aroused, the popular ignorance of the existence of higher methods of solution too dense, and the crisis too imminent for the existence of any demand for such considerations then; and the publication of the document was withheld. In it were shown the significance of Slavery as a Fact in History and a Principle in Nature; its Compensations and Advantages; its positive value, in fact, in the larger sense, in the development of human society on the planet; then its destiny to give way in our advancing civilization to the higher doctrine of abstract rights and individual culture through intellectual means; and again, the insufficiency of the latter doctrine, when taken for the whole truth; and finally, to show how, by the intervention of the science of the subject, the value of both the Principles in conflict could be extracted and made cooeperative, and their evils completely neutralized. The world not being ripe for the adoption of the superior and rational methods here intimated for the adjustment of our difficulties--the readiness of one party even, without the equal readiness of the other, being inadequate--the crisis and the conflict could not be averted; and that again being the case, it is of the utmost importance that the second in order of the two adverse principles, the principle of democracy, be completely triumphant; not because it is more true, but because it is a more _advanced_ truth, and one step nearer, therefore, to the final solution,_ which will then lap back, and subsume and assimilate and reconcile the whole family of fundamental principles upon which the existence of human society is inexpugnably based_. It is upon this lower ground of adaptation to the exigency of the age and the occasion, and as a means to the development of still higher truths, that we urge the inestimable importance of the effectual conquest over the South by the North.
