Exploring the ramifications of the philosophical applications to foreign affairs, Souffrant paves the way to the construction of a philosophy of inter- and trans-national relations. He offers an analysis of a consistent approach to the applications of ethics and international affairs. It demonstrates the manner in which, for J.S. Mill, social philosophy is linked to international philosophy. Souffrant argues that Mill's support of colonization is consistent with his overall philosophy of international relations but demonstrates that only an additional independent analysis of colonization could find fault with both Mill's argument for and his support of colonization. Souffrant concludes with the claims that Mill's philosophy of international relations extends his social and political philosophy and that an ethics of international affairs privileges, fundamentally, a concept of group responsibility.
