Lifespan extension and the doctrine of double effect

Recent developments in biogerontology—the study of the biology of ageing—suggest that it may eventually be possible to intervene in the human ageing process. This, in turn, offers the prospect of significantly postponing the onset of age-related diseases. The biogerontological project, however, has met with strong resistance, especially by deontologists. They consider the act of intervening in the ageing process impermissible on the grounds that it would (most probably) bring about an extended maximum lifespan—a state of affairs that they deem intrinsically bad. In a bid to convince their deontological opponents of the permissibility of this act, proponents of biogerontology invoke an argument which is grounded in the doctrine of double effect. Surprisingly, their argument, which we refer to as the ‘double effect argument’, has gone unnoticed. This article exposes and critically evaluates this ‘double effect argument’. To this end, we first review a series of excerpts from the ethical debate on biogerontology in order to substantiate the presence of double effect reasoning. Next, we attempt to determine the role that the ‘double effect argument’ is meant to fulfil within this debate. Finally, we assess whether the act of intervening in ageing actually can be justified using double effect reasoning

Epistemic pluralism, epistemic relativism and ‘hinge’ epistemology

According to Paul Boghossian (2006, 73) a core tenet of epistemic relativism is what he calls epistemic pluralism, according to which (i) ‘there are many fundamentally different, genuinely alternative epistemic systems’, but (ii) ‘no facts by virtue of which one of these systems is more correct than any of the others’. Embracing the former claim is more or less uncontroversial–viz., a descriptive fact about epistemic diversity. The latter claim by contrast is very controversial. Interestingly, the Wittgenstenian ‘hinge’ epistemologist, in virtue of maintaining that rational evaluation is essentially local, will (arguably, at least) be committed to the more controversial leg of the epistemic pluralist thesis, simply in virtue of countenancing the descriptive leg. This paper does three central things. First, it is shown that this ‘relativistic’ reading of Wittgenstein’s epistemology is plausible only if the locality of rational evaluation (in conjunction with a reasonable appreciation of epistemic diversity) commits the Wittgenstenian to a further epistemic incommensurability thesis. Next, Duncan Pritchard’s (e.g., 2009; 2015) novel attempt to save the hinge epistemologist from a commitment to epistemic incommensurability is canvassed and critiqued. Finally, it is suggested how, regardless of whether Pritchard’s strategy is successful, there might be another very different way—drawing from recent work by John MacFarlane (2014)—for the hinge epistemologist to embrace epistemic pluralism while steering clear of epistemic relativism, understood in a very specific way
