True. Though sometimes what we
thought were facts turn out not to be.
There is another complication in the case of the "facts" involved with evolution. There is a classic confusion that is often made between the
facts of evolution as observed, for instance, in populations of bacteria that become drug-resistant, or the famous "peppered moth", and the
theory of evolution of species by natural selection, for which there is vast evidence, but is not a "fact" any more than any other theory can be a fact.
The theory of evolution has undergone quite a bit of change in my lifetime, e.g. punctuated equilibrium and epigenetics. So I think to be fair to our poster he or she may be thinking of this. (Though the inclusion of a Berlinski video may on the contrary signify an IDer running up the Jolly Roger.
We'll see.)
I am going to be a bit fussy here, on the subject of facts.
This is the only use of the word in science that I
understand to be correct.
"It is a fact that this is my data".
Or more collectively, "it is a fact that nobody
has disproved ToE" (or the gas laws)
Now, there can be problems with the data, there
can be more in the interpretation of the data.
I suppose in that narrow sense, one could say that
what is a fact today might not be tomorrow.
Some guy was champion today, is not tomorrow.
That kind of thing.
Of course, our friend was not getting into nuance,
but saying evolution was a fact and then it wasnt.
Refinements in a field so vast as inquiry
into matters related to To,E will be taking place
continually.
But to return to changeable facts.
I will go with my misquote of Feymnman on
this- something to the effect of how
"this is how things now seem to me to be"
Dont figure on anything in science being a fact.
