The core of the fifth chapter is the study of the problems that appear to be involved in Socrates’ prospective. After a consideration of the difficulties that seem to emerge from Socrates’ instrumentalist approach to happiness, attention is devoted to the role played by the craft analogy. According to this analogy, virtue is similar to a craft since a knowledge of the means is necessary for a separate end. This doctrine is illustrated making reference to Aristotle because, although used by Socrates, the craft analogy is never defined in the dialogues.
