commenting on and offering criticism of a recent publication by the Beethoven scholar A. W. Thayer, which exposed the bogus nature of much writing about Beethoven, referring to his own reminiscences of Beethoven, Aus dem Schwarzspanierhaus, rejecting on the basis of his and his father's close acquaintance of Beethoven the description of the composer as "crazy [närrisch]", correcting Thayer on many points, including in his view of Beethoven's relations with his brother Johann, remarking on the dubious nature of Johann's business dealings, recalling Johann's importunate meddling in Beethoven's affairs, describing Johann as the least unpleasant of Beethoven's relations, contradicting Thayer flatly in his assertion that Johann was appreciative of Beethoven's music, noting his description of it as "incomprehensible, foolish, crazy stuff", remarking on Beethoven's constant laments regarding Johann and his nephew Carl, noting that Thayer for all his researches was not personally acquainted with Beethoven, as he was, nor with Beethoven's nephew and Schindler, regretting that Thayer did not discusses his views with him before publication, remarking that Beethoven was indeed a very weak character, highly dependent on others on account of his deafness and lack of ability in dealing with practical matters, commenting on the baleful influence in Beethoven's life exerted by his other brother, Caspar, referring to Beethoven's wishes to be married, his frequent changes of address, and many other matters
