Tim Whitmarsh in The Guardian:
In his view, people everywhere grapple with the same moral questions, which are fundamentally about balancing contradictory imperatives: individual autonomy versus collective good; the social need for impartial arbiters of truth versus awareness of subjective experience; adherence to rules versus commonsense flexibility; and so forth. The differences between people lie not in the issues they face, but in the positions they end up adopting on the scale between the extremes. The analogy he draws is with a producer in a recording studio: “By sliding controls up or down, the volume of each track can be increased or decreased.” All cultures play the same song, but some prefer the cymbals higher up in the mix.
