We have learnt that the exploration of the external world by the methods of physical science leads not to a concrete reality but to a shadow world of symbols, beneath which those methods are unadapted for penetrating. Feeling that there must be more behind, we return to our starting point in human consciousness - the one centre where more might become known. There we find other stirrings, other revelations than those conditioned by the world of symbols... Physics most strongly insists that its methods do not penetrate behind the symbolism. Surely then that mental and spiritual nature of ourselves, known in our minds by an intimate contact transcending the methods of physics, supplies just that... which science is admittedly unable to give.

There are deeper types of symbolism, in a sense artificial, and yet such that we could not get on without them. Language, written or spoken, is such a symbolism.

All religious expression is symbolism; since we can describe only what we see, and the true objects of religion are The Seen . The earliest instruments of education were symbols; and they and all other religious forms differed and still differ according to external circumstances and imagery, and according to differences of knowledge and mental cultivation. All language is symbolic, so far as it is applied to mental and spiritual phenomena and action. All words have, primarily, a material sense, howsoever they may afterward get, for the ignorant, a spiritual non-sense. To "retract," for example, is to draw back, and when applied to a statement, is symbolic, as much so as a picture of an arm drawn back, to express the same thing, would he. The very word " spirit" means " breath," from the Latin verb spiro, breathe.

Science aims at constructing a world which shall be symbolic of the world of commonplace experience. It is not at all necessary that every individual symbol that is used should represent something in common experience or even something explicable in terms of common experience. The man in the street is always making this demand for concrete explanation of the things referred to in science; but of necessity he must be disappointed. It is like our experience in learning to read. That which is written in a book is symbolic of a story in real life. The whole intention of the book is that ultimately a reader will identify some symbol, say BREAD, with one of the conceptions of familiar life. But it is mischievous to attempt such identifications prematurely, before the letters are strung into words and the words into sentences. The symbol A is not the counterpart of anything in familiar life.

A symbolism is abstract inasmuch as it signifies a principial reality; it is concrete inasmuch as it communicates the nature of this reality, that is, inasmuch as it renders it present to our experience.

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

There is no need in these mathematical days to defend the use of symbolism. It is regarded by many schools of modern thought as the only safe form of language. Wittgenstein treats symbols as something more than conventional signs, and regards them as corresponding in some way to the reality to which they refer. He would probably accept Gurdjieff’s dictum that: Symbols not only transmit knowledge but show the way to it. Even though other thinkers deny any objective reference to symbols, no one questions that symbolism has a power beyond that of ordinary language. It is different with the language of myth. This is despised by superficial thinkers, but the greatest philosophers have known its value.

Symbolic thinking is not the exclusive privilege of the child, of the poet or of the unbalanced mind: it is consubstantial with human existence, it comes before language and discursive reason. The symbol reveals certain aspects of reality – the deepest aspects – which defy any other means of knowledge. Images, symbols and myths are not irresponsible creations of the psyche; they respond to a need and fulfil a function, that of bringing to light the hidden modalities of being.

We often dismiss controversies or concerns by waving our hands and saying something like, “Oh, that’s merely symbolic,” as if the meaning we give to symbols is somehow irrelevant compared with more tangible things. But symbolism — the way we reduce broad concerns, agendas, and visions to images or rituals — has played a defining role in human life since there have been humans. Try burning a flag or a cross in front of the wrong audience and then tell me symbolism is nothing.

And because this Experimental Science is wholly ignored by the general run of students, for that reason I can not convince people of its utility unless I show at the same time its excellence and its property. This science alone, then, knows how to test perfectly by experience what can be done by nature, what by the industry of art, what by imposture; what the incantations, conjurations, invocations, deprecations, sacrifices (which are magical devices) seek and dream of; and what is done in them, so that all falsity may be removed and that only the truth of art and nature be retained. This science alone teaches one to consider all the insanities of magicians, not that they may be confirmed but that they may be avoided, just as logic considers sophistical argument.

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.

The research into symbols is essential to interpret the supernatural world, not only the one outside us but also the one inside us through the sanctifying grace and the gifts of the Holy Spirit. Keeping in mind the love of Africans for rituals, it is important that their meaning interiorises the values involved.

We can now return to the distinction between language and symbolism. A symbol is language and yet not language. A mathematical or logical or any other kind of symbol is invented to serve a purpose purely scientific; it is supposed to have no emotional expressiveness whatever. But when once a particular symbolism has been taken into use and mastered, it reacquires the emotional expressiveness of language proper. Every mathematician knows this. At the same time, the emotions which mathematicians find expressed in their symbols are not emotions in general, they are the peculiar emotions belonging to mathematical thinking.
