Science : Known and usually recorded
facts and experimentally testable
rational
explanations thereof. This also covers
mathematics in so far as the theorems
of mathematics concern mathematical facts,
if only about the properties of certain kinds of imaginary
structures. The explanations of mathematics
are its proofs (and eventual explanations
thereof). The reason to insist that these facts
and their explanations be recorded (if only memorized) is that if they
are not they can hardly be shared and made the subject of critical
investigation and testing: Science is a fundamentally public
affair, conducted by a public of
likeminded informed persons. And
science, or scientific knowledge, is special and important
in that it is the only kind of human belief that is based on the desire
to find the truth about parts or all of reality by logical reasoning and
experimental testing of hypotheses.
