The Faculties dominate the waking life of the human being and they dominate A Vision. They were the first major part of the system that Yeats mastered, and he wrote “The Phases of the Moon” and the delineations of the phases’ characteristics that became “The Twenty-Eight Embodiments” of A Vision in “my first excitement when it seemed that I understood human nature for the first time… .” For readers too, they are one of the more accessible aspects of the system, although the geometry and “rules for finding” that Yeats uses to expound their development and variations can appear arbitrary, too complex for ready understanding and too simplistic to describe the human psyche.

As explained in the previous chapter, the Faculties, existing within the psyche and experience, are reflections of aspects of the spiritual human being, the Principles, products of their incarnation. The Faculties are acquired, in the sense that they are not part of the individual essence and are specific to a single incarnation, though their characteristics follow inevitably from previous lives.

They are roughly similar to the traditional “trilogy of mind”—the cognitive, affective, and conative faculties— plus immediate environment. The fact that they are four rather than three is fundamental to the dynamics of Yeats's system, part of its intrinsic duality and emphasis on antithesis.
