What was classical genetics?

I present an account of classical genetics to challenge theory-biased approaches in the philosophy of science. Philosophers typically assume that scientific knowledge is ultimately structured by explanatory reasoning and that research programs in well-established sciences are organized around efforts to fill out a central theory and extend its explanatory range. In the case of classical genetics, philosophers assume that the knowledge was structured by T. H. Morgan’s theory of transmission and that research throughout the later 1920s, 30s, and 40s was organized around efforts to further validate, develop, and extend this theory. I show that classical genetics was structured by an integration of explanatory reasoning (associated with the transmission theory) and investigative strategies (such as the ‘genetic approach’). The investigative strategies, which have been overlooked in historical and philosophical accounts, were as important as the so-called laws of Mendelian genetics. By the later 1920s, geneticists of the Morgan school were no longer organizing research around the goal of explaining inheritance patterns; rather, they were using genetics to investigate a range of biological phenomena that extended well beyond the explanatory domain of transmission theories. Theory-biased approaches in history and philosophy of science fail to reveal the overall structure of scientific knowledge and obscure the way it functions.

从张荫麟问题看朱熹的格物致知之旨

“格物致知”是朱熹理学范畴体系中的重要范畴。历来研究者们对之训解颇多。上世纪30年代,史学家张荫麟先生在对冯友兰先生的《中国哲学史》(下卷)的评论中,从为学方法论角度,质疑朱熹的“格物致知补传”思想之合理性。而实则朱熹的“格物致知”说本身是与其理学本体论相呼应的,其所要格之“物”主要是“日用问应事处”,即是人伦日用之事物;致知之“知”主要是对“至善”之所在的认识,即是明乎先天已存在于己的儒家的道德之善。“格物致知”的认识论工夫最终所要达到目标仍是为人寻到先天存在的道德伦理价值．以作为自己的安身立命之准则。从而认识论工夫与修养工夫两者在目标上是统一的。     

教育目的观的成因探析

以知识为中心的教育目的观是导致我国大学生现代适应性差的重要原因,而这种教育目的观的形成也有着多方面的原因。本文从教育发展的历史和现实两个角度对此进行了探讨,提出历史上的“重社会,轻个人”和现实中的“重记忆,轻创造”是重要的两点。为此,作者提出要塑造现代化的人,首先必须更新教育目的观。
