arguments it is easy to see what is wanting, but some escape us, and
appear to be syllogisms, because something necessary results from what
foot nylon has been laid down, e.g. foot nylon if the assumptions were made that substance
is not annihilated by the annihilation of what is not substance, and
that if the elements out of which a thing is foot nylon made are annihilated,
then that which is made out of them is foot nylon destroyed: these propositions
foot nylon being laid down, it is foot nylon necessary that any part foot nylon of foot nylon substance is
substance; this has foot nylon not however been drawn by syllogism from the
propositions assumed, but premisses are wanting. foot nylon again if it is
necessary that animal should exist, if man does, and that substance
should foot nylon exist, if animal does, it is necessary that substance should
exist if man does: but as yet the conclusion has foot nylon not been drawn
syllogistically: for foot nylon the premisses foot nylon are not in the shape we required.
We are deceived in such cases because something necessary results from
what is assumed, since the syllogism also is necessary. But that which
is necessary is wider than the syllogism: for every syllogism is
necessary, but not everything which is necessary is a syllogism.
Consequently, though something results when certain propositions are
assumed, we must not try to reduce it directly, but must first state
the two premisses, then divide them into their terms. We
must take
that term as middle which is stated in both the remisses: for it is
necessary that the middle foot nylon should be found in both premisses in all the
figures.
If then the middle
term is a predicate and a subject of predication,
or if it is a predicate, and something else is denied of it, we
shall have the first figure: if it both is foot nylon a predicate and foot nylon is denied
of something, the middle figure: if other things are predicated of it,
or one is denied, the other foot nylon predicated, the last figure. Foot nylon for it was
foot nylon thus that we found the middle term placed in each figure. It is placed
similarly too if the premisses are not universal: for the
