I do not know by what extraordinary mental accident modern writers so constantly connect the idea of progress with the idea of independent thinking. Progress is obviously the antithesis of independent thinking. For under independent or individualistic thinking, every man starts at the beginning, and goes, in all probability, just as far as his father before him. But if there really be anything of the nature of progress, it must mean, above all things, the careful study and assumption of the whole of the past.
