摘　　要：若限制一般意义的矛盾律,就会得到一种非亚氏(non-Aristotelian)逻辑,即弗协调(paraconsistent)逻辑。以弗协调逻辑系统C1为基础,对之进行语法和语义扩张,即可得到弗协调置信逻辑系统C1D。这种特殊的认知逻辑可以容忍认知冲突,若以之为基础逻辑,知识或信念的暂时不协调将不会导致逻辑上的无意义(不足道)。基于该系统的特异逻辑性质,相信一个陈述及其否定在逻辑上将变得并非不可能。该系统作为处理悖论的容悖路径,尽管在实质上没有排除掉悖论,但在那些认知悖论彻底解决之前,却可为理性认知提供一个可靠的逻辑基础。If the law of contradiction is restricted in a general sense, we will get a kind of non- Aristotelian logic： paraconsistent logic. In this expository paper, we provide a multi- agent doxic logic system C1D which can tolerate epistemic conflicts in a non-trivial manner. Based on it, temporary inconsistency of knowledge or belief will not lead to a meaningless or trivial logical outcome. It will be not impossible for us to believe a statement and its negation logically according to the specific nature of C1 D. Its tolerance for paradoxes does not eliminate those paradoxes in essence, but does offer us a logical foundation for rational cognition before we completely solve these epistemie paradoxes.
