证据选择与归纳确证

Evidence Selecting and Inductive Confirmation

确证假说的证据是归纳确证中不可忽视的重要因素,证据的选择具有归纳逻辑视野的程序与规则。证据具有特定的经验内容,但在表达形式上又是一种语句;某语句被确认为相关假说的证据,既取决于个人对该语句及其竞争语句的主观概率评价,还取决于证据语句集的逻辑一致性;证据选择与证据的效用密不可分,而证据效用度在一定程度上体现了主观期望效用的测度。因此,何种语句可选作证据,何种语句优先选作证据,均需要确证活动的操作者依据一定的规则和程序来确认。

Evidence that confirms hypothesis is an important element that can't be neglected The selecting of evidence has its procedures and rules under the view of inductive logic Evidence has specific experimental contents, but it is also a sentence in expression form That some sentence is approved as evidence of relevant hypothesis is not only decided upon individual's subjective probability estimation on this sentence and its competitive ones but also upon the logical consistency of the evidence sentence class Though evidence selection and evidence function are intimate and can't be separated, the function degree of evidence expresses the measure of subjective expectation function at certain degree So that which kind of sentence can be selected as evidence and which kind of sentence has the individuals who are conducting confirmation according to some rules and procedures
