The role of testimony in the transmission and generation of knowledge has been debated vigorously in contemporary epistemology. More recently, types other than propositional knowledge are also being discussed, among them know-how. No special attention, however, has been paid so far to tacit forms of know-how. In this article, I am arguing for the thesis that testimony, if understood in an inclusive way, can play a central role in the transmission and generation of tacit know-how. This thesis is embedded in (...) a virtue-theoretic framework: next to testimony, successful acquisition of tacit know-how crucially depends on the relationship between teacher and student and the virtues they both display.
