forms flee as the driven
snows, itself secret, its works driven before it in flocks and
multitudes, (as the ancient represented nature by Proteus,[500] a
shepherd), and in undescribable variety. It publishes itself in
creatures, reaching from particles and spicula, through transformation
on transformation to the highest symmetries, arriving at consummate
results without a shock or a leap. A little heat, that is, a little
motion, is all that differences the bald, dazzling white, and deadly
cold poles of the earth from the prolific tropical climates. All changes
pass without violence, by reason of the two cardinal conditions of
boundless space and boundless time. Geology has initiated us into the
secularity of nature, and taught us to disuse our dame-school measures,
and exchange our Mosaic[501] and Ptolemaic schemes[502] for her large
style. We know nothing rightly, for want of perspective. Now we learn
what patient periods must round themselves before the rock is formed,
then before the rock is broken, and the first lichen race has
disintegrated the thinnest external plate into soil, and opened the door
for the remote Flora,[503] Fauna,[504] Ceres,[505] and Pomona,[506] to
come in. How far off yet is the trilobite! how far the quadruped! how
inconceivably remote is man! All duly arrive,[507] and then race after
race of men. It is a long way from granite to the oyster; farther yet to
Plato,[508] and the preaching of the immortality of the soul. Yet all
must come, as surely as the first atom has two sides.

7. Motion or change, and identity or rest, are the first and second
secrets of nature: Motion and Rest. The whole code of her laws may be
written on the thumb-nail, or the signet of a ring. The whirling
bubble on the surface of a brook, admits us to the secret of the
mechanics of the sky. Every shell on the beach is a key to it. A
little water made to rotate in a cup explains the formation of the
simpler shells; the addition of matter from year to year, arrives at
last at the most complex forms; and yet so poor is nature with all her
craft, that, from the beginning to the end of the universe, she has
but one stuff,--but one stuff with its two ends, to serve up all her
dream-like variety. Compound it how she will, star, sand, fire, water,
tree, man, it is still one stuff, and betrays the same properties.

8. Nature is always consistent, though she feigns to contravene her
own laws. She keeps her laws, and seems to tran
