The 13th of June is Yeats Day, the anniversary of Yeats’ birth. Best known as a poet, Yeats had philosophic interests. He admired idealism, and was well known for reading neoPlatonists such as Plotinus. In his essay Bishop Berkeley, he extols the imagination that underlay philosophy from Spinoza to Hegel.
Yeats was not a pure idealist (a term that to him evoked Kant, rather than Berkeley who was “idealist and realist alike”.) Yeats also rejected “the new naturalism that leaves man helpless before the contents of his own mind”, quoting Nietzsche’s Zarathustra “Am I a barrel of memories to give you my reasons?” (Bishop Berkeley).
As mentioned previously, Yeats and Wilde knew each other and Wilde made a strong impression on Yeats. In The Parting of the Veil (1922) Yeats tells of Wilde’s attempts to copy (wear a mask) opposite to the natural self or the natural world.
By 1918 in Arnica Silentia Lunare Yeats has developed his view and says,
The other self, the anti-self or the antithetical self, as one may choose to name it, comes but to those who are no longer deceived, whose passion is reality.
Scholastic philosophy is considered to begin with John Scotus Erigena who flourished about the year 860, and who must not be confused with the Duns Scotus of a later date. We do not quite know whether he belonged to Ireland or to Scotland, for Scotus points to Scotland, and Erigena to Ireland. With him true philosophy first begins, and his philosophy in the main coincides with the idealism of the Neo-Platonists. […]
Scotus was also the author of some original works, which are not without depth and penetration, upon nature and its various orders (De naturæ divisione), &c. Dr. Hjort, of Copenhagen, published an epitome of the writings of Scotus Erigena, in 1823. Scotus Erigena sets to work philosophically, expressing himself in the manner of the Neo-Platonists, and not freely, and as from himself, Thus in the method of expression adopted by Plato, and also by Aristotle, we are rejoiced to find a new conception, and on bringing it to the test of philosophy, to find it both correct and profound; but here everything is ready to hand, cut and dry. Yet, with Scotus, theology is not yet built on exegesis, and on the authority of the Church; the Church in many cases rejected his writings. Thus Scotus is reproached by a Lyons church council […] Scotus Erigena hence even said: “The true Philosophy is the true Religion, and the true Religion is the true Philosophy. The separation came later on. Scotus then made a beginning, but properly he does not belong to the scholastics
