Abstract

Clive Staples Lewis, a philosopher, believed that our thought is inherently about things. Because it is, we are able to construct derivative forms of aboutness that represent things. Lewis considered a characteristic in his treatment of the philosophical theory that is called as “naturalism”. Lewis believed that a view like naturalism, which implies that a mental phenomenon like reasoning must and will ultimately be entirely explicable in nonmental and non‐psychological terms, “is really a theory that there is no reasoning”. Lewis wrote in the margin of his edition of Aristotle's Ethica Nicomachea that “the 'parts of the soul' are only a metaphor”. He was convinced that a belief in dualism is essentially an ordinary belief in a distinction between a soul and its body. Beliefs about the natures of the body and the soul have to await philosophical reflection. Common sense itself is philosophically idle.
