Note 12 — Extract from an unpublished Poem on Freedom.

Though Socrates and Plato, particularly the former, are generally admitted by writers of authority, among whom, indeed, are Polycarpe, Chrysotom, and Eusebius, to have in a manner suspected rather than believed, the immortality of the soul; yet we have no evidence of their ever having, by the finest process of ratiocination, so thoroughly convinced themselves as to introduce it generally as a tenable thesis on the portico. A beautiful thread of implicit belief and fervent hope, of after life, assimilating to the hunting-ground of our own American Indians, and though sensuous still, a step far in advance of the black void of ancient philosophy, has always run through the higher mythologies of the Negro. So notorious, indeed, was the fact among early Christians, that that ubiquitous riddle, "Prestor John," was, by believers, regarded as having a locale in Central Africa; while Henry of Portugal actually despatched two ambassadors, Corvilla and Payvan, to a rumored Christian court, south of the Sahara.—Edin.
