In the New Poems W. B. Yeats attempt to absorb the antinomy of tragedy and joy in Oneness. The objective coincides with increasingly right-wing sympathy evident in Yeats during the 1930s. Yeats first used the phrase "tragic joy" in a 1904 Samhain, the Irish theatrical periodical. The period of Yeats' first use of the phrase follows his intense reading of Nietzsche in 1902 and 1903. The theme of tragic joy is certainly at the heart of Nietzsche's early work, The Birth of Tragedy. For Yeats, as for Nietzsche, it is a cycle that is centred in "the very heart of Nature", a rebirth from the navel of the goddess. For Yeats, the movement of the gyres means that Hector "is dead". In November 1936 Yeats had written "An Acre of Grass". The poem advocates truth and inspiration as arising from Nature and the body, rather than from the mind.
