"Scriabin always said that everything within his later compositions was strictly according to 'law.' He said that he could prove this fact. However, everything seemed to conspire against his giving a demonstration. One day he invited Taneyev and I to his apartment so he could explain his theories of composition. We arrived and he dilly-dallied for a long time. Finally, he said he had a headache and would explain it all another day. That 'another day' never came."
