A syllogism with an unstated major or minor premise , or even an unstated conclusion , needs to be examined with care because the omitted statement may contain an inaccurate generalization .

有时大前提并没有说明，需要仔细检查没有说明大前提或小前提，甚至是结论的三段论，因为省略的说明可能包含不准确的归纳。

This model is less constrained than the syllogism and makes allowances for the important elements of probability , backing , or proof for the premise and rebuttal of the reader 's objections .

这种模式的限制比三段论少，并为前提的证明、支持或可能性元素和反驳读者的反对留有余地。

Deductive reasoning often utilizes the syllogism , a line of thought consisting of a major premise , a minor premise and a conclusion ; for example , all men are foolish ( major premise ) ; smith is a man ( minor premise ) ; therefore , smith is foolish ( conclusion ) .

演绎推理通常采用三段论，一个由大前提，小前提和结论组成的思维过程，例如，所有的男人都是愚蠢的（大前提）；史密斯是男人（小前提）；因此，史密斯是愚蠢的（结论）。

If for instance we take the syllogism ( not as it was understood in the old formal logic , but as its real value ) , we shall find it gives expression to the law that the particular is the middle term which fuses together the extremes of the universal and the singular .

譬如，我们试取推论来说（不是指旧形式逻辑的三段论法，而是指真正的推论），我们可以看见推论是这样的一个规定，即特殊是普遍与个别这两个极端结合起来的中项。
