Currently, the self has replaced the soul as the major focus of much p
sychological theorizing. I argue that this shift is due to a number of
confusions regarding the nature and justification of substance dualis
m. I also claim that this focus on the self, without a framework that
treats it as a substantial soul, leads to a number of conceptual probl
ems and terminological equivocations. Moreover, I show that certain fe
atures of widely accepted views of the self actually seem to require a
substantial soul to make sense. To substantiate these claims, Section
I contains a discussion of a set of current misunderstandings about t
he nature of a substance (e.g., that a substance is a static thing unr
elated to other things), and a treatment of key problems with current
models of the self (e.g., that the self is a construct of language). S
ection II compares two very different views of wholes with parts-subst
ances vs. property-things. Section III clarifies the essence of substa
nce dualism by describing five states of the soul and the nature of a
faculty of the soul. The section closes with a sketch of the main type
s of considerations that justify belief in substance dualism. In the f
inal section, I argue that the self is the soul by showing how key fea
tures of certain psychological models of the self seem to require subs
tance dualism to make sense and by clarifying a set of psychological t
erms/concepts in light of what has been argued earlier.
