Peter Baumann develops and defends a distinctive version of epistemic contextualism, the view that the truth conditions or the meaning of knowledge attributions of the form "S knows that p" can vary with the context of the attributor. The first part of the book examines arguments for contextualism and develops Baumann's version. It begins by dealing with the argument from cases and ordinary usage, and then addresses "theoretical" arguments, from reliability and
from luck. The second part of the book discusses the problems contextualism faces, to which it must respond, and provides an extension of contextualism beyond epistemology. The third part of the book is
focused on some major objections to contextualism and alternative views, namely subject-sensitive invariantism, contrastivism and relativism.
