【摘要】 皮尔士试图从科学分类法阐明逻辑学与其他科学之间的诸种关联,从而让我们看到一个既有所主张又有所保留、既充分包容又严格限定的逻辑科学:1.逻辑学作为实证科学,被归在哲学分部中,位居数学这一非实证科学之后;2.即便在哲学内部,逻辑学作为规范科学也不是处在第一位,形而上学倒是排在逻辑学之后,但在逻辑学之前存在着现象学这一哲学分支,而且在规范科学内部还有伦理学、美学位居逻辑学之前;3.逻辑学自身也是一个复杂的学科体系,其不仅关注论证有效性的批判论即今天通常意义上的逻辑,而且把理论意义上的语法和修辞也包括在内。更多还原

【Abstract】 Peirce tried to clarify the connections of logic with mathematics,philosophy and semiotics,in view of his classification of sciences.The science of logic has a specific role in this classification of sciences: Firstly,as an empirical science,logic falls into the category of philosophy and is placed right after mathematics;Secondly,even within philosophy,logic,ranking before metaphysics,is placed after phenomenology,esthetics and ethics;Thirdly,it is a complicated science which not only includes the critique of validity of argumentations but also the theoretic grammar and theoretic rhetoric.更多还原
