There are no fixtures in nature. The universe is fluid and volatile. Permanence is but a word of degrees. Our globe seen by God is a transparent law, not a mass of facts. The law dissolves the fact and holds it fluid. Our culture is the predominance of an idea which draws after it this train of cities and institutions. Let us rise into another idea: they will disappear. The Greek sculpture is all melted away, as if it had been statues of ice; here and there a solitary figure or fragment remaining, as we see flecks and scraps of snow left in cold dells and mountain clefts, in June and July. For the genius that created it creates now somewhat else. The Greek letters last a little longer, but are already passing under the same sentence, and tumbling into the inevitable pit which the creation of new thought opens for all that is old. The new continents are built out of the ruins of an old planet; the new races fed out of the decomposition of the foregoing. New arts destroy the old. See the investment of capital in aqueducts made useless by hydraulics; fortifications, by gunpowder; roads and canals, by railways; sails, by steam; steam by electricity. 

You admire this tower of granite, weathering the hurts of so many ages. Yet a little waving hand built this huge wall, and that which builds is better than that which is built. The hand that built can topple it down much faster. Better than the hand, and nimbler, was the invisible thought which wrought through it; and thus ever, behind the coarse effect, is a fine cause, which, being narrowly seen, is itself the effect of a finer cause. Every thing looks permanent until its secret is known. A rich estate appears to women a firm and lasting fact; to a merchant, one easily created out of any materials, and easily lost. An orchard, good tillage, good grounds, seem a fixture, like a gold mine, or a river, to a citizen; but to a large farmer, not much more fixed than the state of the crop. Nature looks provokingly stable and secular, but it has a cause like all the rest; and when once I comprehend that, will these fields stretch so immovably wide, these leaves hang so individually considerable? Permanence is a word of degrees. Every thing is medial. Moons are no more bounds to spiritual power than bat-balls. 

The key to every man is his thought. Sturdy and defying though he look, he has a helm which he obeys, which is the idea after which all his facts are classified. He can only be reformed by showing him a new idea which commands his own. The life of man is a self-evolving circle, which, from a ring imperceptibly small, rushes on all sides outwards to new and larger circles, and that without end. The extent to which this generation of circles, wheel without wheel, will go, depends on the force or truth of the individual soul. For it is the inert effort of each thought, having formed itself into a circular wave of circumstance, ó as, for instance, an empire, rules of an art, a local usage, a religious rite, ó to heap itself on that ridge, and to solidify and hem in the life. But if the soul is quick and strong, it bursts over that boundary on all sides, and expands another orbit on the great deep, which also runs up into a high wave, with attempt again to stop and to bind. But the heart refuses to be imprisoned; in its first and narrowest pulses, it already tends outward with a vast force, and to immense and innumerable expansions.

Adapted from Frankenstein by Mary Shelley (1818)

No human being could have passed a happier childhood than myself. My parents were possessed by the very spirit of kindness and indulgence. We felt that they were not the tyrants to rule our lot according to their caprice, but the agents and creators of all the many delights which we enjoyed. When I mingled with other families I distinctly discerned how peculiarly fortunate my lot was, and gratitude assisted the development of filial love.

My temper was sometimes violent, and my passions vehement; but by some law in my temperature they were turned not towards childish pursuits but to an eager desire to learn, and not to learn all things indiscriminately. I confess that neither the structure of languages, nor the code of governments, nor the politics of various states possessed attractions for me. It was the secrets of heaven and earth that I desired to learn; and whether it was the outward substance of things or the inner spirit of nature and the mysterious soul of man that occupied me, still my inquiries were directed to the metaphysical, or in it highest sense, the physical secrets of the world. . .

. . .I feel exquisite pleasure in dwelling on the recollections of childhood, before misfortune had tainted my mind and changed its bright visions of extensive usefulness into gloomy and narrow reflections upon self. Besides, in drawing the picture of my early days, I also record those events which led, by insensible steps, to my after tale of misery, for when I would account to myself for the birth of that passion which afterwards ruled my destiny, I find it arise, like a mountain river, from ignoble and almost forgotten sources; but, swelling as it proceeded, it became the torrent which, in its course, has swept away all my hopes and joys.
