The 15th Gavin David Young Lecture in Philosophy will feature Professor Kim Sterelny from Australian National University exploring the topic, ‘Evolution and Moral Realism: Take 2’.

A decade ago I offered a defence of naturalistic moral realism against evolutionary debunking arguments. It had two elements. One was rejecting a dichotomy between evolutionary vindication and debunking in favour of a continuum. The second (a) proposed a metaethical principle on the basis of a hypothesis about the evolutionary drivers of moral thinking: a moral principle is true if it is part of a set of moral norms which, if acted upon, would optimise the cooperation profits of a community, and (b) by this criterion, folk moral opinion was quite often approximately true.

I still reject the dichotomy, but the rest of the argument was too friendly to realist naturalism in ethics. It mis-characterised the selective history of moral thinking, over-estimating its role as a cooperation amplifier, and under-estimating the epistemic challenges facing individual agents as they develop their moral opinions. The upshot is a shift towards the debunking end of the vindication-debunking continuum.
