What exactly did these words, of both the and the Gettysburg Address, mean? They meant that there was no difference, between one human being, and another human being, that made one the master and the other the servant. As Jefferson once put it, some men are not born with saddles on their backs, nor are others born booted and spurred to ride them. That a man or woman rides a horse corresponds with the difference in their natures. No injustice is done to the horse! That an ox should pull a plow, while a man walks behind, is according to nature. In these cases, servitude follows from the laws of nature. But these same laws of nature tell us that when a human being is subjected to other human beings as if he were a horse or an ox, the laws of nature are violated. All human beings are accordingly equal in their right not to be enslaved, and in their right to be in secure possession of their lives, liberties, and property. To this end they have a right to be governed only by laws to which they have consented.
