Full Idea
In the disquotational view of truth, what saves truth from being wholly redundant and so wholly useless, is mainly that it provides an ability to state generalisations like 'Everything Fermat believed was true'.
Gist of Idea
'True' is only occasionally useful, as in 'everything Fermat believed was true'

A Reaction
Sounds like the thin end of the wedge. Presumably we can infer that the first thing Fermat believed on his last Christmas Day was true.
