We said that Lessing's dream was to be a poet. In comparison with success as a dramatist, he looked on all other achievement as inferior in kind. In. 1767 he writes to Gleim (speaking of his call to Hamburg): "Such circumstances were needed to rekindle in me an almost extinguished love for the theatre. I was just beginning to lose myself in other studies which would have made me unfit for any work of genius. My _Laocoon_ is now a secondary labor." And yet he never fell into the mistake of overvaluing what he valued so highly. His unflinching common-sense would have saved him from that, as it afterwards enabled him to see that something was wanting in him which must enter into the making of true poetry, whose distinction from prose is an inward one of nature, and not an outward one of form. While yet under thirty, he assures Mendelssohn that he was quite right in neglecting poetry for philosophy, because "only a part of our youth should be given up to the arts of the beautiful. We must practise ourselves in weightier things before we die. An old man, who lifelong has done nothing but rhyme, and an old man who lifelong has done nothing but pass his breath through a stick with holes in it,--I doubt much whether such an old man has arrived at what he was meant for."
This period of Lessing's life was a productive one, though none of its printed results can be counted of permanent value, except his share in the "Letters on German Literature." And even these must be reckoned as belonging to the years of his apprenticeship and training for the master-workman he afterwards became. The small fry of authors and translators were hardly fitted to call out his full strength, but his vivisection of them taught him the value of certain structural principles. "To one dissection of the fore quarter of an ass," says Haydon in his diary, "I owe my information." Yet even in his earliest criticisms we are struck with the same penetration and steadiness of judgment, the same firm grasp of the essential and permanent, that were afterwards to make his opinions law in the courts of taste. For example, he says of Thomson, that, "as a dramatic poet, he had the fault of never knowing when to leave off; he lets every character talk so long as anything can be said; accordingly, during these prolonged conversations, the action stands still, and the story becomes tedious." Of "Roderick Random," he says that "its author is neither a Richardson nor a Fielding; he is one of those writers of whom there are plenty among the Germans and French." We cite these merely because their firmness of tone seems to us uncommon in a youth of twenty-four. In the "Letters," the range is much wider, and the application of principles more consequent. He had already secured for himself a position among the literary men of that day, and was beginning to be feared for the inexorable justice of his criticisms. His "Fables" and his "Miss Sara Sampson" had been translated into French, and had attracted the attention of Grimm, who says of them (December, 1754): "These Fables commonly contain in a few lines a new and profound moral meaning. M. Lessing has much wit, genius, and invention; the dissertations which follow the Fables prove moreover that he is an excellent critic." In Berlin, Lessing made friendships, especially with Mendelssohn, Von Kleist, Nicolai, Gleim, and Ramler. For Mendelssohn and Von Kleist he seems to have felt a real love; for the others at most a liking, as the best material that could be had. It certainly was not of the juiciest. He seems to have worked hard and played hard, equally at home in his study and Baumann's wine-cellar. He was busy, poor, and happy.
