In 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.
Henry David ThoreauThe lichen on the rocks is a rude and simple shield which beginning and imperfect Nature suspended there. Still hangs her wrinkledtrophy.
Henry David ThoreauYou must live in the present, launch yourself on every wave, find your eternity in each moment.
Henry David ThoreauIt will be seen that we contemplate a time when man's will shall be law to the physical world, and he shall no longer be deterredby such abstractions as time and space, height and depth, weight and hardness, but shall indeed be the lord of creation.
