What sort of justification can be claimed for abduction? In this paper we reconstruct Peirce’s answer to this question. We show that in his early works on the logic of science Peirce provided an abductive justification of abduction, and that in his mature writings the early solution is enriched by a reference to the place abduction has in a typical scientific inquiry. Since abduction is the first stage of inquiry by which a hypothesis is suggested and which then has to be subjected to inductive testing, the fundamental abduction (ur-abduction) that justifies abduction has also to be subjected to a verification by means of a fundamental induction (ur-induction), namely that the abduction that abduction is valid is verified by an appeal to the history of science.

可以为绑架提出什么样的正当理由？在本文中，我们重构了皮尔斯对这个问题的回答。我们表明，在他关于科学逻辑的早期著作中，Peirce 为溯因提供了溯因证明，并且在他成熟的著作中，早期的解决方案通过引用溯因在典型科学探究中的位置而得到丰富。由于溯因是提出假设的第一阶段探究，然后必须对其进行归纳测试，因此证明溯因合理的基本溯因（ur -abduction）也必须通过基础归纳进行验证( ur -induction)，即溯因是有效的溯因是通过诉诸科学史来验证的。
