All the lineaments which providence traces on the surface of a nation have their parallels, sombre but distinct, in their depths, and all convulsions of the depths produce ebullitions on the surface. True history being a mixture of all things, the true historian mingles in everything.
Man is not a circle with a single centre; he is an ellipse with a double focus. Facts form one of these, and ideas the other.
