It will be understood why I formerly said in the chapter respecting ideas of beauty, that those ideas were the subject of moral and not of intellectual, nor altogether of sensual perception; and why I spoke of the pleasures connected with them as derived from "those material sources which are agreeable to our moral nature in its purity and perfection." For, as it is necessary to the existence of an idea of beauty, that the sensual pleasure which may be its basis, should be accompanied first with joy, then with love of the object, then with the perception of kindness in a superior Intelligence, finally with thankfulness and veneration towards that Intelligence itself, and as no idea can be at all considered as in any way an idea of beauty, until it be made up of these emotions, any more than we can be said to have an idea of a letter of which we perceive the perfume and the fair writing, without understanding the contents of it, or intent of it; and as these emotions are in no way resultant from, nor obtainable by, any operation of the intellect, it is evident that the sensation of beauty is not sensual on the one hand, nor is it intellectual on the other, but is dependent on a pure, right, and open state of the heart, both for its truth and for its intensity, insomuch that even the right after action of the intellect upon facts of beauty so apprehended, is dependent on the acuteness of the heart feeling about them; and thus the Apostolic words come true, in this minor respect as in all others, that men are alienated from the life of God, through the ignorance that is in them, having the understanding darkened because of the hardness of their hearts, and so being past feeling, give themselves up to lasciviousness; for we do indeed see constantly that men having naturally acute perceptions of the beautiful, yet not receiving it with a pure heart, nor into their hearts at all, never comprehend it, nor receive good from it, but make it a mere minister to their desires, and accompaniment and seasoning of lower sensual pleasures, until all their emotions take the same earthly stamp, and the sense of beauty sinks into the servant of lust.
