Hardly a day passes without yet another breathless declaration in the popular press about the relevance of neuroscientific findings to everyday life. The articles are usually accompanied by a picture of a brain scan in pixel-busting Technicolor and are frequently connected to references to new disciplines with the prefix “neuro-“. Neuro-jurisprudence, neuro-economics, neuro-aesthetics, neuro-theology are encroaching on what was previously the preserve of the humanities. Even philosophers – who should know better, being trained one hopes, in scepticism – have entered the field with the discipline of “Exp-phi” or experimental philosophy. Starry-eyed sages have embraced “neuro-ethics”, in which ethical principles are examined by using brain scans to determine people’s moral intuitions when they are asked to deliberate on the classic dilemmas. Benjamin Libet’s experiments on decisions to act and the work on mirror neurons (observed directly in monkeys but only inferred, and still contested, in humans) have been ludicrously over-interpreted to demonstrate respectively that our brains call the shots (and we do not have free will) and to point to a neural basis for empathy.
