[Sidenote: _Eclecticism and sensationalism. E. Platner._] It is impossible to classify works of such calibre, almost wholly lacking as they are in scientific method; on each page their writers pass from physiological sensationalism to moralism; from the imitation of nature to mysticism and transcendent finalism without the slightest sense of incongruity. It would be absurd to take them seriously; in comparison it is almost refreshing to come across a frank hedonist in the German, Ernst Plainer, who interpreted Hogarth's inquiry into lines after a fashion of his own and was unable to see anything in æsthetic facts except a reverberation of sexual pleasure. Where can we find a beauty, he asks, that is not derived from the female figure, the centre of all beauty? Undulating lines are beautiful because found in a woman's body; beautiful are all movements distinctively feminine; beautiful the tones of music melting one into another; beautiful the poem where one thought embraces another with tenderness and facility.[14] Condillac's sensationalism had already shown itself wholly incapable of understanding æsthetic productivity; the associationism especially promoted by the work of Hume fared no better. [Sidenote: _Fr. Hemsterhuis._] The Dutchman Hemsterhuis considered beauty as a phenomenon born of the meeting between sensibility, which gives multiplicity, and the internal sense, which tends to unity; hence the beautiful is "that which exhibits the greatest number of ideas in the shortest time." Man, to whom it is not permitted to attain ultimate unity, finds in beauty an approximate unity which gives him a pleasure somewhat analogous with the joy of love. This theory of Hemsterhuis, in which elements of mysticism and sensationalism mingle with glimpses of truth, developed later into the sentimentalism of Jacobi, for whom the totality of Truth and Goodness and even the Supersensible itself are sensibly present to the soul in the form of beauty.[15] [Sidenote: _Neo-Platonism and mysticism. Winckelmann._] Platonism or, more accurately, neo-Platonism was revived by the creator of the history of figurative art, Winckelmann (1764). Contemplation of the masterpieces of antique plastic art, and the impression of superhuman loftiness and divine indifference which they create all the more irresistibly because we cannot reawaken the life they once possessed or understand their real significance, led Winckelmann, and others with him, to the conception of a Beauty which, descending from the seventh heaven of the divine Idea, embodied itself in works of this description. Baumgarten's follower Mendelssohn had denied the enjoyment of beauty to God: the neo-Platonist Winckelmann gave it back to him and lodged it in his bosom.
