In what the point of his theory lay, Levin did not understand, because he did not take the trouble to understand.
He put this down to his own credit, unaware that Metrov, who had already discussed his theory over and over again with all his intimate friends, talked of it with special eagerness to every new person, and in general was eager to talk to anyone of any subject that interested him, even if still obscure to himself.

This doctrine, if true, would be absolutely fatal to my theory.

To make this theory concrete, let us suppose that you are thinking of St.
