Perhaps they are not descriptions of how the world is, but attempts to
trigger a change in what we see the world as. If that is the case, however, then
the claim that doing philosophy historically teaches us about the nature of
reality falls flat. If Dupré’s claims are metaphysical propositions, then they
are inadequately supported by evidence. If they are not, then they cannot do
the job Dupré wants them to do.
Dupré’s strategy, then, seems problematic. What other approach could
we use? Perhaps we could ground the historical thesis not in a piece of
speculative metaphysics, but in an account of human nature. Perhaps there
are aspects of human nature that force us to do philosophy historically.
Perhaps some side of our being is such that, if we wish to do philosophy at
all, we must also study the development of philosophical pictures. Charles
Taylor advances a view of this sort. As we have seen, Taylor argues that
“[p]hilosophy and the history of philosophy are one,” and that we “cannot
do the first without also doing the second.”
31
Importantly, he understands
the historical thesis much as I do. For Taylor, to say that we must study the
history of philosophy is to say that we must reflect on the pictures or
conceptual frameworks we use to make sense of reality, and that we must
do so by tracing their development through time.
32
The reason we must do
so is that it is the only way of remedying certain defects in human nature. In
Taylor’s view, the side of human nature that forces us to do philosophy
historically is a specific type of forgetfulness. We tend to organize experience
by means of pictures or conceptual frameworks: sets of assumptions about
what the world is like and how we fit into it. For example, since the heyday
of early modern philosophy, Westerners have tended to filter reality
through a framework that Taylor calls the “epistemological model.”
33
This
framework assumes that “our awareness of the world … is to be understood
in terms of our forming representations – be they ideas in the mind, states of
the brain, sentences we accept, or whatever – of ‘external’ reality.”
34
The
epistemological model has well-documented problems, and, over the last
two centuries, philosophers of many different stripes have tried to criticize
or reject it. But it is hard to make people see its problems, because it has
become so deeply rooted in our thought that we see it as the unquestioned
truth about things, rather than as one possible model among many.
According to Taylor, reflecting critically on such models is one of the
main tasks of philosophy. Philosophy “essentially involves, among other
