论悖论性语句与真值承担者

悖论性语句是具有悖论性质的语句,特点是从其真可以推出其为假,从其假可以推出其为真;陈述是陈述句所表达的内容,有一个陈述句就有一个陈述;命题是反映对象事实的思维形式,特点是要么真要么假。悖论性语句构成了陈述与命题的区别之所在。真值承担者的充分必要条件是,任一对象,如果是真值承担者,则它必须(i)′必须或者真或者假,不能既不真又不假;(ii)′必须或者不真或者不假,不能既真又假。悖论性语句不能符合真值承担者条件,因而陈述不能作为真值承担者;命题符合该条件,是真正的真值承担者。

Paradoxical Sentence and the Problem about Truth-Bearer

A paradoxical sentence is one that has paradoxical property,which is that truth of such a sentence can imply false itself,and vice versa.A statement is the content denoted by the corresponding declarative sentence,each declarative sentence corresponds to a statement.A proposition is a kind of thinking mode reflecting object's fact, which is either true or false.Paradoxical sentence belongs to statement but not to proposition,which distincts between statement and proposition.The sufficient and necessary condition of truth-bearer is that,for any objects,if they are truth-bearers,then they must be such that(i)?They are either true or false,not neither true nor false,and(ii)? They are either not-true or not-false,not both true and false.Since paradoxical sentences can't meet with the con- ditions above,statements can't act as the truth-bearer.Propositions meet with them,so they are genuine truth- bearer.
