See also:DILEMMA (Gr. &Xuµua, a See also:double proposition, from bi- and aµ(36.vetv) , a See also:term used technically in See also:logic, and popularly in See also:common parlance and See also:rhetoric . (r) The latter use has no exact See also:definition, but in See also:general it describes a situation wherein from either of two (or more) possible alternatives an unsatisfactory conclusion results . The alternatives are called the " horns " of the See also:dilemma . Thus a nation which has to choose between See also:bankruptcy and the repudiation of its debts is on the horns of a dilemma . (2) In logic there is considerable divergence of See also:opinion as to the best definition . See also:Whately defined it as " a conditional See also:syllogism with two or more antecedents in the See also:major and a disjunctive See also:minor." Aulus See also:Gellius gives an example as follows:—" See also:Women are either See also:fair or ugly; if you marry a fair woman, she will attract other men; if an ugly woman she will not please you; therefore See also:marriage is absurd." From either alternative, an unpleasant result follows . Four kinds of dilemma are admitted: (a) See also:Simple Constructive: If A, then C; if B, then C, but either B or A; therefore C . (b) Simple Destructive: If A is true, B is true; if A is true, C is true; B and C are not both true; therefore A is not true . (c) Complex Constructive: If A, then B; if C, then D; but either A or C; therefore either B or D . (d) Complex Destructive: If A is true, B is true; if C is true, D is true; but B and D are not both true; hence A and C are not both true . The soundness of the dilemmatic See also:argument in general depends on the alternative possibilities . Unless the alternatives produced exhaust the possibilities of the See also:case, the conclusion is invalid . The logical See also:form of the argument makes it especially valuable in public speaking, before uncritical audiences . It is, in fact, important rather as a rhetorcial subtlety than as a serious argument . Dilemmist is also a term used to translate Vaibhashikas, the name of a Buddhist school of See also:philosophy . |
