  Already in Book Four, Glaucon is ready to declare that unjust souls  are ruined and in turmoil. But Socrates presses for a fuller  reckoning. When he finally resumes in Book Eight where he had left  off in Book Four, Socrates offers a long account of four defective  psychological types. The list is not exhaustive (544cd, cf.  445c), but it captures the four imperfect kinds of pure psychological constitutions: pure rule by spirited attitudes, pure rule by  necessary appetitive attitudes, pure rule by unnecessary but  regulable appetitive attitudes, and pure rule by lawless appetitive  attitudes. At the end of this long discussion, Socrates will again  ask which sort of person lives the best life: the aristocratic soul  of Books Six and Seven, or one of the other souls of Books Eight and  Nine?
