“Still let us not be over-sanguine of a speedy final triumph. Let us be quite sober. Let us diligently apply the means, never doubting that a just God, in his own good time, will give us the rightful result.”

“Man was Cadaver’s masker, the harnessing mantle,
Windily master of man was the rotten fathom,
My ghost in his metal neptune
Forged in man’s mineral.
This was the god of beginning in the intricate seawhirl,
And my images roared and rose on heaven’s hill.”
—Dylan Thomas (1914–1953)
