Strictly speaking, there were three stages in the development of the anti-slavery sentiment leading up to the Civil War. There was the period of indifference, from 1759 to 1830, when the North winked at slavery, ignored the traffic and avoided the whole subject. There was the epoch of agitation, from 1831 to 1850, when Garrison and his friends insisted upon "the immediate and unconditional emancipation of the slaves on the soil," and the agitation was kept up by men who "would not retreat, who would not equivocate, who would not be silent and who would be heard." Then came the stage when men tried legislative palliatives; when all manner of political medicaments and poultices were tried as cures, which were about as effective in destroying the poison as a porous plaster would be to draw out the fire from a volcano. For more than sixty years a veil had hung before men's minds, and it was as if they saw slaves as trees walking, in an unreal world. The sea captain fears a fog more than an equinoctial storm. When the mist falls, and obscures the glass, and the ship is surrounded with white darkness, and the surf is thundering on some Nantucket, as a graveyard of the sea, the captain longs for a cold, sharp wind out of the North, to cut the fog and bring out the stars and sun. And not otherwise was it with the great debate between Lincoln and Douglas--it lifted the veil from men's eyes, it swept the fog out of the air, it made the issue clear. Then it was that for the first time the North saw that the conflict was inevitable, because the Union could not endure permanently, half slave and half free; saw that liberty and slavery were as irreconcilable as day and night. Before considering the influence of Lincoln's clear thinking and speaking upon the eternal principles of right, we must note the general reawakening of the popular intelligence which preceded it, and which was due to two causes, the panic of 1857 and the religious revival which swept over the land during the same year. As the Northern merchant began to see that the South had determined to secede and try her fate alone, he became afraid to sell his goods to Southern customers. The Northern manufacturer, in turn, was overstocked, and if the banker called his loans there was no response, for the chain was broken; the result was the panic of 1857. Hunger and Want stalked through the land--Winter and Poverty became bosom friends. Black despair fell upon the people and in the hour of need they cried unto God, and God heard them. When a nation prospers and grows rich, religion languishes. When nations enter upon disaster and peril, the people turn unto God. Abundance enervates. Morals always sink to a low level when men's eyes stand out with fatness.
