This final section of "The Three Books of Occult Philosophy" includes new translations of extracts from Agrippa's work "De Incertitudine et Vanitate Scientiarum" (1530) and the potentially apocryphal "Liber Quartus de Occulta Philosophia" (1559), which also contains the Heptameron, or Elementa Magica de Petri de Abano.

Agrippa's unique aspects in this book include his fluid use of terminology, moving between 'God' and 'the gods,' and his emphasis on silent contemplation as the best form of prayer.

Book Two of Agrippa's work, "Celestial Magic", explores the celestial realm and can be divided into two parts.

In "Natural Magic," Agrippa discusses how virtue, or power and energy, is present in everything and flows down from the divine to the physical world. He believed that matter and mind are not separate but part of a single substance.
