“I have given up the struggle for the ‘superman’—I could reach him now and then, but not lastingly [...]. You wrote in a recent letter that we drift apart—perhaps, but there is such a deep difference in principle between us:—the other day I read Nietzsche’s ‘Birth of Tragedy’ and then I thought of you and I felt things clearer; read it some day if you do not know it. You are Dionysus and I am Apollinius and the world we live in is Alexanderinius.

— C.S. Adama van Scheltema to L.E.J. Brouwer, 1907.”
