Abstract
The recently published story by D. Granin entitled Aurochs [Zubr] presents the recollections of N. V. Timofeev-Resovskii on Moscow University in the first years after the revolution. In his account, an interesting philosophical circle was active there at the time: "The logical and philosophical circle was headed by Gustav Gustavovich Shpet, who unsettled minds with unprecedented paradoxes and shook the most unshakeable foundations of this world, and Nikolai Nikolaevich Luzin, a great mathematician who was able to find a philosophical meaning in mathematics." V. Kaverin also tells about the tremendous impression made on him by a lecture Shpet gave in 1919 at the Faculty of History and Philology of Moscow University
