REVIEW OF "UNIFICATION AND EXPLANATION"
1) H&H: no unification is explanation, cause explanation involves acquiring
new beliefs, whereas unification consists in the systematization of old
beliefs.
2) H&H: Explanation is derivation of the explanandum from a background
theory and the auxiliary or contextual information.
3) H&H distinguishes between:
i) the construction of theories and the application of theries; it seems
that, they consider that the construction of theories is a less explanatory
activity.
ii) specified and unspecified
why-questions.
My considerations:
I consider that, philosophy of science should be live at the intersection
between intelligibility, rationality, economy, validity and science.
Philosophers should treat about the most intelligible scientific notions,
to promove a harmony between all special sciences, and increase the
compatibility between philosophy and science.
That is why, I dont like too much diverse, but I like to refine some
scientific articles. The more we fall in philosophical distinctions and
beliefs, the more we move off science. The more we fall in scientific
details, the more we remove of philosophy...and can no more master the
scientific diverse.
Now, I consider, from above, that, H&H' bacground theory is, from a
cognitive criterion, a special universality or generality (but only a
causal one).
Similarily, I consider that, the so called initial conditions or auxiliary
information are/is an information that mediates the subsumption and
connection between
the universality and explanandum.
That is, H&H'explanation is also subsumptory.
But the subsumption of many individual cases under a universality (either
causal or non-causal) is unificatory, clasificatory...
That the construction of a theory as a response to a why-question is less
explanatory, it seems to me too artificial, less important, less true, too
sofisticated.
We have both general explanations
and particular and individual explanations.
Deduction implies subsumption.
The intermediar information mediates a subsumption. Subsumption is
unificatory.
But, the universality, at least when the explanandum is about a natural
fact,
should be causaly reconstructed, I consider.
H&H:..."explanation thus involves acquiring new beliefs"...
Consider the following case:
