In the search for what might be the "reasonable
part" of so called inductive processes, one can declare that
there are forms in the way that there are forms of deductive
arguments or one might simply note that not all deductive
arguments have a form but are simply such that one cannot
reasonably assert the premises and deny the conclusion and be
reasonable in doing so. Either way, the problem of induction is
to identify *any general circumstances* that can be described in
which one can assert a set of premises and conclude something
where it would always be unreasonable to deny that at least the
premises give the conclusion some weight of probability.
