Beyond all doubt, the system of slavery encourages those habits and passions which make the soldier, and which instigate and maintain wars. The military spirit and that of slavery are congenial; for both belong to an early stage in the progress of civilization, when each is necessary to the support and continuance of the other. It was therefore to be expected that the Southern people would be better prepared for the organization, and also for the manoeuvring of armies. But the mistake and the fatal delusion cherished by the conspirators, was the belief that the Northern people were without manly spirit, and incapable of being aroused by sentiments of patriotism. It was an equal miscalculation to anticipate that the fabric of Northern free society would fall to pieces, and be thrown into irremediable disorder, at the first appearance of civil commotion. This false idea was the offspring of the slave system, which boasted of the solidity of its own organization and the impossibility of its overthrow. From their standpoint, amid the darkness of a social organization, in which one half the population is not more than semi-civilized, the slaveholders could not easily obtain any other view. Long accustomed to wield irresponsible power as masters, enjoying wealth and independence from the unrewarded labor of the slave, but liberal and humane, condescending and indulgent, so long as the untutored black was quiet and obedient, the planter very naturally imagined his system to be the perfection of social order. In the atmosphere of luxurious ease which surrounded him, were the elements of a mental mirage which distorted everything in his deceptive vision. He weighed the two systems, and found his own immeasurably more powerful than its antagonist. Fatal mistake! fatal but inevitable, in his condition, in the midst of the blinding refractions of the medium which enveloped him.
