The Afterword of Owen Barfield's Poetic Diction: A Study in Meaning, added by the author after the third edition, consists mostly of a list of works in the same exploration as Poetic Diction, works written at or before the first edition of 1928 and in the time between then and the third edition of 1973. It is quite an excellent list of works for people interested in aesthetic literature (and the aesthetic in general), including writers thereof. (Indeed, Barfield's text is itself equally applicable to both appreciators of aesthetic literature and writers thereof.) Being familiar with a majority of the works (or authors) on the list, and what with it being in Poetic Diction, quite the worthwhile book on its own measure, I have no qualms with passing it on here in this post (and adding it, after, to the library). For a better basis of recommendation than my own familiarity, I will say that this is a list of the usual suspects of the field, works and authors that I have frequently seen referenced to this very end. (In truth, this list has reorganized my theoretic reading list.)
The authors and books below all approach the same general subject — the aesthetic modality of being — though often from different approaches, both in content and in the nuances and details of their theoretic/critical systems. The aesthetic, by the very nature of its modality of thought, cannot be spoken of in the manner of the theoretic, arriving at any sense of theoretic definitiveness: it can only be spoken about. To approach it genuinely is invariably to approach along one's own path. As Jung wrote about the exploration of psychology, which is concomitant to the exploration of the aesthetic, "[t]he psychologist should constantly bear in mind that his hypothesis is no more at first than the expression of his own subjective premise and can therefore never lay immediate claim to general validity" (The Spirit in Man, Art, and Literature, Collected Works, 85).
