Contextualism in Philosophy: Knowledge, Meaning, and Truth

Any utterance of a sentence occurs within a context. The speaker and the listener have certain presuppositions, a given background. Most sentences are embedded in a discussion, speech, an argumentation, or a paragraph. Contextualism in epistemology maintains that whether one knows is relative to the context of the sentence token.
Twelve essays and an introduction by the editors scrutinize contextualism in epistemology and in the philosophy of language. The debate about contextualism and its consequences is continued in "Contextualism in Philosophy" on a high level. Although, I think, no contextual matter will be settled with these papers, they drive the debate to new fields, the reader gets a deep insight in topical issues.
My exclamation marks in the table of contents for the contributions most illuminating for me are at Kent Bach: "The Emperor's New 'Knows'", Jonathan Schaffer: "What Shifts? Thresholds, Standards, or Alternatives?", and Jason Stanley: "Semantics in Context".
If you want to keep up with the current debate in contextualism you have to study this book completely. Caution: it will take some time and effort.
