假言判断既是复合判断的一种重要形式,也是学习假言推理的阶梯和前提,正确区分假言判断中的条件关系,对于防止思想片面性,提高认识能力和表达能力,都是重要的。但是学生在学这些条件关系时往往很感棘手,而不少报刊上也往往众说纷纭,莫衷一是。因此,识别假言判断中的条件关系,是掌握逻辑知识的重点和难点之一。假言判断所反映的事物之间的条件联系,有充分条件、必要条件和充分必要条件三种,
Hypothesis judgment is not only an important form of compound judgment, but also a ladder and premise for learning hypothetical reasoning. It is important to correctly distinguish conditional relations in hypothetical judgments from preventing one-sidedness of thinking and improving cognitive ability and expressive ability. However, students are often very troubled when learning these conditions, and many newspapers and magazines are often different opinions. Therefore, identifying the conditional relationship in hypothesis judgment is one of the key and difficult points in mastering logic knowledge. The conditional connection between the things that the hypothetical judgement reflects has sufficient conditions, necessary conditions and sufficient and necessary conditions.
