Katavasov was very fond of discussing metaphysics , having derived his notions from natural science writers who had never studied metaphysics , and in Moscow Levin had had many arguments with him of late .
Катавасов очень любил рассуждать о метафизике, заимствуя свои понятия у писателей-естествоиспытателей, никогда не занимавшихся метафизикой, и в Москве Левин в последнее время много спорил с ним.
