Looking through the languages that a friend and I are familiar with (and hungry for exceptions), we found no instance except in English of the practice of using the word for 'determination' or 'strength of purpose' to establish referral to future events.
As in "The Stock Market will collapse."
or "I will try harder next time."
Constructions like "have been" are reasonably common but what is this matter of the Will?
In considering that this peculiarity was English -as in "sourced in Great Britain", at least in partial origin, I struck a nerve and you will all have to forgive me now as I am going to stray farrrr out of the current academic philosophical canon and invoke our weird departed friend Aleister Crowley, a citizen of the United Kingdom of Great Britain in the beginning and especially the middle of the last century.
Because the word "Will" has a strong connotation in the philosophy of this strange fellow, whose magickal system (which was simultaneously a total reworking and faithful torch-bearing of a long old tradition) was nothing more complex than a system of learning to focus the will to effect change. All additional trappings served as atmosphere.
The first and biggest thing when it comes to "Doing Magick" that you learn in this tradition is to create what're called "Sigils" - 'magickal symbols' with a connotation of meaning that you define yourself. They can stand for anything, even and especially concepts that aren't well-expressed in English. In other words... a sigil is a word you make up yourself.
Essentially, in doing sigil magick, you repeat to yourself in a state of serious mystickal focus:
"I will try harder next time." "The Stock Market WILL collapse." "I will find the emerald gate to the thirteenth heaven of et cetera and whatever"
And the experience that keeps these traditions going is the experience of having this work.
The 20th century British Occult traces its root/rotes/routes back a few centuries in the UK, branches through Europe on its way on down through Ancient Greece, Ancient Egypt, eventually even the nation of Israel and India. Little tendrils poking out into the Celtic traditions, solid foundation in the heart of Africa - A startlingly similar map to the one that I might draw if I tried to trace the path of the English that I'm speaking these days.
What is it about a word? Trace a word's geneology and you'll find it's rooted not in your brain, or anyone's brain but in the same place that your geneology terminates. The word you speak now is the end result, still in progress, of billions upon billions of sayings, and a long slow process of finding new ways of wording and new words for saying, new sigils and ways of sigil-making, and why is it called "spelling" the same as a magic "spell"? If a word's not just a flat dead token but one stop on an unbroken chain of growth, linking people across impossible gulfs of time, who's really doing most of the talking? What are we doing when we speak carelessly in matters of importance?
