Truth centered epistemology puts truth at the center in more ways than one. For one thing, it makes truth a main cognitive goal of inquiry. For another, it explains other main epistemic concepts in terms of truth. Knowledge itself, for example, is explained as belief that meets certain other conditions, among them being true. And a belief is said to be rationally or epistemically justified or apt, which it must be in order to be knowledge, only if it derives from a truth-conducive faculty, an intellectual virtue. What defensible theories of truth are open to such truth-centered epistemology? That is our main question.

It is argued that knowledge is a form of action. It is a kind of successful attempt to attain the truth. The success must avoid a particular sort of “epistemic luck”. It must derive from competence rather than luck. Knowledge, then, is a judgment or belief that aims at truth and attains accuracy not by luck but through the agent’s cognitive adroitness, so that the attainment is apt. A higher grade of knowledge then requires that the agent attain aptly not only the accuracy (truth) but even the aptness of that first-order success. This more fully apt success is on a higher level of epistemic achievement, and in this respect is a special case of a general truth of performance normativity that applies across domains of human performance, whether in the arts, in sports, in the professions, and so on. An attempt in general reaches that higher level of achievement by being not only apt but fully apt.

This chapter has four parts. The first lays out Williamson's account of mental concepts and mental states, and his characterization of knowledge as the most general factive stative attitude. The second problematizes the account of mental states and the characterization of knowledge, and offers an alternative account of when a state is purely mental; according to this account, knowledge really is mental only by courtesy of the contained belief (an internalist intuition opposed to the externalism featured in the book). The third part reflects on possible sources and support for such a conception of the purely mental. The fourth and last part takes up the KK principle, Williamson's reductio of it, and the consequences of that for the possibility of reflective knowledge.

Ernest Sosa extends his distinctive approach to epistemology, intertwining issues concerning the role of the will in judgment and belief with issues of epistemic evaluation. Questions about skepticism and the nature of knowledge are at the forefront. The answers defended are new in their explicit and sustained focus on judgment and epistemic agency. While noting that human knowledge trades on distinctive psychological capacities, Sosa also emphasizes the role of the social in human knowledge. Basic animal knowledge is supplemented by a level of reflective knowledge focused on judgment, and a level of 'knowing full well' that is distinctive of the animal that is rational.

Our main topic is epistemic agency, which can be either free or unfree. This aligns with a distinction between two sorts of knowledge, the reflective and the animal. We first take up the nature and significance of these two sorts of knowledge, starting with the refl ective. In a second section we then consider the nature of suspension and how that relates suspension to higher orders of meta-belief. Finally, we consider a distinction in epistemology between animal competence and refl ective justification. All of these topics and distinctions are important for virtue epistemology, in ways to be considered.
