" An illusion has three stages.

"First there is the setup, in which the nature of what might be attempted at is hinted at, or suggested, or explained. The apparatus is seen. volunteers from the audience sometimes participate in preparation. As the trick is being setup, the magician will make use of every possible use of misdirection.

"The performance is where the magician's lifetime of practice, and his innate skill as a performer, cojoin to produce the magical display.

"The third stage is sometimes called the effect, or the prestige, and this is the product of magic. If a rabbit is pulled from a hat, the rabbit, which apparently did not exist before the trick was performed, can be said to be the prestige of that trick. "
