在侦查思维中,由于刑事案件各个要素之间存在不同程度和类型的条件联系,从而使得假言推理的运用成为可能。侦查思维中的假言推理也称条件推理,是根据刑事案件中各个要素之间的条件关系构成的假言命题的性质所进行的推理。在侦查思维中,假言推理的应用很普遍,主要表现于推断案情事实、预测案情发展和检验侦查假说三个前后相继又相互联系的方面。根据条件关系的不同,假言推理分为充分条件假言推理、必要条件假言推理和充分必要条件假言推理,但是在侦查思维中运用较多的是前两种推理。侦查思维中的充分条件假言推理和必要条件假言推理都可以分为必然的推理形式和或然的推理形式,二者具有不同的认识论和方法论价值。在侦查思维中,正确而恰当地运用假言推理,必须遵守一些合理性原则,以期提高结论的真值度。
In investigative thinking, due to the different degrees and types of conditional links between the various elements of criminal cases, the use of hypothesis reasoning is made possible. Hypothetical reasoning in investigative thinking is also called conditional reasoning, which is based on the nature of the hypothetical proposition formed by the conditional relationship between the various elements in a criminal case. In investigative thinking, the application of hypothesis reasoning is very common, which is mainly manifested in the successive and interrelated aspects of inferring the facts of the case, predicting the development of the case and testing the hypothesis of investigation. According to the different conditions, the hypothesis reasoning is divided into full conditional hypothesis reasoning, necessary conditional hypothesis reasoning and necessary and sufficient condition hypothesis reasoning, but in the thinking of the mind to use more is the first two kinds of reasoning. The sufficient conditions in investigative thinking hypothesis reasoning and the necessary conditions hypothetical reasoning can be divided into a certain form of inference and a logical form of inference, the two have different epistemological and methodological value. In investigative thinking, the proper and proper use of hypothetical reasoning must comply with some principles of rationality, with a view to raising the truth of the conclusion.
