This of Sans-Souci is but portion of a wider Tendency, wider set of endeavors on Friedrich's part, which returns upon him now that Peace has returned: That of improving his own Domesticities, while he labors at so many public improvements. Gazing long on that simmering "Typhoon of Marine-stores" above mentioned, we do trace Three great Heads of Endeavor in this Peace Period. FIRST, the Reform of Law; which, as above hinted, is now earnestly pushed forward again, and was brought to what was thought completion before long. With much rumor of applause from contemporary mankind. Concerning which we are to give some indications, were it only dates in their order: though, as the affair turned out not to be completed, but had to be taken up again long after, and is an affair lying wide of British ken,--there need not, and indeed cannot, be much said of it just now. SECONDLY, there is eager Furthering of the Husbandries, the Commerces, Practical Arts,--especially at present, that of Foreign Commerce, and Shipping from the Port of Embden. Which shall have due notice. And THIRDLY, what must be our main topic here, there is that of Improving the Domesticities, the Household Enjoyments such as they were;--especially definable as Renewal of the old Reinsberg Program; attempt more strenuous than ever to realize that beautiful ideal. Which, and the total failure of which, and the consequent quasi-abandonment of it for time coming, are still, intrinsically and by accident, of considerable interest to modern readers. Curious, and in some sort touching, to observe how that old original Life-Program still re-emerges on this King: "Something of melodious possible in one's poor life, is not there? A Life to the Practical Duties, yes; but to the Muses as well!"--Of Friedrich's success in his Law-Reforms, in his Husbandries, Commerces and Furtherances, conspicuously great as it was, there is no possibility of making careless readers cognizant at this day. Only by the great results--a "Prussia QUADRUPLED" in his time, and the like--can studious readers convince themselves, in a cold and merely statistic way. But in respect of Life to the Muses, we have happily the means of showing that in actual vitality; in practical struggle towards fulfillment,--and how extremely disappointing the result was. In a word, Voltaire pays his Fifth and final Visit in this Period; the Voltaire matter comes to its consummation. To that, as to one of the few things which are perfectly knowable in this Period of TEN-YEARS PEACE, and in which mankind still take interest, we purpose mostly to devote ourselves here.
