Bruno, those 'idealistic' definitions from Leibnitz and Descartes are not
experienced in -
- what is called usually as "science". Look at the "Laws" of physics, does
engineering doubt them? The statements of 'logic', arithmetic, etc. etc. are
all " believed" as FIRM laws. Now that is what I call 'reductionist" = to
consider a topical limited cut from the totality for the relevant (?)
observations WITHIN such (what I call: model), and draw conclusions if there
were nothing else to consider. That is what Academia (tenure-Nobel) does and
what - as I wrote - most editing companies accept for publication. This is
close to what young minds get brainwashed into in college education. e.g.
Physics 101 etc. (Neurology not exempted).
Absolutely different from what you and I said. No 'flexible mind' allowed.
I hope you accept "my terms" for 'reductionist science' <G>,

Thanks for telling. I thought, a bit naively perhaps, that after
Descartes and Popper, say, it was part of common knowledge that
science, properly understood, is an arrow from doubts to ... more and
more doubts, and cannot, thus, be reductionist.
You know, people like Leibniz and even the young Hilbert thought that a
machine could exist capable of answering, at least in principle, all
question about numbers, actually all question about machine as well,
including herself. Now we know that we can interview machine as
powerful as we want, as far as they remain self-referentially correct,
they remain extraordinarily modest. If you ask to such a machine if she
will ever say a bullshit, well, the young one crash immediately
(transforming herself into a universal dovetailer btw), the older one
answer that either they will say a bullshit, or that they ... might
say a bullshit(*).
(*) For the modalist: "I will prove a falsity or it is consistent that
I will prove a falsity"
Bf v DBf (same as Dt -> ~BDt).
With the older modal notation:
f v <>f (same as <>t -> ~<>t )
B =  = Godel purely arithmetical provability predicate (Beweisbar)
D = <> = ~B~= ~~
Recall that, as Aristotle already got, ~B = D~ and ~D = B~ (in the
alethic mode: not necessary p = possible not p ; not possible p =
necessary not p. See my older modal posts.
