His greatest book is perhaps the _Frederick_, the biography of a hero reduced more than once to such extremities that apparently nothing but some miraculous intervention could save him, and who did not yield, but struggled on and finally emerged victorious. When we consider Frederick’s position during the last part of the Seven Years’ War, we must admit that no man was ever in such desperate circumstances or showed such uncrushable determination. It was as if the Destinies, in order to teach us what human nature can do, had ordained that he who had the most fortitude should also encounter the severest trial of it. Over and over again Frederick would have been justified in acknowledging defeat, and we should have said that he had done all that could be expected even of such a temper as that with which he was endowed. If the struggle of the will with the encompassing world is the stuff of which epics are made, then no greater epic than that of _Frederick_ has been written in prose or verse, and it has the important advantage of being true. It is interesting to note how attractive this primary virtue of which Frederick is such a remarkable representative is to Carlyle, how _moral_ it is to him; and, indeed, is it not the sum and substance of all morality? It should be noted also that it was due to no religious motive: that it was bare, pure humanity. At times it is difficult not to believe that Carlyle, notwithstanding his piety, loves it all the more on that account. It is strange that an example so salutary and stimulating to the poorest and meanest of us should be set by an unbelieving king, and that my humdrum existence should be secretly supported by “Frederick II. Roi de Prusse.” * * *
