Abstract
It is well known that in the Republic, Socrates presents a view of the soul
or the psyche according to which it has three distinct parts or aspects,
which he calls the reasoning, spirited, and appetitive parts. Socrates’
clearest characterization of these parts of the soul occurs in Republic
IX, where he suggests that they should be understood in terms of the
various goals or ends that give rise to the particular desires that motivate
our actions. In Republic X, however, Socrates uses the phenomenon of
cognitive conflict about matters of fact to show that the soul has only two
parts, the rational and the irrational. Moreover, he characterizes these
parts in terms of cognitive tendencies, such as forming beliefs on the basis
of reason versus forming beliefs on the basis of perceptual appearances.
In this chapter, I explain how these divergent accounts of the soul and its
parts are legitimate alternative characterizations. A consequence of my
argument is that we should not think of the divided soul as primarily a
division of desires, but rather as a division of cognitive attitudes towards
the world, each of which yields different sorts of desires.
