Whoever thinks algebra is a trick in obtaining unknowns has thought it in vain. No attention should be paid to the fact that algebra and geometry are different in appearance. Algebras (jabbre and maqabeleh) are geometric facts which are proved by propositions five and six of Book two of Elements.

There are people who strictly deprive themselves of each and every eatable, drinkable, and smokable which has in any way acquired a shady reputation. They pay this price for health. And health is all they get for it. How strange it is. It is like paying out your whole fortune for a cow that has gone dry.
Mark Twain
Often the magical elements in my books are standing in for elements of the real world, the small and magical-in-their-own-right sorts of things that we take for granted and no longer pay attention to, like the bonds of friendship that entwine our own lives with those of other people and places.
Charles de Lint
