One of the most widespread criticisms of utilitarianism is that it cannot take rights seriously enough. Owing to the consequentialist feature, utilitarianism has room for justifying the encroachment on moral rights in the name of morality if the encroachment is required to maximize the utility. Therefore, utilitarianism come up against criticism that it cannot take moral rights seriously. Utilitarianism has responded to these right-based criticisms with Benthamite line or Millian line. Benthamite line tries to exclude the moral rights in moral discourse. Millian line tries to accommodate the moral rights in utilitarian ethical system. But they have difficulties in responding to the right-based criticisms. They cannot overcome utility-right dilemma. In order to defeat the right-based criticisms, utilitarianism need to search for new strategy which can harmonize the merits of both Benthamite line and Millian line. One method to accomplish this purpose is to adopt two-level utilitarianism which divides the levels of moral thinking into the intuitive level and the critical level. Two-level utilitarianism accepts the consequentialist feature of act utilitarianism that Benthamite line has insisted in the critical level on the one hand, and the importance of moral rights that Millian line has emphasized in the intuitive level on the other hand. In this way, two-level utilitarianism provides the method to overcome utility-right dilemma. By means of two-level strategy, utilitarianism can adhere to consequentialism that is the essential feature of consistent utilitarianism, and overcome the defects of Benthamite line, that is counterintuitiveness and self-defeatingness by introducing the merits of Millian line that it takes the rights seriously.
