"Sad, sad, sad! ... a name that will leave a most powerful impression on the history of art." (The Lives of the Great Composers)
"He invariably chooses, unnecessarily, the untrodden path, attempting to fly where a rational person would walk with better results"「彼(ワーグナー)は判で押したような、無駄だらけで、勝手気ままなやり方ばかりを選び、理性的な人物ならばより良い結果を求めて着実に歩みを進めるところなのに、まるで跳びはねるような真似をするのが好きなようだ」(The Lives of the Great Composers)
