So that if I owed to Bloch—for his "good tidings" that beauty and the enjoyment of beauty were not inaccessible things, and that we have acted foolishly in renouncing them for all time—a debt of gratitude of the same kind that we owe to an optimistic physician or philosopher who has given us reason to hope for length of days in this world and not to be entirely cut off from it when we shall have passed beyond the veil, the houses of assignation which I began to frequent some years later—by furnishing me with specimens of beauty, by allowing me to add to the beauty of women that element which we are powerless to invent, which is something more than a mere summary of former beauties, that present indeed divine, the one present that we cannot bestow upon ourselves, before which faint and fail all the logical creations of our intellect, and which we can seek from reality alone: an individual charm—deserved to be ranked by me with those other benefactors more recent in origin but of comparable utility (before finding which we used to imagine without any warmth the seductive charms of Mantegna, of Wagner, of Siena, by studying other painters, hearing other composers, visiting other cities): namely illustrated editions of the history of painting, symphonic concerts and handbooks to 'Mediaeval Towns'.
