摘　　要：逻辑可修正吗?逻辑真理可错吗?近期逻辑学界对此进行了激烈的讨论。逻辑可修正的争论实质是概念内涵与外延之争,而逻辑真理可错的争论却是认识之争,在其背后隐含着逻辑能否认识真理的问题。如果把逻辑真理等同于逻辑有效式,认为逻辑真理不是真理,则必然否认真理在逻辑中的存在。逻辑真理不应该是指那些在一个系统内有效的逻辑式,而是那些在系统内外都成立的有效式,因此逻辑真理是不可错的,是真理的一种形式,真理是能够在逻辑中找到的。Can logic be revisable？ May logical truth be false？ Recently some scholars have carried out related intense discussions.The controversy that logic may be revisable is essentially that of the connotation and extension of logical concept,while the controversy that the logical truth may be false is actually that of the understanding,which conceals a question：Does truth exist in logic？ If the logical truth is seen as logical valid formulae,and the logical truth is not considered as truth,the truth will be denied inevitably to exist in the logic.The logical truth should not refer to the logical valid formulae in a system,but to the universal valid formulae inside and outside the system,therefore the logical truth as one form of truth can not be false and truth exists in logic.
