world were to continue under its existing dispensation, and the powers which have just been granted to us were to be continued through myriads of future ages. § III. It seems to me, then, that the whole human race, so far as their own reason can be trusted, may at present be regarded as just emergent from childhood; and beginning for the first time to feel their strength, to stretch their limbs, and explore the creation around them. If we consider that, till within the last fifty years, the nature of the ground we tread on, of the air we breathe, and of the light by which we see, were not so much as conjecturally conceived by us; that the duration of the globe, and the races of animal life by which it was inhabited, are just beginning to be apprehended; and that the scope of the magnificent science which has revealed them, is as yet so little received by the public mind, that presumption and ignorance are still permitted to raise their voices against it unrebuked; that perfect veracity in the representation of general nature by art has never been attempted until the present day, and has in the present day been resisted with all the energy of the popular voice;[46] that the simplest problems of social science are yet so little understood, as that doctrines of liberty and equality can be openly preached, and so successfully as to affect the whole body of the civilized world with apparently incurable disease; that the first principles of commerce were acknowledged by the English Parliament only a few months ago, in its free trade measures, and are still so little understood by the million, that no nation dares to abolish its custom-houses;[47] that the simplest principles of policy are still not so much as stated, far less received, and that civilized nations persist in the belief that the subtlety and dishonesty which they know to be ruinous in dealings between man and man, are serviceable in dealings between multitude and multitude; finally, that the scope of the Christian religion, which we have been taught for two thousand years, is still so little conceived by us, that we suppose the laws of charity and of self-sacrifice bear upon individuals in all their social relations, and yet do not bear upon nations in any of their political relations;--when, I say, we thus review the depth of simplicity in which the human race are still plunged with respect to all that it most profoundly concerns them to know, and which might, by them, with most ease have been ascertained, we can hardly determine how far back on the narrow path of human progress we ought to place the generation to which we belong, how far the swaddling clothes are unwound from us, and childish things beginning to be put away.
