The false science, even that unhuman and godless science which has been already described, can only be overcome and conquered by the true. The mere method of negation--which, generally, indeed, is seldom the right one--is here, too, insufficient for the purpose. And so, in fact, when clouds of dust darken the air, or swarms of noxious insects fill it, it may suffice if the goodman of the house shuts to his casement, as he may lawfully do, even because it is his own; but when the fearful thunderstorm is lowering in the heavens, the closed window will but little insure the safety of his dwelling, unless he has more wisely provided against the danger, by a good lightning-conductor. But what is that? And how came man first to think of it? Why, by studying the electrical phenomena, and arriving at a full understanding of its nature, and so, in obedience to its laws, contriving a counteracting and diverting agent for the electric current, and converting the natural action of the threatening element into an instrument of protection. And just in the same way will a true wisdom proceed in the domain of science and truth. It is only by a good power, of a like kind and similar action to its own, that the supremacy of evil can be overcome. Even, therefore, and to this purport was the earnest warning uttered by the mouth of Truth Itself against those who, although they sat in Moses’s seat, neither went in themselves nor suffered others that were entering to go in.[45] And what a different picture does Holy Writ set before us in the noble example of Moses! No doubt the preparation for the work to which he was to be called, of leading successfully the people intrusted to him by God out of their Egyptian darkness through the fearful Red Sea and all the wanderings in the wilderness, to the borders of the promised land, was even the forty years of solitude among the noble pastoral people with whom he spent the long period of his exile. But still it is not without a deep significance that it is written that the daughter of the Egyptian monarch, having adopted the foundling of the waters, brought him up and educated him as her own son. So, too, assuredly is it not without design that it is said so emphatically of him, that he “was learned in all the wisdom of the Egyptians.”[46] In the first place, we have good reason to rejoice at and to acknowledge the comprehensive spirit and wide standard of judgment which Holy Writ here sets up. For whereas it passes a severer sentence of reprobation on the Egyptians than on any other heathen nation or people, for their moral depravity, it yet acknowledges that they possessed a scientific wisdom, which amply rewarded the labor of its acquisition, while it proved the very errors wherewith in their extreme corruption they had overloaded it, to be only the more culpable and deserving of punishment. Shallow and superficial skeptics may, indeed, as many have already done, avail themselves of such an
