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.
