All the vast labour of European erudition has not been able to replace its utility. At every step we are obliged to differ from it, but at every step we are obliged to use it. It is a necessary springing-board, or a stair that we have to use for entrance, though we must leave it behind if we wish to pass forwards into the penetralia."
