In order to avoid these errors, we must employ a symbolism which excludes them, by not applying the same sign in different symbols and by not applying signs in the same way which signify in different ways. A symbolism, that is to say, which obeys the rules of logical grammar — of logical syntax. (The logical symbolism of Frege and Russell is such a language, which, however, does still not exclude all errors.)

The common error of ordinary religious practice is to mistake the symbol for the reality, to look at the finger pointing the way and then to suck it for comfort rather than follow it.

A religious symbol conveys its message even if it is no longer consciously understood in every part. For a symbol speaks to the whole human being and not only to the intelligence.

person who has had a mystical experience knows that all the symbolic expressions of it are faulty. The symbols don’t render the experience, they suggest it. If you haven’t had the experience, how can you know what it is? Try to explain the joy of skiing to somebody living in the tropics who has never even seen snow. There has to be an experience to catch the message, some clue — otherwise you’re not hearing what is being said. MOYERS:

Perhaps that had been one of the ineradicable faults of mankind - for even a convinced atheist had to admit there were faults - that it was never content with a thing as a thing; it had to turn things into symbols of other things. A rainbow was never only a rainbow; a storm was a sign of celestial anger; and even from the puddingy earth came forth dark chthonian gods. What did it all mean? What an agnostic believed and what the willowy parson believed were not only irreconcilable systems of thought: they were equally valid systems of thought because, somewhere along the evolutionary line, man, developing this habit of thinking of symbols, had provided himself with more alternatives than he could manage. Animals moved in no such channel of imagination - they copulated and they ate; but the the saint, bread was a symbol of life, as the phallus was to the pagan. The animals themselves were pressed into symbolic service - and not only in the medieval bestiaries, by any means.

Such a usage was a distortion, although man seemed unable to ratiocinate without it. That had been the trouble right from the beginning. Perhaps it had even been the beginning, back among the first men that man could never get clearly defined (for the early men, being also symbols, had to be either lumbering brutes, or timid noble savages, or to undergo some other interpretation). Perhaps the first fire, the first tool, the first wheel, the first carving in a limestone cave, had each possessed a symbolic rather than a practical value, had each been pressed to serve distortion rather than reality. It was a sort of madness that had driven man from his humble sites on the edges of woods into towns and cities, into arts and wars, into religious crusades, into martyrdom and prostitution, into dyspepsia and fasting, into love and hatred, into this present cul-de-sac; it had all come about in pursuit of symbols. In the beginning was the symbol, and darness was over the face of the Earth.

Instead of the word 'love' there was an enormous heart, a symbol sometimes used by people who have trouble figuring out the difference between words and shapes.

(…) symbolism did not fall out of heaven or rise out of subterranean depths: it was elaborated like language, by the human reality…

"All the comics are sigils. "Sigil" as a word is out of date. All this magic stuff needs new terminology because it's not what people are being told it is at all. It's not all this wearying symbolic misdirection that's being dragged up from the Victorian Age, when no-one was allowed to talk plainly and everything was in coy poetic code. The world's at a crisis point and it's time to stop bullshitting around with Qabalah and Thelema and Chaos and Information and all the rest of the metaphoric smoke and mirrors designed to make the rubes think magicians are 'special' people with special powers. It's not like that. Everyone does magic all the time in different ways. "Life" plus "significance" = magic."

The problem of the theologian is to keep his symbol translucent, so that it may not block out the very light it is supposed to convey.

Sometimes a symbol holds more power than the thing it represents. Like the symbol for Thing, the one I created that is confusing and abstract and makes people ask, What is that thing? And I always reply, “If you already knew, why did you ask?

"We shouldn’t have tried to create new symbols,” he said. We should’ve realized we weren’t supposed to introduce uncertainties into accepted belief, that we weren’t supposed to stir up curiosity about God. We are daily confronted by the terrifying instability of all things human, yet we permit our religions to grow more rigid and controlled, more conforming and oppressive. What is this shadow across the highway of Divine Command? It is a warning that institutions endure, that symbols endure when their meaning is lost, that there is no summa of all attainable knowledge.

Tautology and contradiction are, however, not senseless; they are part of the symbolism, in the same way that “0” is part of the symbolism of Arithmetic.

A true symbol appears only when there is a need to express what thought cannot think or what is only divined or felt.

But this metaphysics, like this science, has enfolded its deeper life in a rich tissue of symbols, forgetting something that, while science needs symbols for its analytical development, the main object of metaphysics is to do away with symbols.
