 Parfit’s convergence argument has not attracted as much attention as other aspects of either his work or Scanlon’s. (One exception is Kumar 2011.) However, the general issue of the relationship between contractualism and consequentialism is very relevant to a number of objections to contractualism. It is always worth arking whether contractualism can cope adequately with new challenges (such as aggregation, substantive responsibility, risk, or future people) without collapsing into rule consequentialism.
