摘　　要：分析哲学宣称可以通过对语言的逻辑分析解决传统的哲学问题,并倡导通过分析手段研究一切哲学问题。的确,分析精神已经在演绎推理和归纳推理两个方面获得了长足的发展,也取得了令人瞩目的成功。但与此同时,当用恰当的逻辑符号来重建哲学的概念和原则时,也遇到了难以克服的障碍,甚至出现了悖论等现象。例如,罗斯(Ross)的道义悖论、赫斯(Hesse)的确证悖论以及塔契-密勒(Tichy-Miller)似真性悖论等。这些悖论的出现是由于经典一阶逻辑中不加限制的添加原则,用舒尔茨(Schurz)的相关演绎逻辑能对这些悖论进行消解。From the foundation of it, modern analysis philosophy has already based philosophy on systems of exact logical reasoning and got a substantial development in the aspects of deductive and inductive reasoning. However, while reconstructing philosophic concept and principle with the exact logic sign, we have always been confronted with the obstinate and sometimes seemingly invincible phenomenon of paradoxes. This paper analyzes these paradoxes with common source. Then, it introduces the G. Schurz＇s Relevant Deduction and the solution of these paradoxes with the theory. Finally, this paper makes a comment on the theory.
