Editing Deflationary theory of truth (section)

===Normativity of assertions===
[[Michael Dummett]], among others, has argued that deflationism cannot account for the fact that truth should be a normative goal of assertion. The idea is that truth plays a central role in the activity of stating facts. The deflationist response is that the assertion that truth is a norm of assertion can be stated only in the form of the following infinite conjunction:

<blockquote>One should assert the proposition that grass is green only if grass is green and one should assert the proposition that lemons are yellow only if lemons are yellow and one should assert the proposition that a square circle is impossible only if a squared circle is impossible and...</blockquote>

This, in turn, can be reformulated as:

:For all propositions P, speakers should assert the propositions that P only if the proposition that P is true.

It may be the case that we use the truth-predicate to express this norm, not because it has anything to do with the nature of truth in some inflationary sense, but because it is a convenient way of expressing this otherwise inexpressible generalization.
