It is therefore not going far enough to say that the light of the understanding only deserves respect when it reacts on the character; to a certain extent it is from the character that this light proceeds; for the road that terminates in the head must pass through the heart. Accordingly, the most pressing need of the present time is to educate the sensibility, because it is the means, not only to render efficacious in practice the improvement of ideas, but to call this improvement into existence. LETTER IX. But perhaps there is a vicious circle in our previous reasoning! Theoretical culture must it seems bring along with it practical culture, and yet the latter must be the condition of the former. All improvement in the political sphere must proceed from the ennobling of the character. But, subject to the influence of a social constitution still barbarous, how can character become ennobled? It would then be necessary to seek for this end an instrument that the state does not furnish, and to open sources that would have preserved themselves pure in the midst of political corruption. I have now reached the point to which all the considerations tended that have engaged me up to the present time. This instrument is the art of the beautiful; these sources are open to us in its immortal models. Art, like science, is emancipated from all that is positive, and all that is humanly conventional; both are completely independent of the arbitrary will of man. The political legislator may place their empire under an interdict, but he cannot reign there. He can proscribe the friend of truth, but truth subsists; he can degrade the artist, but he cannot change art. No doubt, nothing is more common than to see science and art bend before the spirit of the age, and creative taste receive its law from critical taste. When the character becomes stiff and hardens itself, we see science severely keeping her limits, and art subject to the harsh restraint of rules; when the character is relaxed and softened, science endeavors to please and art to rejoice. For whole ages philosophers as well as artists show themselves occupied in letting down truth and beauty to the depths of vulgar humanity. They themselves are swallowed up in it; but, thanks to their essential vigor and indestructible life, the true and the beautiful make a victorious fight, and issue triumphant from the abyss.
