«Each department of knowledge passes through three stages. The theoretic stage; the theological stage and the metaphysical or abstract stage.»

«Though the practice of chivalry fell even more sadly short of its theoretic standard than practice generally falls below theory, it remains one of the most precious monuments of the moral history of our race, as a remarkable instance of a concerted and organized attempt by a most disorganized and distracted society, to raise up and carry into practice a moral ideal greatly in advance of its social condition and institutions; so much so as to have been completely frustrated in the main object, yet never entirely inefficacious, and which has left a most sensible, and for the most part a highly valuable impress on the ideas and feelings of all subsequent times.»
