Such are the four Moods of the Dilemma that emerge if we only use affirmative hypotheticals for the major premise; but, certainly, it is often quite as natural to employ two negative hypotheticals (indeed, one might be affirmative and the other negative; but waive that); and then four more moods emerge, all having negative conclusions. It is needless to intimidate the reader by drawing up these four moods in battle array: they always admit of reduction to the foregoing moods by obverting the hypotheticals. Still, by the same process we may greatly decrease the number of moods of the Categorical Syllogism; and just as some Syllogisms are most simply expressed in Celarent or Cesare, so some Dilemmas are most simply stated with negative major premises--e.g., The example of a Simple Constructive Dilemma above given would run more naturally thus: _If the Tories win, the Government will not innovate; and if the Whigs, the Lords will not let them_: and similarly Demosthenes' Dilemma--_If Æschines joined, he is not consistent; and if he did not, he is not patriotic_. Moreover, the propriety of recognising Dilemmas with negative major premises, follows from the above analysis of the Dilemma into a combination of Conditional Syllogisms, even if (as in § 1 of this chapter) we take account of only four Moods of the Hypothetical Syllogism. In the rhetorical use of the Dilemma, it may be observed that the disjunction in the minor premise ought to be obvious, or (at any rate) easily acceptable to the audience. Thus, _Either the Tories or the Whigs will win; Either Æschines joined in the rejoicings, or he did not_; such propositions are not likely to be disputed. But if the orator must stop to prove his minor premise, the smacking effect of this figure (if the expression be allowed) will be lost. Hence the minor premises of other examples given above are only fit for a select audience. That _Either ghosts are not spirits, or they do not exert mechanical energy_, supposes a knowledge of the principle, generally taught by physical philosophers, that only matter is the vehicle of energy; and that _Either appearance is all, or there is substance beyond consciousness_, is a doctrine which only metaphysical philosophers could be expected to understand, and upon which they could not be expected to agree. However, the chief danger is that a plausible disjunction may not be really such as to exclude any middle ground: _Either the Tories or the Whigs win_, is bad, if a tie be possible; though in the above argument this is negligible, seeing that a tie cannot directly cause innovations. _Either Æschines joined in the rejoicings, or he did not_, does not allow for a decent conformity with the public movement where resistance would be vain; yet such conformity as need not be inconsistent with subsequent condemnation of the proceedings, nor incompatible with patriotic reserve founded on a belief that the rejoicings are premature and ominous.
