Thanks, axon I wasn't aware of that.
This is the discussion, right? The main reason I think Turgenev and Dostoevsky quarreled was because Turgenev idealized a confident, realistic character that is the opposite of what Dostoevsky idealized in Notes From the Underground. There's also the fact that throughout most of his life, Turgenev lived in Europe, basically forgetting his homeland, and developing a writing style similar to European authors.
