Yeats's Eugenical and Psychical Aesthetics

It should never be forgotten that Yeats is perfectly capable of contradicting himself even about some of his most cherished speculations. Nevertheless, the theoretical aspect of his later work exhibits a marked internal coherence: it is not possible to separate his ideas about society, his theories about the spirit world, his doctrine of the image, his cyclical theory of history. It is for this reason that I have referred, in brief, to “Eugenical and Psychical Aesthetics.”
