Scheme-content
dualism, coherentism and John McDowell’s third
position
In his much-discussed book Mind and
World, John McDowell portrays two positions that we are in danger of moving
back and forth between, each one being unsatisfactory. One of these positions
is the dualism of scheme and content. The other position is coherentism.
The advocates of each position have an objection to the other. Neither party
can adequately answer the objection put to them. This leads McDowell to propose
a third position. Below I present the debate between the scheme-content
dualist and the coherentist and then McDowell’s
response.
Scheme-content
dualism
The dualism of scheme and
content, as McDowell understands it, is a philosophical picture that involves
the following commitments: (i) it is possible for
there to be justified conceptual representations of the world; (ii) a given
conceptual representation is justified, if at all, by sensory experience; (iii)
a sensory experience is not a conceptual representation of the world.
The coherentist
objects to scheme-content dualism by asserting that it is unintelligible how
something that is not a conceptual representation could play a justificatory
role.
Coherentism
The kind of coherentism that McDowell focuses on involves the following
commitments: (i) it is possible for there to be
justified conceptual representations of the world; (ii) a given conceptual
representation is justified, if at all, by other conceptual representations;
(iii) a sensory experience is not a conceptual representation of the world.
Donald Davidson is
McDowell’s example of a coherentist. Davidson says
that only a belief can justify another belief. He seeks to counter the
objection that our beliefs could be entirely coherent yet entirely false.
McDowell describes this as a shallow scepticism. He regards the scheme-content
dualist as making a deeper objection: that unless sensory experiences have a
justificatory role, there cannot be conceptual representations of the world at
all.
McDowell’s
third position
McDowell agrees with the
objections put forward by both parties. The deadlock in the debate motivates a
third position. To form his third position, McDowell denies a commitment common
to the coherentist and the scheme-content dualist:
that a sensory experience is not a conceptual representation of the world. He
thinks of sensory experiences in mature human beings as conceptual
representations, though not beliefs. In experience, I take in that the world is
certain way – that a wall before me is green, for example. These takings-in can
justify. For example, if I take in that the wall is green, through visual
experience, then, under normal circumstances, I am justified in believing this.
For experience to justify in this way, it must be a conceptual representation.
Removing
obstacles
McDowell thinks that,
since the scheme-content dualist and the coherentist
cannot answer each other’s objections, we have reason to accept his third
position. But he recognizes that there are obstacles to embracing it, in
particular claims that might, understandably, lead us to reject his conception
of sensory experience. McDowell aims to remove these obstacles. I will
present only one of the obstacles he considers.
This is the claim that it
is impossible to articulate exactly what I experience. The concept of green
does not accurately capture the exact shade of green that I saw, so how can a
sensory experience be a conceptual representation? McDowell denies the impossibility
claim by saying that demonstratives, such as ‘that’, mean that it is possible
to articulate the exact shade that I saw. I can point to a colour sample and
say, ‘It was that shade of green.’

scheme and content’. See here.)
