"Stepan Arkadyevitch had not chosen his political opinions or his views; these political opinions and views had come to him of themselves, just as he did not choose the shapes of his hat and coat, but simply took those that were being worn. And for him, living in a certain society—owing to the need, ordinarily developed at years of discretion, for some degree of mental activity—to have views was just as indispensable as to have a hat."
