“We are evolved creatures. Our physical attributes, behavioural dispositions, and cognitive capacities have developed in reaction to and by using the environments in which our ancestors have reproduced more successfully than their competitors.”
This is (the sketch of) a scientific, causal explanation of why we are the way we are and do the things we do.
The practice of explaining things that way has evolved, too: It has been more successful in its (cultural, intellectual, economic) environment than competing practices. And it is connected with and built upon a host of other evolved practices: Logic, statistics, a certain way of doing natural science. All of these practices can be explained scientifically, extending the above sketch.
But by doing so, we are also using these practices.Accounts similar to the one developed here can e.g. be
found in Ismael (2007), Lance and Kukla (2010), and Rouse (2015), all of
which belong in the so-called Neopragmatist camp of philosophy.
While we account for them from a third-person
perspective, they shape our thinking and thus define our perspective
onto the world and, eo ipso, onto themselves: our
first-person perspective.
What is distinctive about our first-person perspective, more than any
form of consciousness, is its discursive structure. As evolved
animals, we are discursive creatures:Since other species’ first-person perspectives are
inaccessible to us, we have no way of validating this distinction fully,
but research into their linguistic capabilities shows these don’t match
the abstraction, creativity, and normativity available to humans. Even
if the concept of morality is particular to humans, though, this doesn’t
mean other animals’ perspectives are morally discountable.
We have been evolutionary successful due – among other
things – to our ability to use concepts and reason collaboratively.
This ability enables us to explain practices from the outside – but
also to articulate them from the inside, from within
the first-person perspective. A violin-maker, e.g., can spell out the
actions and rules involved in creating a violin, even if she can’t
explain why and how they work scientifically. And what’s more, she can
more effectively help someone learn to build a violin by
articulating the practice than by explaining it scientifically.This resonates with Michael Polanyi’s distinction
between explicit and tacit knowledge: while
explanation might be a powerful tool to convey the former, it is
unsuited to transmit the latter.
This is also how science itself is learned – by following the
practices other scientists are using and articulating. So are
philosophy, mathematics, architecture, software development. To learn
them is not about knowing something, but about knowing how
to do something.The relationship between these modes is controversial.
A major strand in philosophy and cognitive science views knowing
how as primary, arguing that propositional is derived from
practical knowledge or that “competence precedes comprehension”.
When practices evolve, they do so not only by natural and cultural
selection – they are also advanced by critique. Articulating,
questioning, and validating them helps make them fitter for their
environment. We can consciously change rules and actions, and test their
practicability and success; we don’t have to rely on random mutation.
This is what we call design.Daniel Dennett refers to this as “intelligent design”
and also contrasts it with (Darwinian) natural selection.
Practices, scientifically speaking, contain models they use
to make sense of the world. When articulating a practice, we describe
these models using a certain language, providing the theory of
the practice.The theory of a practice, in my use of the
expression, articulates what the practice itself and the model
at its core take the world (or the part of the world they deal with) to
be or to be for as it is relevant to the practice. This is not to be
confused with a theory that explains from outside the practice
why and how it works in terms of a different field of knowledge. For
example, the violin-maker’s theory of violin-making will articulate why
and how skilled actions will result in certain results (hopefully, a
great-sounding violin). In contrast to that, a sociological theory of
violin-making might explain why and how the skills involved were
discovered, passed on, and monetised; a physical theory might explain
why and how modifications of material result in a specific sound of the
finished violin.
Its form is partly shaped by the practices used in the
articulation.
The theories of our technically most advanced practices are articulated mathematically and thus shaped by the (perceived) current state of mathematics. This is why mathematical objects as different as Platonic solids and the so-called amplituhedron play similar roles in ancient and current physics’ endeavour to explain what the world “really is”, representing the current state of mathematics then and now. And it is how the intellectual edifice of modern economics could be built upon what is now seen as a misunderstanding of fundamental statistical concepts.
Theories of other practices will take different forms – they might focus on patterns described in a semi-formal language (architecture), frameworks and methods relying heavily on visualisation (collaborative sense-making), or decision procedures aiming for reflective equilibria (ethics). A theory is helpful for training and critique if it has a form that fits the practice and its practitioners’ goals and capacities.
The models at the core of our practices don’t represent the world in
a way that can be meaningfully evaluated as more or less
faithful – for this, we would need access to the world that is
unmediated by models. The theories describing the models aren’t selected
for their consistency and elegance, either – astrology, e.g.,
was in no way inferior to early astronomy in this respect.In fact, when originally conceived, astronomy and
astrology represented a unified way of looking at (astronomy) and
explaining (astrology) celestial bodies and their motions. Only with the
arrival of the Scientific Method and the demise of geocentrism, this
changed and both disciplines got separated. The ensuing
scientific success of astronomy was complemented much later by
the resurgence and (pop-)cultural success of astrology.
As parts of practices, models and theories are selected
for the success we achieve when using them instead of their
rivals. Their use increases with their usefulness.
The same goes for the criteria we use when selecting them – and thus for our understanding of rationality. We are “instrumentally rational” when our means fit our ends – when we successfully use our practices to achieve our goals. This is the scientific, third-person view of rationality. From a first-person perspective, rationality as a demand on practices can be articulated in different ways – e.g. as requiring coherence, conformity with (specific) reasons, or objectivity. Which description we prefer is a matter of evolutionary fitness – of whether a description is useful for advancing certain practices, and of whether it survives and reproduces in its intellectual environment, e.g. scientific publishing or academic philosophy.
The articulation of rationality can cover the internal structure of a particular practice, e.g. architecture or ethics, and thus describe its specific conception of rationality or “logic”. Or it can abstract away from particular practices and try to describe a general conception of rationality or a universal logic. The first is what the reflective practitioner does; the second is the philosopher’s job.
This is why doing meaningful philosophy is so hard: Articulating and
critiquing rationality in toto requires a high level of
abstraction as well as an acute sensibility for the border between
useful generalisation and complete dissociation from particular (and
particulars of) practices.As an example, from this perspective, Niklas Luhmann’s
rationalist systems theory is a hyper-reductionist and thus
overgeneralized articulation maladapted to describe, critique and
advance actual practices.
From all of this follows that the two perspectives are complementary. Without either, our understanding of the world and us in it is incomplete: First-person articulations that don’t correspond to third-person explanations are fantastical; third-person explanations that aren’t grounded in and bounded by first-person articulations are imperialist.
Only if we avoid both traps and instead respect both
perspectivesThis demand is similar to Wilfrid Sellars’s call for a
“fusion” of the “manifest” and the “scientific image of man in the
world”. (Sellars 1963)
do we find reason.
