Full Idea
An isolated judgement is never 'true', never knowledge; only in connection and relation of many judgements is there any surety.
Gist of Idea
Judgements can't be true and known in isolation; the only surety is in connections and relations

A Reaction
It actually seems impossible to state an isolated judgement in language without having a mass of presuppositions and beliefs to support it. I don't think the full holistic thesis about language follows, however.
