Truth is the aim of
inquiry, but what kind of truth is “scientific truth” is matter of debate.
First of all: does scientific inquiry really aim at truth? Instrumentalists and
anti-realists of various stripes would deny this. Even admitting that truth is
the goal of scientific inquiry, are scientific theories and hypotheses “true”
or “false” in the same way ordinary propositions are? What are the relations
between “ordinary” truth and “scientific” truth, or between the “manifest
image” and the “scientific image”? Other questions concern the nature of
scientific truth: should we construe it as correspondence to facts, as realists
do? Or is it better understood in a pragmatic and/or epistemic way, for
instance as the ideal limit of inquiry or as ideal rational acceptability? Or,
maybe, a deflationary approach to truth would be more appropriate? Moreover, it seems clear that, even if truth is
one cognitive goal of inquiry, there are others as well: to mention but a few,
accuracy, approximate truth, empirical adequacy, high probability, confirmation,
truthlikeness or verisimilitude, knowledge, understanding, and so on. What are
the relations between truth and these other “cognitive values” or “theoretical
virtues”? Is there a unique set of values guiding all kinds of scientific
activity, at all different levels (experimental, observational, theoretical,
and so on)? Or different goals characterize different levels? |
