This chapter offers an account of individual rights and agency, and it considers both the liberal dimension and the communitarian dimension of public health ethics. It examines the relationship between social justice and social epidemiology and offers a particular interpretation of social justice as being crucially informed by a relational ethics of mutuality and solidarity. It provides a study premised on the hypothesis that relational theorizing and conceptualization developed in ecological epidemiology has its analogue in ethics. The chapter discusses how relational theorizing in both ethics and epidemiology can provide a promising pathway to a critical public health ethics. It considers the philosophy of epidemiology and the constitutive concepts guiding relational or social theorizing in the field.
