'When I concern myself with Roithamer, with what order of magnitude am I dealing? I ask myself, clearly I am dealing with a head that is willing and compelled to go to extremes in everything he does and capable, in this reciprocity of intellectual interaction, of peak record performances, a man who takes his own development, the development of his character and of his inborn intellectual gifts to its utmost peak, its utmost limits, its highest degree of realization . . . and who must force everything he is, in the final analysis, to coalesce in one extreme point, force it all to the utmost limits of his intellectual capacity and his nervous tension until, at the highest degree of such expansion and contraction and the total concentration he has repeatedly achieved, he must actually be torn apart.'
