In this chapter Ryle seeks to convince us that there is no
Ghost in the Machine. The intuition that there is some mental ‘inner’ precursor
to external actions is wrong. “…When we describe people as exercising qualities
of mind, we are not referring to occult episodes which their overt acts and
utterances are effects; we are referring to those overt acts and utterances
themselves” (Ryle 2000, p26).
Ryle seeks to move us from thinking about an inner mental
life, some of which leads to or initiates external behaviour. Instead,
the view (as I understand it) that he wants us to develop is that our mental
life is either expressed in a way observable to an external observer, or in a
way that is not. When we talk we are vocalising our thoughts, and when we
merely think (in words at any rate) we are doing the same activity a talking
but not vocalising it. The introduction of the Category Mistake in the previous
chapter was intended to prepare us for this move. Ryle gave an example of the
visitor to Oxford University seeing the colleges and libraries, but wondering
where the university is. Public thought (e.g. talking to someone) and private
thought (e.g. talking to yourself without vocalising) are like the colleges and
libraries, and the mind is the university.
Knowing How and Knowing That
Ryle draws a distinction between knowing how and knowing that. This distinction appears to map onto declarative and
procedural knowledge.
Misunderstandings and Feints
“Misunderstanding is a by-product of knowing how. Only a person who is at least a
partial master of the Russian tongue can make the wrong sense of a Russian
expression” (Ryle 2000, p58). Feinting also requires knowing how. It is the “art of exploiting”, or
provoking, your opponent’s premature conclusion of what course of action you
are following (Ibid.).
