EPISTEMOLOGICAL: On why scientists need a course in the history of
science
One
thing that Karl Marx got right was his concept of the sociology of
knowledge. Our thinking is largely affected, for better or for
worse, by our social environment. If that is so, then even the
theories of science are products of their time, that is, they are not
as objective as scientists suppose.
Examples
abound. Charles Darwin wrote The
Origin of the Species
during the heyday of the Industrial Revolution. Consequently, his
evolution theory, the process by which one species evolve into
another according to the Darwinian mechanism of variation and
selection, is highly mechanical. That is exactly what one might
expect from a 19th
century scientist working in the country wherein the Industrial
Revolution began.
This
is not to say that Darwin was wrong. Perhaps his theory was correct,
but was dependent on the advent of industrial thinking. If so, that
serves to explain why no one in the feudal age thought of it.
There
are related examples of the effect of the Industrial Revolution in
other academic disciplines. In psychology, think of how mechanistic
is Behaviorism, emerging as it did from the time when America joined
the industrial age. Behaviorism's simplistic stimulus--->response
explanation for human behavior, is altogether mechanistic. Also, to
a degree that even most psychologists seem unaware, Freudian
psychology, developed also during the period of heavy industry, is
also mechanistic.
I
repeat, the fact that the environment affects the development of
scientific theories does not necessarily mean that those theories are
wrong. However, and this is the important point, scientists should
be aware of the concept of the sociology of knowledge and therefore,
when evaluating any major thesis, they must consider the effect of
the social environment in which it was developed.
Not
to mention, of course, that if they are evaluating a theory of their
own time period, both the theory and their evaluation may be strongly
affected by the same social environment.
Furthermore,
when evaluating a theory postulated in the distant past, they must
take into account the social environment that influenced the
theorist, and they must be aware of the social environment that is
influencing their own evaluation.
Science
is not immune from external forces. Knowing the history of science
would help scientists to think objectively and/or to at least be
cognizant of biases of which they are often no more than dimly aware,
at best.
