有效性

在逻辑中,如果一个论证不能从真前提中得出假结论,则论证的形式是完全有效的。一个论证若被称为是有效的,则如果在其中所有前提都为真的每个模型中,结论也是真的。例如:“所有A是B;有些A是C;所以有些B是C”是有效形式。

  • 一个逻辑公式被称为是有效的,如果它在所有释义(也叫做结构或模型)下都是真的。参见模型论或数理逻辑。
  • 一个重言式,或重言公式,是真值泛函有效的。不是所有量化逻辑的有效的公式都是重言式。参见真值表。

Validity 有效性

In logic, an argument is valid if and only if it takes a form that makes it impossible for the premises to be true and the conclusion nevertheless to be false. It is not required that a valid argument have premises that are actually true, but to have premises that, if they were true, would guarantee the truth of the argument's conclusion. A formula is valid if and only if it is true under every interpretation, and an argument form (or schema) is valid if and only if every argument of that logical form is valid.
