The poem
Shall we conceal the Case, or tell it - We who believe the evidence? Here and there the watch-towers knell it With a sullen significance, Heard of the few who hearken intently and carry an eagerly upstrained sense.
Hearts that are happiest hold not by it; Better we let, then, the old view reign; Since there is peace in it, why decry it? Since there is comfort, why disdain? Note not the pigment the while that the painting determines humanity's joy and pain!
