真之多元论的混合合取难题

The Problem of Mixed Conjunctions for Truth Pluralism

真之多元论认为不同的领域有不同的真性质。混合合取的合取支由不同领域的命题所构成,从而具有不同的真性质。多元论需要解释混合合取具有何种真性质。尽管多元论有若干解决办法,如假设逻辑领域特有的真性质、假设合取命题特有的真性质、假设某种普遍的真性质,但都存在一定的问题。混合合取仍旧对多元论构成挑战。另外,强一元论面临辖域问题,即,适真性的范围较窄。相比较而言,弱一元论优于多元论和强一元论。

Truth pluralism holds that there are different truth properties in different domains.The conjuncts of a mixed conjunction are from different domains,and hence have different truth properties.Truth pluralism needs to explain what truth property the mixed conjunction has.Though truth pluralism has come up with a few solutions,e.g.by positing a truth property specific to the logical domain,or a truth property exclusively for conjunctions,or some kind of generic truth property,there are certain shortcomings.The problem of mixed conjunctions is still a challenge for truth pluralism.Besides,strong monism faces the scope problem,i.e.has a narrow range of truth-aptitude.In comparison,weak monism is superior to pluralism and strong monism.
