Lessing's own views of dogmatic religion are to be found in his work entitled, "The Education of the Human Race." These views have since so far become the veriest commonplaces of criticism, that one can hardly realize that, only ninety years ago, they should have been regarded as dangerous paradoxes. They may be summed up in the statement that all great religions are good in their time and place; that, "as there is a soul of goodness in things evil, so also there is a soul of truth in things erroneous." According to Lessing, the successive phases of religious belief constitute epochs in the mental evolution of the human race. So that the crudest forms of theology, even fetishism, now to all appearance so utterly revolting, and polytheism, so completely inadequate, have once been the best, the natural and inevitable results of man's reasoning powers and appliances for attaining truth. The mere fact that a system of religious thought has received the willing allegiance of large masses of men shows that it must have supplied some consciously felt want, some moral or intellectual craving. And the mere fact that knowledge and morality are progressive implies that each successive system may in due course of time be essentially modified or finally supplanted. The absence of any reference to a future state of retribution, in the Pentateuch and generally in the sacred writings of the Jews, and the continual appeal to hopes and fears of a worldly character, have been pronounced by deists an irremediable defect in the Jewish religion. It is precisely this, however, says Lessing, which constitutes one of its signal excellences. "That thy days may be long in the land which Jehovah thy God giveth thee," was an appeal which the uncivilized Jew could understand, and which could arouse him to action; while the need of a future world, to rectify the injustices of this, not yet being felt, the doctrine would have been of but little service. But in later Hebrew literature, many magnificent passages revealed the despair felt by prophet and thinker over the insoluble problem presented by the evil fate of the good and the triumphant success of the wicked; and a solution was sought in the doctrine of a Messianic kingdom, until Christianity with its proclamation of a future life set the question entirely aside. By its appeal to what has been aptly termed "other-worldliness," Christianity immeasurably intensified human responsibility, besides rendering clearer its nature and limits. But according to Lessing, yet another step remains to be taken; and here we come upon the gulf which separates him from men of the stamp of Theodore Parker. For, says Lessing, the appeal to unearthly rewards and punishments is after all an appeal to our lower feelings; other-worldliness is but a refined selfishness; and we are to cherish virtue for its own sake not because it will lead us to heaven. Here is the grand principle of Stoicism. Lessing believed, with Mr. Mill, that
