The Tower (1928), Sailing to Byzantium http://poetry.poetryx.com/poems/1575/
Context: Once out of nature I shall never take
My bodily form from any natural thing,
But such a form as Grecian goldsmiths make
Of hammered gold and gold enamelling
To keep a drowsy Emperor awake;
Or set upon a golden bough to sing
To lords and ladies of Byzantium
Of what is past, or passing, or to come.

“THE best way to suppose what may come, is to remember what is past.”

“And what 's impossible can't be,
And never, never comes to pass.”
The Maid of the Moor, reported in Bartlett's Familiar Quotations, 10th ed. (1919).
1880s, The Future of the Colored Race (1886)
Context: Of course this result will not be reached by any hurried or forced processes. It will not arise out of any theory of the wisdom of such blending of the two races. If it comes at all, it will come without shock or noise or violence of any kind, and only in the fullness of time, and it will be so adjusted to surrounding conditions as hardly to be observed. I would not be understood as advocating intermarriage between the two races. I am not a propagandist, but a prophet. I do not say that what I say should come to pass, but what I think is likely to come to pass, and what is inevitable. While I would not be understood as advocating the desirability of such a result, I would not be understood as deprecating it.
