This yeats Centennial Year will witness the publication of widespread comment and encomium, “as though,” in Yeats's own words, “it were firmly established that the dead delight in anniversaries.” Now, as his first century joins its circle, Yeats is securely one of the “passionate dead,” who are, in his version of Ben Jonson's line, “So rammed with life they can but grow in life with being.” “Under Ben Bulben,” the elegiac poem which ends with Yeats's epitaph, written only a few months before he died in 1939, says of grave diggers
They but thrust their buried men
Back in the human mind again.
When the grave diggers had thrust Yeats back in the human mind, T. S. Eliot in a memorial lecture in 1940 called him “the greatest poet of our time—certainly the greatest in this language, and so far as I am able to judge, in any language.” Few have contradicted this evaluation. The mass of biography, criticism, exegesis in the years since Yeats died has grown so enormously that his poetry has at times seemed to face the fate he thought the human imagination had suffered in the nineteenth century, that of being “laid in a great tomb of criticism.” In his Centennial Year scholars might most profitably concern themselves not with the mounting tomb of criticism but rather with the texts of Yeats's works and the tools for study which the quarter century since his death has produced.
