 The motivation for the truth-assertion platitude is rather different. It looks at assertion as a practice, in which certain rules are constitutive. As is often noted, the natural parallel here is with games, like chess or baseball, which are defined by certain rules. The platitude holds that it is constitutive of the practice of making assertions that assertions aim at truth. An assertion by its nature presents what it is saying as true, and any assertion which fails to be true is ipso facto liable to criticism, whether or not the person making the assertion themself wished to have said something true or to have lied.
