According to an influential view, asserting a proposition involves undertaking some “commitment” to the truth of that proposition. But accounts of what it is for someone to be committed to the truth of a proposition are often vague or imprecise, and are rarely put to work to define assertion. This article aims to fill this gap. It offers a precise characterisation of assertoric commitment, and applies it to define assertion. On the proposed view, acquiring commitment is not sufficient for asserting: To assert, commitment must be acquired by explicitly presenting a proposition as true.

断言的定义：承诺和真理

根据一种有影响力的观点，主张一个命题需要对该命题的真实性做出某种“承诺”。但是，对于某人对某个命题的真实性的承诺是什么的描述往往是模糊或不精确的，并且很少被用来定义断言。本文旨在填补这一空白。它提供了断言承诺的精确特征，并将其应用于定义断言。根据提出的观点，获得承诺不足以断言：要断言，承诺必须通过明确提出一个命题为真来获得。
