归纳推理的概称句解释

A Generic Interpretation for Induction Reasoning

要表达归纳推理结论的不确定性和刻画非单调的归纳推理,并非只能使用概率方法,用概称句和包含概称句的推理来刻画归纳推理是另一种可行且十分自然的方法。

Being different from deductive reasoning,the relation among the premises and the conclusion of an inductive inference is uncertain:for an inductive inference,when the premises are true,the conclusion may be but not must be true.Due to the uncertainty,inductive reasoning is non-monotonic.Since the beginning of modern inductive logic,the default method on the study of inductive reasoning is method of probability.However,from the perspective of history,we will find that using method OF probability to interpret inductive reasoning is just one of the possible ways.This paper points out that the conclusion of inductive reasoning,the idea of adding a certain probability to a inductive conclusion is to express the uncertainty and the monotonicity of inductive reasoning.To express these characteristics of the inductive reasoning,there is not only one method of probability.Generics interpretation is a feasible and very natural way.
