The law has taken a long-standing interest in the mind. Cognitive neuroscience, the study of the mind through the brain, has gained prominence in part as a result of the advent of functional neuroimaging as a widely used tool for psychological research. Existing legal principles make virtually no assumptions about the neural bases of criminal behavior, and as a result they can comfortably assimilate new neuroscience without much in the way of conceptual upheaval: new details, new sources of evidence, but nothing for which the law is fundamentally unprepared. Neuroscience challenges ultimately reshape our intuitive sense of justice. It draws a familiar distinction between the consequentialist justification for state punishment, according to which punishment is merely an instrument for promoting future social welfare, and the retributivist justification for punishment, according to which the principal aim of punishment is to give people what they deserve based on their past actions.

The passage in question begins with a breakdown in the discussion between Socrates and Protagoras because of disagreement about what its ground rules will be and concludes with the discussion’s restoration. Though formally a mere hiatus from the main line of argument, this passage in fact contains a parable about politics, addressing the question, "How can people of differing abilities and preferences come together to form a community?" Since the passage appears in the middle of a dialogue explicitly concerned with education, the parable extends to education as well. The passage thus provides a springboard for insight into some essential interconnections between and among philosophy, education, and politics. On the one hand, a genuine practitioner of any of the three is ipso facto a engaged in the other two at the same time. And on the other hand, the three share an internal structure which is reflexive and transitive at the same time.
