Magic exteriorizes mankind's irrepressible desire to transform the world, not through work, but through extraordinary means. By the use of white magic (alchemy), mankind aspires to know the secrets of the world, to find the Philosopher's Stone. By the use of black magic, man makes a pact with the devil to gain power, pleasure or self-affirmation. Myth and fantasy are not opposed concepts, but they are diverse. It falls on the hands of the researcher to distinguish between the varied forms of transcendence (sacred or cosmic in myth, plastic or natural in fantasy) and between the different kinds of timeframe (absolute in myth, relative in fantasy).
