Moreover, there is not a single set of epistemic virtues that characterizes 'good' knowledge, nor is there such a set that characterizes science. There are many different epistemic virtues and no universal rules about how they are to be applied in particular cases. Different virtues may dominate in different knowledge domains. In the 'same' domain there are neither universal nor domainspecific rules as to how to weigh different virtues. Different virtues may provide conflicting assessments of a knowledge claim. After glancing at contemporary epistemology in the analytic tradition, I conclude there is little interest in the question of metajustification of epistemic virtues. When it does come up, appeal is made to intuitions that are not grounded in philosophy , but in manifest life forms. Finally, I present pointers that should guide the application of the very general meta-epistemic virtues 'fitting with experience' and 'fitting with earlier knowledge': [i] rationality should be understood as bridled irrationality, [ii] knowledge should be evaluated in terms of rightness, not truth, [iii] any final grounding of epistemic virtues has to fall back on the manifest life forms
