《思想的力量:哲学导论》
314. 分析哲学
何谓分析(analysis):简言之,哲学上的分析就是把复杂的命题或概念解析为简单的。
例:方的圆是不存在的事物。经过分析后,就成了下面这个比较简单的命题:没有方式圆。
315. 分析哲学概览
分析作为一种哲学方法,是如此之重要。
伯特兰-罗素(Bertrand Russell,1872-1970)曾经赞同过唯心主义的形而上原则。罗素研究数学因而对哲学产生兴趣。他想要对“数”和“数学”作出令人满意的描述。他开始感到,绝对唯心主义哲学中有两个假定十分可疑,而它们又是互相关联的:1)所有明天都具有主谓结构;2)一个对象同另一个对象的关系,属于这个对象的根本性质的一部分。罗素认为这两个假定和以下事实不相容:世界上的存在者是多而不是一(因此绝对唯心主义理论主张,存在者就是一,即绝对)----这意味着它们和数学不能相容。
罗素读到黑格尔关于数学的论述时,感到苦恼,因为他觉得黑格尔的说法显得既无知又愚笨。于是她放弃了绝对唯心主义。
