A little man in spectacles, with a narrow forehead, tore himself from the discussion for an instant to greet Levin, and then went on talking without paying any further attention to him. Levin sat down to wait till the professor should go, but he soon began to get interested in the subject under discussion.

Levin had come across the magazine articles about which they were disputing, and had read them, interested in them as a development of the first principles of science, familiar to him as a natural science student at the university. But he had never connected these scientific deductions as to the origin of man as an animal, as to reflex action, biology, and sociology, with those questions as to the meaning of life and death to himself, which had of late been more and more often in his mind.
