What we call wisdom is the result of all the wisdom of past ages. Our best institutions are like young trees growing upon the roots of the old trunks that have crumbled away.
There is no right more universal and more sacred, because lying so near the root of existence, than the right of men to their own labor.
A man is a fool who sits looking backward from himself in the past. Ah, what shallow, vain conceit there is in man! Forget the things that are behind. That is not where you live. Your roots are not there. They are in the present; and you should reach up into the other life.
All human affairs follow nature's great analogue, the growth of vegetation. There are three periods of growth in every plant. The first, and slowest, is the invisible growth by the root; the second and much accelerated is the visible growth by the stem; but when root and stem have gathered their forces, there comes the third period, in which the plant quickly flashes into blossom and rushes into fruit.
To the great tree-loving fraternity we belong. We love trees with universal and unfeigned love, and all things that do grow under them or around them - the whole leaf and root tribe.
