In saying that constant re-origination is the method of Nature, I do not overlook the element nor underrate the importance of Imitation. This it is that secures continuity, connection, and structural unity. By vital imitation the embryonic man assumes the features and traits of his progenitors. After birth the infant remains in the matrix of the household; after infancy the glowing youth is held in that of society; and processes kindred with those which bestowed likeness to father and mother go on to assimilate him with a social circle or an age. Complaint is made, and by good men, of that implicit acquiescence which keeps in existence Islam, Catholicism, and the like, long after their due time has come to die; yet, abolish the law of imitation which causes this, and the immediate disintegration of mankind will follow. Mortar is much in the way, when we wish to take an old building to pieces and make other use of the bricks; do you therefore advise its disuse? But imitation would preserve nothing, did not the law of re-origination keep it company. We are not born from our parents alone, but from the loins of eternal Nature no less. Was Orpheus the grandson of Zeus and Mnemosyne,--of sovereign Unity and immortal Memory? Equally is Shakspeare and every genuine bard. Could the heroes of old Greece trace their derivation from the gods? Little of a hero is he, even in these times of ours, who is not of the like lineage. And indeed, one and all, we have a father and mother whose marriage-morn is of more ancient date than our calendars, and of whose spousal solemnities this universe is the memorial. All life, indeed, whatsoever be its form and rank, has, along with connections of pedigree and lateral association, one tap-root that strikes straight down into the eternal.
