  Like Bentham, Mill sought to use utilitarianism to inform law and social policy. The aim of increasing happiness underlies his arguments for women's suffrage and free speech. We can be said to have certain rights, then — but those rights are underwritten by utility. If one can show that a purported right or duty is harmful, then one has shown that it is not genuine. One of Mills most famous arguments to this effect can be found in his writing on women's suffrage when he discusses the ideal marriage of partners, noting that the ideal exists between individuals of “cultivated faculties” who influence each other equally. Improving the social status of women was important because they were capable of these cultivated faculties, and denying them access to education and other opportunities for development is forgoing a significant source of happiness. Further, the men who would deny women the opportunity for education, self-improvement, and political expression do so out of base motives, and the resulting pleasures are not ones that are of the best sort.
