Lévi mentions the Preliminary Discourse in his correspondence with his student Baron Spédalieri, saying:
- "...the economy of numbers necessitates the alliance of science and of faith which will constitute the absolute reason for the human verb upon an unshakable foundation, analogous to that of God, as I have demonstrated in the preliminary discourse of my second edition to Dogma and Ritual..."
In the present text, Levi says:
- "To be [a] poet, it is to create; it is not to dream nor to lie.
God was [a] poet when He made the world, and His immortal epic is written with stars.
The Sciences have received from Him the secrets of poetry, because the keys of harmony were delivered into their hands.
Numbers are poets, because they sing with notes [that are] always right, which gives rapture to the genius of Pythagoras."
The Editor's Appendix contains 3 sections:
- Three letters from Lévi to Baron Spédalieri which mention the Preliminary Discourse
- Two chapters from Book 2 of The Key to the Great Mysteries which are related to the Verb
- The Introduction to Ritual of High Magic which also has some relevant information about the Verb
