Given this history, recent work being done in areas like epigenetics suggests that our political theories need to be updated even more substantially to reflect these more recent modifications of our understanding of the connections between each other and our environments.
This brief sketch of the fundamental challenges epigenetics poses to two of the most dominant ethical frameworks of modern liberalism is a good indication of the scope of the implications of epigenetics for modern liberalism in general, not only for the ethics, but also the politics and the jurisprudence of contemporary liberalism built on these same principles.
This new knowledge emerging from epigenetics not only introduces significant challenges to conventional understandings of gene-environment interactions, but also exacerbates many of the longstanding and unresolved fractures in modern liberal ethics.
Does epigenetics challenge contemporary political ideologies? This small study may serve as a starting point for broader studies of epigenetics as it comes to affect political ideologies and, in turn, public policies. The narrative mix reported here could yet prove vulnerable to ideological capture, or, more optimistically, could portend the emergence of a "third-way" narrative using epigenetics to question atomistic individualism and allowing for less divisiveness in public-health domains such as obesity.
The gene-centric focus of molecular genetics is usually portrayed as the product of the inevitable and impartial progress of science, but the material effects of the Second World War and its aftermath on the particular trajectory of the science of genetics are rarely considered.
The politicization of biology in the West before and during the Cold War was to play a significant role in the development of the science of genetics in the West over the subsequent fifty years, particularly in the prejudice against epigenetics—which also helps to explain the recent and seemingly sudden (re)emergence of epigenetics within the last decade or so.
The Progressive movement aimed at a fundamental reordering of the political system, while at the same time advocating for a reordering of society. Not surprisingly, these political changes also coincided fundamental changes in the prevailing understanding of biology.
The history of eugenics in early 20th century science must be addressed because of the sheer magnitude of its influence in the science and the politics of this era, its relation to the science of genetics that was to come, and because it provides such a strong example of the guiding model of this book of the inextricable connections between ideology, politics, and biology.
While 16,000 views over three years are clearly not Kardashian numbers, it exceeds my expectations by literally 8888% (I did the math). So I want to thank everyone who has visited the Nexus of Epigenetics and who will visit in the future. Stay tuned for my forthcoming book, Epigenetics and Public Policy: The Tangled Web of Science and Politics, to be released January of 2018. If you like the blog, you are going to LOVE the book.
The convergence of political ideology and biology in the work of Waddington helps to explain the development of his conception of the epigenotype, and of epigenetics as the scientific study of this epigenotype. Likewise, this convergence of biology and ideology is equally pertinent for understanding the development of the science of genetics as we now know it, which until the last decade or so more or less excluded epigenetics from serious consideration.
