评普里斯特的“真矛盾”理论

On Priest's Dialetheism Theory

普里斯特建立亚相容逻辑系统LP试图刻画悖论和辩证矛盾等"真矛盾"理论。"真矛盾"理论的存在是普里斯特建立亚相容逻辑系统的动因。该系统对于已发现悖论而尚未解决的理论系统给予了合理的刻画,但悖论中的矛盾和辩证法中的矛盾分别属于逻辑矛盾和辩证矛盾。因此,用一个系统来刻画有本质区别的两种矛盾是不准确的,该系统并不能恰当地刻画辩证法中的矛盾。

Priest＇s paraconsistent logic system LP tries to depict ＂dialetheism＂ such as paradox and dialecticcontradiction.The existence of true contradiction was the reason why Priest constructed his paraconsistent logic system.LP has reasonably depicted the theory that paradox had found but not yet resolved in it.The contradiction in paradox is logical contradiction,and contradiction in dialectic is dialectic contradiction,it is not exact to depict these two kinds of essentially different contradictions by the same logical system because the system LP cannot depict the contradiction in dialectic.
