认知主义的预设

The Presumptions of Epistemicism

认知主义对模糊性的研究在模糊性理论中独树一帜,其特点是,兼具强有力的论证性和强烈的反直观色彩。认知主义的这个特点说明,其背后有很多隐含的非平凡的哲学预设。通过论证可以发现,这些哲学预设之间存在强烈的内部张力。这种内部张力主要体现在认知主义对"模糊概念""情形"以及"相似性"的使用。这种张力的根源,主要在于两点:一是认知主义认为"模糊概念"独立于认知;二是认知主义对可能世界语义的内含性使用。

Epistemicism is very different among contemporary theories of vagueness. The two significant features of it are： first, its conclusions are extremely counter-intuitive; second, its arguments for those conclusions are extremely persuasive. This suggests that there are some non-trivial presumptions behind the arguments of epistemicism. Moreover, it is to be proved that there is huge tension among these presumptions. Which is mainly caused by the quasi-incongruent ways of use of important notions such as ＂concepts＂, ＂cases＂, ＂similarities＂ and so on. The conclusion is that epistemicism is not a stable theory of vagueness.
