Much has been written about the seductive allure of fMRI brain images accompanying research papers and giving them more credence than is deserved; similarly much has been written about the whole enterprise of fMRI based research that tries to find the neural correlates of X,Y,and Z, as if X/Y or Z being human/animal faculties could have a substrate other than neural.
In both of the above cases, while the neuro babble seemingly provides more authority to the underlying argument, it is not clear what value , if any , one gets by just identifying a brain area responsible for X/Y or Z.
Patricia Churchland‘s quest for roots of human/animal morality is similarly besieged by the allure of all things neural- it is to her credit that despite being a philosopher she gets the neuroscience part not just so-so right, but precise and accurate with all caveats included; but what one is left at the end of reading ” Braintrust : what neuroscience tells us about morality” is the feeling that she could have spent more time bolstering her main point that morality arises from sociality rather than talking about oxytoctin or mirror neurons.
While she does treat mirror neuron hyped research with the contempt and dressing that it deserves by trying to explain more than is warranted; her own enthusiasm for Oxytocin as the magical trust molecule or the epitome of moral foundations, deserves similar treatment. Again it is to her credit that she does not shy away form discussing latest studies that have shown oxytocin in not so moral light as in when it is involved in out-group prejudice; but still the discussion of neurotransmitter or vasoprassin or mirror neurons detracts rather than amplifies her thesis that morality evolved from social living.
I am much sympathetic to her main argument that morality may have arrived as the care system became enlarged to cover self, kids, kith and kin, partners and finally strangers. That caring and sharing might be the roots of all goodness in the world was apparent even to miss universe like Sushmita Sen back in 1994, not an unremarkable achievement considering the latest miss America contestants views on evolution. But I digress. The thing is that Patricia should have spent more time on this and bridging the leap from social behavior to moral behavior by maybe using philosophical devices/arguments rather than just peppering her statements with neuroscientific jargon and assuming that that will settle the point.
Along the way she casually dismisses the important work that may support her position like that of Jonathon Haidt- she claims that morality is innate but seems reluctant to grant that it could also have a universal structure.
If you want to know the latest neuro research around sociality – go read this book; you will read all the proper studies with all caveats and without misrepresentations. However, if you were yearning for any philosophical insight into the nature of morality, how ‘is’ and ought’ are not necessarily the same and from where to derive the ‘oughts’ in life you might be in for a disappointment. At least I was.
