Certainly there was no want of Literary Men discernible from Reinsberg at that time; and the young Prince corresponds with a good many of them; temporal potentate saluting spiritual, from the distance,--in a way highly interesting to the then parties, but now without interest, except of the reflex kind, to any creature. A very cold and empty portion, this, of the Friedrich Correspondence; standing there to testify what his admiration was for literary talent, or the great reputation of such; but in itself uninstructive utterly, and of freezing influence on the now living mind. Most of those French lights of the then firmament are gone out. Forgotten altogether; or recognized, like Rollin and others, for polished dullards, university big-wigs, and long-winded commonplace persons, deserving nothing but oblivion. To Montesquieu,--not yet called "Baron de Montesquieu" with ESPRIT DES LOIS, but "M. de Secondat" with (Anonymous) LETTRES PERSANES, and already known to the world for a person of sharp audacious eyesight,--it does not appear that Friedrich addressed any Letter, now or afterwards. No notice of Montesquieu; nor of some others, the absence of whom is a little unexpected. Probably it was want of knowledge mainly; for his appetite was not fastidious at this time. And certainly he did hit the centre of the mark, and get into the very kernel of French literature, when, in 1736, hardly yet established in his new quarters, he addressed himself to the shining figure known to us as "Arouet Junior" long since, and now called M. DE VOLTAIRE; which latter is still a name notable in Friedrich's History and that of Mankind. Friedrich's first Letter, challenging Voltaire to correspondence, dates itself 8th August, 1736; and Voltaire's Answer--the Reinsberg Household still only in its second month--was probably the brightest event which had yet befallen there.
