The single principle is that there is really no such thing as
"science"! Science is merely systematized, institutionalized common
sense. The infant (human or other animal) learns from trial and
error experience what to eat, avoid, mate with, etc. That learning
from trial and error experience is already "science". Doomed is the
forager who is not a "scientist" -- who does not learn to avoid the
grains that have made him sick in the past, favour the terrains
that have been plentiful, crack the nut before sinking his teeth
into it. Doomed too is the organism that is indifferent to the
outcome of his experiments: the one that keeps sticking his nose
back into the fire. We humans have a second way of doing science,
over and above individual trial-and-error (experimental) learning,
guided by the error-correcting feedback arising from the consequences
of our actions: We also have language, and can save one another
a lot of risky and time-consuming experimentation by telling one
another what's what. We can of course lie, or be in error. So our
statements can be true or false. But the true ones ("Don't eat the
mushrooms with the stripes: they will make you sick" or "Find a rock
and smash the nut and you will find something good to eat inside")
are our second way of doing science: By describing the outcomes of
our experiments, and sharing them with others.
