劳丹等人否认科学划界问题,盖尔纳认为波普尔的思想发展分为前期和后期,前期强调可证伪性,后期强调批评讨论。本文论证,波普尔的划界标准、可证伪性和可批评性是联系在一起的;通过猜测与反驳法或试错法,波普尔构造了一种统一的方法,在一个总体框架中把科学和人类行为理论和解释性理解连接在一起。 Laudan and others deny the issue of scientific demarcation, Gellner that Popper’s thought is divided into pre-and post-development, pre-emphasis on falsifiability, late emphasis on critical discussion. This paper argues that Popper’s demarcation criteria, falsifiability and criticism are linked together. Popper constructs a unified approach by guessing and refuting or trial-and-error, and in a general framework Science and human behavior theory and explanatory understanding linked together.
