There is reason in the distinction of civil and uncivil. The manners are sometimes so rough a rind that we doubt whether they cover any core or sap-wood at all.
Henry David ThoreauMeasure your health by your sympathy with morning and spring. If there is no response in you to the awakening of nature -if the prospect of an early morning walk does not banish sleep, if the warble of the first bluebird does not thrill you -know that the morning and spring of your life are past. Thus may you feel your pulse.
Henry David Thoreauf the injustice is part of the necessary friction of the machine of government, let it go, let it go; perchance it will wear smooth - certainly the machine will wear out... but if it is of such a nature that it requires you to be the agent of injustice to another, then I say, break the law. Let your life be a counter-friction to stop the machine. What I have to do is to see, at any rate, that I do not lend myself to the wrong which I condemn.
Henry David ThoreauIn all her products, Nature only develops her simplest germs. One would say that it was no great stretch of invention to create birds. The hawk which now takes his flight over the top of the wood was at first, perchance, only a leaf which fluttered in its aisles. From rustling leaves she came in the course of ages to the loftier flight and clear carol of the bird.
