience to a degree.
Henry David ThoreauThe mission of men there seems to be, like so many busy demons, to drive the forest all out of the country, from every solitary beaver swamp and mountain-side, as soon as possible.
Henry David ThoreauIt would be worth the while to select our reading, for books are the society we keep; to read only the serenely true; never statistics, nor fiction, nor news, nor reports, nor periodicals, but only great poems, and when they failed, read them again, or perchance write more. Instead of other sacrifice, we might offer up our perfect (teleia) thoughts to the gods daily, in hymns or psalms. For we should be at the helm at least once a day.
Henry David ThoreauAll men are partially buried in the grave of custom, and of some we see only the crown of the head above ground. Better are the physically dead, for they more lively rot. Even virtue is no longer such if it be stagnant. A man's life should be constantly as fresh as this river. It should be the same channel, but a new water every instant.
Henry David ThoreauMost people dread finding out when they come to die that they have never really lived.
