conditions of consistency; but the smaller Logic ought to be (at
least, finally) studied as part of the greater--as a portion of the
means to the same end; and its relation to the other parts--to the
other means--should be distinctly displayed."]
After adverting to another variety of ratiocinative procedure, which
he calls _Apagoge_ or Abduction (where the minor is hardly more
evident than the conclusion, and might sometimes conveniently become
a conclusion first to be proved),[75] Aristotle goes on to treat of
Objection generally--the function of the dialectical respondent. The
_Enstasis_ or Objection is a proposition opposed not to a conclusion,
but to the proposition set up by the defendant. When the proposition
set up by him is universal, as it must be if he seeks to establish an
universal conclusion, your objection may be either universal or
particular: you may deny either the whole of his proposition, or only
one portion of the particulars contained under it; the denial of one
single particular, when substantiated, being enough to overthrow his
universal. Accordingly, your objection, being thus variously opposed
to the proposition, will lie in the syllogistic figures which admit
opposite conclusions; that is, either in the First or Third; for the
Second figure admits only negative conclusions not opposed to each
other. If the defendant has set up an Universal Affirmative, you may
deny the whole and establish a contrary negative, in the First
figure; or you may deny a part only, and establish a contradictory
negative, in the Third figure. The like, if he has set up an
Universal Negative: you may impugn it either by an universal contrary
affirmative, in the First figure; or by a particular contradictory
affirmative, in the Third figure.[76]

In objecting to A _universally_, you take a term comprehending the
original subject; in objecting _particularly_, a term comprehended by
it. Of the new term in each case you deny the original predicate, and
have thus, as a major premiss, E. For a minor premiss, you affirm, in
the first case, the new term as predicate of the original subject
(less comprehensive); in the second case, the original subject (more
comprehensive) as predicate of the new term. This gives you, in the
first case, a conclusion in _Celarent_ (Fig. I.), and, in the second,
a conclusion in _Felapton_ (Fig. III.); opposed, the one universally
or contrarily, the other particularly or contradictorily, to the
original proposition.]
