In his work on international commercial arbitration, which was published in its second edition in 2003, Aden speaks of a "traditional German national weakness of ego" that easily leads "to a German lawyer being more likely to be mistaken for a self-confident American, especially if he is, as is often the case, of Jewish origin 'having the butter taken from the bread' than vice versa".

[2] He has translated Richard Francis Burton's The Kasidah into German, as well as many poems by Alexander Pushkin, Michail Lermontow, Fjodor Tjutschew and other Russin poets.
