We say justly that the weak person is flat, for, like all flat substances, he does not stand in the direction of his strength, that is, on his edge, but affords a convenient surface to put upon. He slides all the way through life.... But the brave man is a perfect sphere, which cannot fall on its flat side and is equally strong every way.

Henry David ThoreauWhen we consider the weak and nerveless periods of some literary men, who perchance in feet and inches come up to the standard oftheir race, and are not deficient in girth also, we are amazed at the immense sacrifice of thews and sinews. What! these proportions, these bones,--and this their work! Hands which could have felled an ox have hewed this fragile matter which would not have tasked a lady's fingers! Can this be a stalwart man's work, who has a marrow in his back and a tendon Achilles in his heel?
