What do we mean when we talk about epigenetic harm? This paper presents a multidimensional view of epigenetic harm. It is a plea to take a step back from discussions of epigenetic responsibility distributions prevalent in ELSA literature on epigenetics. Instead, it urges researchers to take a closer look at the normative role played by the concept of epigenetic harm. It starts out by showing that the ways in which the object of epigenetic responsibility has already been conceptualized are all (...) related to ‘epigenetic harm’: something negative that happens in which epigenetic mechanisms play a role, or rather something that needs to be avoided. Epigenetic harm is then characterized as a bridging concept between relatively neutral findings on epigenetics on the one side, and potential ethical and societal implications of those findings, primarily in terms of responsibility ascriptions and distributions, on the other. The paper proposes that a sufficiently nuanced account of epigenetic harm should include at least three dimensions. The dimension of causation alone leads to an overly narrow understanding of harm, and a wrong understanding of this dimension might prompt researchers to support an excessively simplistic epigenetic determinism. It is argued that a multidimensional analysis of epigenetic harm is less vulnerable to this threat and more reflective of the various kinds of harm that may be experienced by the subjects of epigenetic alterations. The paper applies insights from disability studies and feminist philosophy to draw attention to two other dimensions of epigenetic harm, namely lived experiences and relationality. The paper concludes by exploring what a shift towards a multidimensional approach to epigenetic harm might mean for epigenetic research and responsibility ascriptions by formulating some concrete implications.
