To the man who cherishes a secret in his breast, there is a still greater secret unexplored. Our most indifferent acts may be a matter for secrecy, but whatever we do with the utmost truthfulness and integrity, by virtue of its pureness, must be transparent as light.
Henry David ThoreauSee how he cowers and sneaks, how vaguely all the day he fears, not being immortal nor divine, but the slave and prisoner of his own opinion of himself, a fame won by his own deeds. Public opinion is a weak tyrant compared with our own private opinion. What a man thinks of himself, that it is which determines, or rather indicates, his fate.
Henry David ThoreauFirst, there is the power of the Wind, constantly exerted over the globe... Here is an almost incalculable power at our disposal, yet how trifling the use we make of it.
Henry David ThoreauOnce I went so far as to slaughter a woodchuck which ravaged my bean-field,--effect his transmigration, as a Tartar would say,--and devour him, partly for experiment's sake; but though it afforded me a momentary enjoyment, notwithstanding a musky flavor, I saw that the longest use would not make that a good practice, however it might seem to have your woodchucks ready dressed by the village butcher.
