从绿蓝问题看波普尔对归纳问题的解决

On Popper’s Solution to the Inductive Problem from the Perspective of Grue Problem

归纳问题是近代以来最基本的哲学问题之一。波普尔首先把归纳问题转化为假说的选择与接受问题,然后在其证伪主义范式下对其作了正面解答。波普尔的解决方案在经验层面上诉诸可证伪度标准,或者说潜在证伪者类标准,但该标准没能解决绿蓝问题。在方法论层面上,波普尔用被他拒斥的“狭隘合理性”规则来攻击归纳,从而陷入了不协调的窘境。

Inductive problem is one of the most basic modern philosophical problems. Popper transfers inductive problem into one of hypothesis choosing or holding. Then he tries to solve the hypothesis-choosing problem in his falsification paradigm. Popper's solution is to appeal to the rule of falsification degree or latent falsification set at the experience level. But the rule can’t solve the grue problem. At the methodological level, Popper attacks induction with the rule of narrow rationality that he refutes. So he plunges himself into the predicament of inconsistency.
