Philolaus, the Pythagorean, invented it.
Aristotle (mis?)interpreted it.
An antiplanet (made of antimatter?) balancing the universe against the heavy Earth?
The shield protecting us from the central fire around which, Philolaus said, all planets revolve.

What this means to you
In some weird, obscure way, antichton is good for you, one might even say essential. It helps you (that part of you which is also me) be, and that, after all, is almost half the story, right?
So, you tell yourself (no, I tell you to tell yourself, but then, that's how it works in these parts, I play my role and a little bit of yours) perhaps antichton deserves a website. But wait a second, and prepare to be frightened or if not, at least ever so mildly amused: isn't the web some sort of balancing space? Don't some of us use it to level the playing field? Don't others use it to balance their reality with a healthy dose of virtuality?

Frighten you yet?
Oh, well, it was worth a try; still, I hope you understood that far from being some obscure and remote ... thing, antichton might actually be grinning at you right now, from the screen of your computer. Perhaps you've been wandering the hills and valleys of antichton for a while now, unknowingly; or even, dare I say it, you may have become an antichtonian, you may have ceased being an earthling right about the middle of the 90s, when that modem started screeching behind your desk and the calm, genial voice told you: Welcome! You've got mailed.
All right, you may go now. Remember, though, just like the above, some things may not make sense. Don't be too hard on them.
