“Yet he would be wrong in an infinite number of ways.”
Appendix VI : A few principal rituals – Liber Reguli.
Magick Book IV : Liber ABA, Part III : Magick in Theory and Practice (1929)
Context: We know one thing only. Absolute existence, absolute motion, absolute direction, absolute simultaneity, absolute truth, all such ideas: they have not, and never can have, any real meaning. If a man in delirium tremens fell into the Hudson River, he might remember the proverb and clutch at an imaginary straw. Words such as "truth" are like that straw. Confusion of thought is concealed, and its impotence denied, by the invention. This paragraph opened with "We know": yet, questioned, "we" make haste to deny the possibility of possessing, or even of defining, knowledge. What could be more certain to a parabola-philosopher that he could be approached in two ways, and two only? It would be indeed little less that the whole body of his knowledge, implied in the theory of his definition of himself, and confirmed by every single experience. He could receive impressions only be meeting A, or being caught up by B. Yet he would be wrong in an infinite number of ways. There are therefore Aleph-Zero possibilities that at any moment a man may find himself totally transformed. And it may be that our present dazzled bewilderment is due to our recognition of the existence of a new dimension of thought, which seems so "inscrutably infinite" and "absurd" and "immoral," etc. — because we have not studied it long enough to appreciate that its laws are identical with our own, though extended to new conceptions.

“I want to make sure that all versions of GNU remain free.”
1980s, GNU Manifesto (1985)
Context: GNU is not in the public domain. Everyone will be permitted to modify and redistribute GNU, but no distributor will be allowed to restrict its further redistribution. That is to say, proprietary modifications will not be allowed. I want to make sure that all versions of GNU remain free.
