451 (return) [ It was this which rendered the wars so sanguinary, and the battles so obstinate. The immortal Robertson, in an excellent discourse on the state of the world at the period of the establishment of Christianity, has traced a picture of the melancholy effects of slavery, in which we find all the depth of his views and the strength of his mind. I shall oppose successively some passages to the reflections of Gibbon. The reader will see, not without interest, the truths which Gibbon appears to have mistaken or voluntarily neglected, developed by one of the best of modern historians. It is important to call them to mind here, in order to establish the facts and their consequences with accuracy. I shall more than once have occasion to employ, for this purpose, the discourse of Robertson. “Captives taken in war were, in all probability, the first persons subjected to perpetual servitude; and, when the necessities or luxury of mankind increased the demand for slaves, every new war recruited their number, by reducing the vanquished to that wretched condition. Hence proceeded the fierce and desperate spirit with which wars were carried on among ancient nations. While chains and slavery were the certain lot of the conquered, battles were fought, and towns defended with a rage and obstinacy which nothing but horror at such a fate could have inspired; but, putting an end to the cruel institution of slavery, Christianity extended its mild influences to the practice of war, and that barbarous art, softened by its humane spirit, ceased to be so destructive. Secure, in every event, of personal liberty, the resistance of the vanquished became less obstinate, and the triumph of the victor less cruel. Thus humanity was introduced into the exercise of war, with which it appears to be almost incompatible; and it is to the merciful maxims of Christianity, much more than to any other cause, that we must ascribe the little ferocity and bloodshed which accompany modern victories.”—G.]
