"At the beginning of his literary life Thomas Vaughan was influenced deeply by the works of Cornelius Agrippa and especially by THE THREE BOOKS OF OCCULT PHILOSOPHY. He drew much from this source, as any annotations are designed to shew; but the matter of Agrippa suffers a certain transmutation in the alembic of his own mind... Cornelius Agrippa mentions, on the authority of Cicero, a "sovereign grade of contemplative perfection" wherein the soul knows all things in the light of ideas. De Occulta Philosophia, Lib. iii, c. 50. He speaks also in the language of Plato and the successors of "ascending to the intellectual life" and so attaining "the first unity." Ibid. t iii, 55."
