How momentous a disadvantage this is, we can best know by contemplating the characters which have sometimes lighted up the old times. Men were then devoutly persuaded that their eternal salvation depended on their having true beliefs. Any slackness in finding out which beliefs are the true ones would have to be answered for before the throne of Almighty God, at the sure risk and peril of everlasting damnation. To what quarter in the large historic firmament can we turn our eyes with such certainty of being stirred and elevated, of thinking better of human life and the worth of those who have been most deeply penetrated by its seriousness, as to the annals of the intrepid spirits whom the protestant doctrine of indefeasible personal responsibility brought to the front in Germany in the sixteenth century, and in England and Scotland in the seventeenth? It is not their fanaticism, still less is it their theology, which makes the great Puritan chiefs of England and the stern Covenanters of Scotland so heroic in our sight. It is the fact that they sought truth and ensued it, not thinking of the practicable nor cautiously counting majorities and minorities, but each man pondering and searching so 'as ever in the great Taskmaster's eye.' It is no adequate answer to urge that this awful consciousness of a divine presence and supervision has ceased to be the living fact it once was. That partly explains, but it certainly does not justify, our present lassitude. For the ever-wakeful eye of celestial power is not the only conceivable stimulus to responsibility. To pass from those grim heroes of protestantism to the French philosophers of the last century is a wide leap in a hundred respects, yet they too were pricked by the oestrus of intellectual responsibility. Their doctrine was dismally insufficient, and sometimes, as the present writer has often pointed out, it was directly vicious. Their daily lives were surrounded by much shabbiness and many meannesses. But, after all, no temptation and no menace, no pains or penalties for thinking about certain subjects, and no rewards for turning to think about something else, could divert such men as Voltaire and Diderot from their alert and strenuous search after such truth as could be vouchsafed to their imperfect lights. A catastrophe followed, it is true, but the misfortunes which attended it were due more to the champions of tradition and authority than to the soldiers of emancipation. Even in the case of the latter, they were due to an inadequate doctrine, and not at all either to their sense of the necessity of free speculation and inquiry, or to the intrepidity with which they obeyed the promptings of that ennobling sense.
