Our Old Friend Dualism

All hail to him, the Protean! A tough old chap is he:
Spinoza and the Monists cannot make him cease to be.
We pound him with our “Truth, Sir, please!” and quite appear to still him:
He laughs; holds Bergson up, and James; and swears we cannot kill him.
We argue them pragmatic cheats. “Aye,” says he. “They’re deceiving:
But I must live; for flamens plead I am all that’s worth believing!”
