One should be careful to distinguish between mathematical induction
and induction used otherwise(as in Physical sciences, ...)
Mathematical induction is logically derivable, atleast in concept, in
that it is essentially applying deduction infinitely.
Abduction may be logically invalid, but under the closed world assumption
it is empirically valid.
