Anna Karenina Part 3, Chapters 1-3

Levin's half-brother Sergey comes to visit. Whenever Levin and Sergey get together, they debate politics and intellectual issues for hours. Levin comes to realize this time that Sergey, a city man himself, has a rather distorted view of peasants, nature and the countryside in general. To Sergey, the peasants are worth little.

"To Konstantin, the peasant was simply the chief partner in their common labor." Part 3, Chapter 1, pg. 251

Further, Sergey argues everything in his life intellectually; he never brings his heart or his emotions into the matter. It makes him seem devoid of something. For Levin, a man always searching for answers and spiritual development, this approach is not satisfactory. The road to knowledge can never be purely intellectual--it needs to have heart. Kitty would agree with this perspective.
