We value justification and knowledge. But contextualist theories are deflationary. Contextualism about knowledge says that most of our everyday utterances of the form ‘S knows P’ are true, even though the strength of epistemic position in those instances does not meet our highest standards. In the same way, contextualism about flatness says that most of our everyday utterances of sentences of the form ‘X is flat’ are true, even though X’s surface may fall short of perfect flatness.
