Recent work has stressed the importance of the concept of solidarity to bioethics and social philosophy generally. But can and should it feature in documents such as the Universal Declaration on Bioethics and Human Rights as anything more than a vague notion with multiple possible interpretations? Although noting the tension between universality and particularity that such documents have to deal with, and also noting that solidarity has a political content, the paper explores the suggestion that solidarity should feature more centrally (...) in international regulations. The paper concludes with the view that when solidarity is seen aright, the UDBHR is an implicitly solidaristic document. (shrink)
