Luther, Milton, and Goethe: these are very strange names to bring together. It strikes us, however, that the effect may not be uninteresting if we connect the names of those three great men, as having each represented to us the Principle of Evil, and each represented him in a different way. Each of the three has left on record his conception of a great accursed being, incessantly working in human affairs, and whose function it is to produce evil. There is nothing more striking about Luther than the amazing sincerity of his belief in the existence of such an evil being, the great general enemy of mankind, and whose specific object, in Luther's time, it was to resist Luther's movement, and, if possible, "cut his soul out of God's mercy." What was Luther's exact conception of this being is to be gathered from his life and writings. Again, we have Milton's Satan. Lastly, we have Goethe's Mephistopheles. Nor is it possible to confound the three, or for a moment to mistake the one for the other. They are as unlike as it is possible for three grand conceptions of the same thing to be. May it not, then, be profitable to make their peculiarities and their differences a subject of study? Milton's Satan and Goethe's Mephistopheles have indeed been frequently contrasted in a vague, antithetic way; for no writer could possibly give a description of Goethe's Mephistopheles without saying something or other about Milton's Satan. The exposition, however, of the difference between the two has never been sufficient; and it may give the whole speculation greater interest if, in addition to Milton's Satan and Goethe's Mephistopheles, we include Luther's Devil. It is scarcely necessary to premise that here there is to be no theological discussion. All that we propose is to compare, as we find them, three very striking delineations of the Evil Principle, one of them experimental, the other two poetical. * * * * *
