Note that because that was an actual question is the question mark in use. To answer mine own query; Dove or Swan refers to a later chapter of A Vision[B] by William Butler Yeats. The playwright laureate, politician, and archpoet of the Irish Free State has (as of late) become of interest to me. All right, maybe more of fixation or obsession. I however aim use for the material of that section–indeed the whole book–for examination of the spiritual in our time. Religion and contemplation of the divine are almost the leading discussions to-day and I think I have something constructive to add. So browse away and enjoy.
