Since 2001 the philosopher-neuroscientist Joshua Greene has developed a cognitive model of moral judgment in the context of the so-called «dual-processing accounts of human behavior», a family of theories that have in common the distinction between cognitive processes that are fast, automatic, and unconscious and those that are slow, deliberative, and conscious. In §1, I will introduce Greene's model, together with some experimental evidence that he offers in support of it; then, in §2, I will examine experimental findings that challenge the model; finally, in §3, I will reject the antagonistic view of emotions underlying Greene's cognitive theory of moral judgment.
