For, to speak out once for all, man only plays when in the full meaning of the word he is a man, and _he is only completely a man when he plays_. This proposition, which at this moment perhaps appears paradoxical, will receive a great and deep meaning if we have advanced far enough to apply it to the twofold seriousness of duty and of destiny. I promise you that the whole edifice of æsthetic art and the still more difficult art of life will be supported by this principle. But this proposition is only unexpected in science; long ago it lived and worked in art and in the feeling of the Greeks, her most accomplished masters; only they removed to Olympus what ought to have been preserved on earth. Influenced by the truth of this principle, they effaced from the brow of their gods the earnestness and labor which furrow the cheeks of mortals, and also the hollow lust that smoothes the empty face. They set free the ever serene from the chains of every purpose, of every duty, of every care, and they made _indolence_ and _indifference_ the envied condition of the godlike race; merely human appellations for the freest and highest mind. As well the material pressure of natural laws as the spiritual pressure of moral laws lost itself in its higher idea of necessity, which embraced at the same time both worlds, and out of the union of these two necessities issued true freedom. Inspired by this spirit the Greeks also effaced from the features of their ideal, together with _desire or inclination_, all traces of _volition_, or, better still, they made both unrecognizable, because they knew how to wed them both in the closest alliance. It is neither charm, nor is it dignity, which speaks from the glorious face of Juno Ludovici; it is neither of these, for it is both at once. While the female god challenges our veneration, the godlike woman at the same time kindles our love. But while in ecstacy we give ourselves up to the heavenly beauty, the heavenly self-repose awes us back. The whole form rests and dwells in itself—a fully complete creation in itself—and as if she were out of space, without advance or resistance; it shows no force contending with force, no opening through which time could break in. Irresistibly carried away and attracted by her womanly charm, kept off at a distance by her godly dignity, we also find ourselves at length in the state of the greatest repose, and the result is a wonderful impression for which the understanding has no idea and language no name.
