Abstract

Epigenetics reveals the biological mechanisms underlying the reproduction and even the transmission of social inequalities in health. It also emphasizes the complexity of factors involved in the development of some diseases. This complexity raises new difficulties for theories of justice. Is the equal opportunities theory the most appropriate to solve these difficulties? I demonstrate that epigenetics requires a multifactor model of justice—one that is grounded on principles of fairness, impartiality, and environmental and intergenerational justice. Depending on the point of view assumed (i.e., individual, population-based, or intergenerational), the relevant principle of justice is different.
