　　他们相信，诸如灵与肉的问题，或更普遍而言，人类知识的性质等此类哲学关注，均是一些基本的人类问题，其探索性的哲学答案已构成一个必要的基础，其它所有的智力思辩均赖以建立其上。

　　74.The idea of an autonomous discipline called philosophy， distinct from and sitting in judgment on such pursuits as theology and science turns out， on close examination，to be of quite recent origin.

　　细作审视，我们便不难发现，一种被称为哲学的独立学科既有别于神学和科学诸般学科，并高高在上地对其予以评判的思想，其渊源却是甚为近期的事。

　　这些问题之所以带有政治性质，因为可避免地，围绕这些问题展开的急诊与其说是一种在客观冷静科研精神指导下对抽象问题的探索，倒不如说是一种学术上的权力斗争。在此斗争中，许多女学者中只是在现在才开始以众多的人数进入学术界的学术生涯和职业命运将处于存亡攸关的危急关头，与她们相伴随的是对人文理解作出一种独特贡献的机遇，这一贡献则很有可能成为消除我们社会中所存在的性别主义的一股重要影响。
