Schapiro writes that Kunitsyn’s influence on Pushkin’s political views was 'important above all.' Schapiro describes Kunitsyn's philosophy as conveying 'the most enlightened principles of past thought on the relations of the individual and the state,' namely, that the ruler’s power is 'limited by the natural rights of his subjects, and these subjects can never be treated as a means to an end but only as an end in themselves.'
