12. Knowledge
Here I start a series on knowledge, learning and
invention.
I adopt the constructivist view
that we perceive, interpret and evaluate the world according to mental
frameworks that in turn develop from interaction with the world. As a result,
our ideas guide our actions but also develop from it.
Philosophically, this is related to pragmatism
(going back to the ideas of e.g. John Dewey). Primarily, this is an attitude
against dogma, a mentality of openness to surprise, plurality and change of
ideas. It sees the knowing subject not as an autonomous, outside spectator
taking an objective view of world, but as involved in it. Subject and object
cannot be separated. We do not have objective knowledge of the world as it is
beyond our ideas. Ideas are always preliminary and fallible, and adapt in the
face of obstacles, misfits and novel opportunities.
That, I think, is also how entrepreneurs operate.
These views stand in contrast with, among other things, economic theory
with its assumption that actions are based on prior, given knowledge and
preferences.
This is important especially in innovation, where there is radical uncertainty: what may happen and
what one may choose from are largely unknown prior to choice and arise from
action after a choice is made. This yields a fundamental problem for the idea
of rational choice to which economics is committed.
Another consequence is that since people develop their ideas along different
paths of life, their ideas will differ to the extent that they developed in
different circumstances. In other words, there is greater or lesser cognitive distance between them. I will
discuss that notion in more detail later.
Now, if we cannot claim to know reality objectively, does the notion of
reality still make sense? I think it does, a follows. Although we cannot know
reality as it is in itself, it is reasonable to assume that there is a reality
and that we develop our ideas from interaction with it. In that sense reality
has a causal influence on our ideas, and our ideas ‘have something to do’ with
reality. If in evolution the development of our ideas had not been adequate
enough to the world for us to survive we would not be here.
The fact that different people view the world differently does not imply
relativism in the sense that any idea is as good as any other and rational
debate is impossible. On the contrary, precisely because we have no rock-bottom
objective knowledge, the only chance we have for correcting our mistakes is
debate with people who have learned to see the world differently.
We cannot achieve truth in the old sense of some correspondence between basic ideas with items in reality, from
which we construct knowledge. As a result, facts become problematic. They are
always constructed. However, in debates between competing theoretical
perspectives, one can often reasonably agree on what facts to accept, since the
facts are more stable and reliable than theoretical speculation, even if they
are not rock-bottom objective.
This yields the notion of truth as warranted
assertability, which is a coherence
theory of truth. We argue on the basis of everything we can muster that may
be relevant: whatever facts we can agree on, even if only temporarily, alternative
views and explanations, arguments of relevance, arguments of logic, and
arguments of efficiency in reasoning. This yields no guarantee of agreement.
There will remain rival views. But debate helps to reduce disagreement and to
raise doubt.
