If, on the contrary, subdued by its wants, man allows himself to be governed without reserve by the instinct of nature, it is his interior autonomy that vanishes, and with it all trace of this autonomy is exteriorly effaced. The animal nature is alone visible upon his visage; the eye is watery and languishing, the mouth rapaciously open, the voice trembling and muffled, the breathing short and rapid, the limbs trembling with nervous agitation: the whole body by its languor betrays its moral degradation. Moral force has renounced all resistance, and physical nature, with such a man, is placed in full liberty. But precisely this complete abandonment of moral independence, which occurs ordinarily at the moment of sensuous desire, and more still at the moment of enjoyment, sets suddenly brute matter at liberty which until then had been kept in equilibrium by the active and passive forces. The inert forces of nature commence from thence to gain the upper hand over the living forces of the organism; the form is oppressed by matter, humanity by common nature. The eye, in which the soul shone forth, becomes dull, or it protrudes from its socket with I know not what glassy haggardness; the delicate pink of the cheeks thickens, and spreads as a coarse pigment in uniform layers. The mouth is no longer anything but a simple opening, because its form no longer depends upon the action of forces, but on their non-resistance; the gasping voice and breathing are no more than an effort to ease the laborious and oppressed lungs, and which show a simple mechanical want, with nothing that reveals a soul. In a word, in that state of liberty which physical nature arrogates to itself from its chief, we must not think of beauty. Under the empire of the moral agent, the liberty of form was only restrained, here it is crushed by brutal matter, which gains as much ground as is abstracted from the will. Man in this state not only revolts the moral sense, which incessantly claims of the face an expression of human dignity, but the _æsthetic_ sense, which is not content with simple matter, and which finds in the form an unfettered pleasure—the æsthetic sense will turn away with disgust from such a spectacle, where _concupiscence_ could alone find its gratification.
