силлогизм
noun Etymology: Middle English silogisme, from Anglo-French sillogisme, from Latin syllogismus, from Greek syllogismos, from syllogizesthai to syllogize, from syn- + logizesthai to calculate, from logos reckoning, word — more at legend 1. a deductive scheme of a formal argument consisting of a major and a minor premise and a conclusion (as in “every virtue is laudable; kindness is a virtue; therefore kindness is laudable”) 2. a subtle, specious, or crafty argument 3. deductive reasoning • syllogistic adjective • syllogistically adverb
/sil'oh-jiz`*m/ Deductive reasoning in which a conclusion is derived from two premises. The conclusion necessarily follows from the premises so that, if these are true, the conclusion must be true, and the syllogism amounts to demonstration. To put it another way, the premises imply the conclusion. For example, every virtue is laudable; kindness is a virtue; therefore kindness is laudable. Strangely, a syllogism can still be true if the premises are false. Compare inference rule.
