Paul Goodman, "Five Years" (1966),
chapter 1959, section "ii method",
p. 203-4:
"Darwin says, 'This experience taught me
never to trust, in science, to the principle
of exclusion.' Because an unthought of
reason, of a different kind from the
exclusive alternatives, might prove to be
the case. This is a good weak-definition of
science: it is logic without the principle
of exclusion. As Aristotle puts it
positively, Science only demonstrates from
real, rather than dialectical, premises."
"More usefully, we can say: Logic is
science plus the principle of exclusion.
This formulation gives the essence of
'analytical propositions', with more
materiality than postulate sets, and
without their arbitrariness. Logic is the
structure of any bracketed-off 'finished'
system of inquiry."
Adding a paragraph
"It is only from a highly developed break of my own.
science, implicitly using much logical
machinery, that we can understand what An action easy
logic is. To conceive of 'logic' as such, to perform, but
is a delusion. But sciences we have from difficult to
the beginning, they are the human animal talk about,
itself. Naively, we do not in fact look particularly
for a 'critereon' of truth, but for what if you'd like to
amount of articulation, structure, and explain the
comprehensiveness suits a present need to reason and excuse
know." the liberty.
The Holmes principle is inadequate:
"Once you have excluded the impossible,
whatever remains, however improbable,
must be the truth."
If it's improbable enough, you would go
back over the process rather than just go
with it: you may have missed a possibility,
there could be other alternatives, perhaps
some that seem more probable once you've
recognized them.
