The Tree of Life

"The affinities of all the beings of the same class have sometimes been represented by a great tree... As buds give rise by growth to fresh buds, and these if vigorous, branch out and overtop on all sides many a feebler branch, so by generation I believe it has been with the great Tree of Life, which fills with its dead and broken branches the crust of the earth, and covers the surface with its ever branching and beautiful ramifications."
C. Darwin

Il destino del filosofo

Again: as the profound calm which only apparently precedes and prophesies of the storm, is perhaps more awful than the storm itself; for, indeed, the calm is but the wrapper and envelope of the storm; and contains it in itself, as the seemingly harmless rifle holds the fatal powder, and the ball, and the explosion; so the graceful repose of the line, as it silently serpentines about the oarsmen before being brought into actual play—this is a thing which carries more of true terror than any other aspect of this dangerous affair. But why say more? All men live enveloped in whale-lines. All are born with halters round their necks; but it is only when caught in the swift, sudden turn of death, that mortals realize the silent, subtle, ever-present perils of life. And if you be a philosopher, though seated in the whale-boat, you would not at heart feel one whit more of terror, than though seated before your evening fire with a poker, and not a harpoon, by your side.
