That is, when we attribute knowledge to someone, the context in which we use the term 'knowledge' determines the standards relative to which "knowledge" is being attributed (or denied). If we use it in everyday conversational contexts, the contextualist maintains, most of our claims to "know" things are true, despite skeptical attempts to show we know little or nothing. But if the term 'knowledge' is used when skeptical hypotheses are being discussed, we count as "knowing" very little, if anything. Contextualists use this to explain why skeptical arguments can be persuasive, while at the same time protecting the correctness of our ordinary claims to "know" things. This theory does not allow that someone can have knowledge at one moment and not the other, which would not be a satisfying epistemological answer. What contextualism entails is that in one context an utterance of a knowledge attribution can be true, and in a context with higher standards for knowledge, the same statement can be false. This happens in the same way that 'I' can correctly be used (by different people) to refer to different people at the same time.
