Closer study of the savage points to the conclusion that the civilized man falls into the same error in his regard as many adults do with respect to children, whom they fail hopelessly to interpret through lack of imagination, and to whom they are but tedious and ridiculous when they would fain be instructive and amusing; forgetting that the difference between the two stages of life is rather in the size of the toys played with, than in the way they are regarded. So too we are apt to look on foreign, and still more on savage language, symbolism, ways, and customs, as indicative of a far more radical difference and greater inferiority of mental constitution and ethical instincts than really exists. Mr. Kidd, in his book on Social Evolution, has contended with some plausibility that the brain-power of the Bushman and of the Cockney is much on a par at starting, and that the subsequent divergence is due chiefly to education and moral training; and certainly much of the evidence brought forward in Mr. Lang's volume seems to look that way. If the aboriginal Australian has a faith in the immortality of the soul and in a supreme God, the rewarder of righteousness, if he summarizes the laws of God under the precept of unselfishness; if in all this he is but a type of the universal savage, surely it were well if some of the missionary zeal which is devoted to supplying the heathen with Bibles which they cannot understand, were turned to the work of bringing our own godless millions up to their religious level.
