But I will go further. I will go from ideal fiction to actual, and yet ideal, fact; and say that, as I read history, the most unheroic age which the civilized world ever saw was also the most heroic; that the spirit of man triumphed most utterly over his circumstances, at the very moment when those circumstances were most against him. How and why he did so is a question for philosophy in the highest sense of that word. The fact of his having done so is matter of history. Shall I solve my own riddle? Then, have we not heard of the early Christian martyrs? Is there a doubt that they, unlettered men, slaves, weak women, even children, did exhibit, under an infinite sense of duty, issuing in infinite self-sacrifice, a heroism such as the world had never seen before; did raise the ideal of human nobleness a whole stage--rather say, a whole heaven--higher than before; and that wherever the tale of their great deeds spread, men accepted, even if they did not copy, those martyrs as ideal specimens of the human race, till they were actually worshipped by succeeding generations, wrongly, it may be, but pardonably, as a choir of lesser deities? But is there, on the other hand, a doubt that the age in which they were heroic was the most unheroic of all ages; that they were bred, lived, and died, under the most debasing of materialist tyrannies, with art, literature, philosophy, family and national life dying or dead around them, and in cities the corruption of which cannot be told for very shame--cities, compared with which Paris is the abode of Arcadian simplicity and innocence? When I read Petronius and Juvenal, and recollect that they were the contemporaries of the Apostles; when--to give an instance which scholars, and perhaps, happily, only scholars, can appreciate--I glance once more at Trimalchio's feast, and remember that within a mile of that feast St. Paul may have been preaching to a Christian congregation, some of whom--for St. Paul makes no secret of that strange fact--may have been, ere their conversion, partakers in just such vulgar and bestial orgies as those which were going on in the rich freedman's halls: after that, I say, I can put no limit to the possibility of man's becoming heroic, even though he be surrounded by a hell on earth; no limit to the capacities of any human being to form for himself or herself a high and pure ideal of human character; and, without "playing fantastic tricks before high heaven," to carry out that ideal in every-day life; and in the most commonplace circumstances, and the most menial occupations, to live worthy of--as I conceive--our heavenly birthright, and to imitate the heroes, who were the kinsmen of the gods. SUPERSTITION. A LECTURE DELIVERED AT THE ROYAL INSTITUTION, LONDON. Having accepted the very great honour of being allowed to deliver here two lectures, I have chosen as my subject Superstition and Science. It is with Superstition that this first lecture will deal.
