 This is a remarkable difference, which changes the terms of the problem. Technical skills can help with natural necessities, but are not useful with human relations, which is by far a much more complicated problem. The emphasis on technai turns out to be excessive. What warrant human prosperity is the enactment of norms and laws (the problem of dike, justice), along with ethical and moral values (aidos, shame). These ideas are only sketched in the myth, but will be extensively developed in the second part of his speech, where Protagoras repeatedly underlines the political nature of human beings (see Protagoras 323a, 323b–c, 324c–325a). Protagoras’ myth, by underlining this point, presents a very subtle attack against technai and forcefully defends the importance of political art, which is the object of his teaching.
