Let the beauty of what you love be what you do.
Ever since the dawn of civilization, people have not been content to see events as unconnected and inexplicable. They have craved an understanding of the underlying order in the world. Today we still yearn to know why we are here and where we came from. Humanity's deepest desire for knowledge is justification enough for our continuing quest. And our goal is nothing less than a complete description of the universe we live in.
If poets are the unacknowledged legislators of the world, science fiction writers are its court jesters. We are Wise Fools who can leap, caper, utter prophecies, and scratch ourselves in public. We can play with Big Ideas because the garish motley of our pulp origins make us seem harmless.
To be playful is not to be trivial or frivolous, or to act as if nothing of consequence will happen. On the contrary, when we are playful everything that happens is of consequence, for seriousness is a dread of the unpredictable outcome of open possibility. To be serious is to press for a specified conclusion. To be playful is to allow for unlimited possibility.
In the most general terms, the Enlightenment goes back to Plato's belief that truth and beauty and goodness are connected; that truth and beauty, disseminated widely, will sooner or later lead to goodness. (While we're making at effort at truth and goodness, beauty reminds us what we're hold out for.)
Billions of years ago God was creating universes and life; thousands of years ago he was creating angry floods, sin-saving human sacrifices and audible burning bushes. Today he occasionally appears on a piece of toast. To state that God has become reclusive over the years would be an overwhelming understatement.
This world is one of ancient magic peeking from behind the curtains of the present in order to examine the ruckus it set upon the globe. This was the time of harmony and warfare. This was the era of risk and of adventure; of family feuds; of forced affection, of love unrequited; of wars which took lives, by the necks of both the soul and the body, and wrought the poor thing asunder until it was forced to let go or die trying. This was, and always will be, the era belonging to the legendary Royals who fought for love, for truth, and for vengeance.
