Milan Kundera said this quote

No peace is possible between the novelist and the agélaste [those who do not laugh]. Never having heard God's laughter, the agélastes are convinced that the truth is obvious, that all men necessarily think the same thing, and that they themselves are exactly what they think they are. But it is precisely in losing the certainty of truth and the unanimous agreement of others that man becomes an individual. The novel is the imaginary paradise of individuals. It is the territory where no one possesses the truth, neither Anna nor Karenin, but where everyone has the right to be understood, both Anna and Karenin.
