Rhetoric as Epistemic

This World is not Conclusion.
A Species stands beyond—
Invisible, as Music—
But positive, as Sound—
It beckons, and it baffles—
Philosophy—don't know—
And through a Riddle, at the last—
Sagacity, must go—
To guess it, puzzles scholars—
To gain it, Men have borne
Contempt of Generations
And Crucifixion, shown—
Faith slips—and laughs, and rallies—
Blushes, if any see—
Plucks at a twig of Evidence—
And asks a Vane, the way—
Much Gesture, from the Pulpit—
Strong Hallelujahs roll—
Narcotics cannot still the Tooth
That nibbles at the soul—
—Emily Dickinson, (c. 1862)
