Inductive inference is one kind of
deductive inference:
a deductive inference from properties we know
finite.ordinals have because they are finite.ordinals.
⎛ What Mathematics calls "induction" is deduction.
⎜ What Physics calls "induction", for example,
⎜ our conclusion that the sun will rise tomorrow
⎜ because we know of many yesterdays it rose,
⎝ is a different kettle of fish.
The super-task or Thomson's Lamp has helped
to establish the infinitary as within reason.
If
⎛ making finite.length claims which
⎜ we know are true of infinitely.many
⎜ by making a claim about an indefinite one
⎝ which we know has no exceptions
is something you (RF) consider a supertask,
then
we -- although finite -- perform super.tasksᴿꟳ,
because (making...) is something we do.
I prefer not to consider that a super.task,
primarily because we are finite, which
seems to contradict our performing super.tasks.
However, my point is that we
⎛ make claims we know are true of infinitely.many
⎜ by making a claim about an indefinite one
⎝ which we know has no exceptions,
and therefore,
however things stand with supertasks,
we can, by (making...), learn about infinitely.many.
