This alleged signature is admittedly difficult to reconcile with the following statement by Litt: "In response to a letter from a circle of students asking whether he did not sufficiently take into account the national moment and the importance of the biological in his philosophy, Litt added a personal word in the matter [...] '... Shall I place myself under the Swastika flag, shall I raise my right hand to heaven and exclaim in an imploring and pleading voice: "Dear friends, I am with you too, I am national too! «? Don't they realise what a lack of dignity lies behind this; that morally impossible things are being demanded of me? What is demanded? They demand unconditional submission to the party programme, to all the points of the party programme! That is impossible for me, I simply cannot do that!
