 Alkan 's later correspondence contains many <unk> comments . In a letter of about 1861 he wrote to Hiller : " I 'm becoming daily more and more <unk> and <unk> ... nothing worthwhile , good or useful to do ... no one to devote myself to . My situation makes me <unk> sad and <unk> . Even musical production has lost its attraction for me for I can 't see the point or goal . " This spirit of <unk> may have led him to reject requests in the 1860s to play in public , or to allow performances of his orchestral compositions . However , it should not be ignored that he was writing similarly <unk> self @-@ analyses in his letters of the early 1830s to Masarnau .
