We have need to be earth-born as well as heaven-born, gegeneis, as was said of the Titans of old, or in a better sense than they.
Henry David ThoreauDuty is one and invariable; it requires no impossibilities, nor can it ever be disregarded with impunity.
Henry David ThoreauMen should not labor foolishly like brutes, but the brain and the body should always, or as much as possible, work and rest together, and then the work will be of such a kind that when the body is hungry the brain will be hungry also, and the same food will suffice for both; otherwise the food which repairs the waste energy of the overwrought body will oppress the sedentary brain, and the degenerate scholar will come to esteem all food vulgar, and all getting a living drudgery.
