We might think that thought experiments are at their most powerful or most interesting when they produce new knowledge. This would be a mistake; thought experiments that seek understanding are just as powerful and interesting, and perhaps even more so. A growing number of epistemologists are emphasizing the importance of understanding for epistemology, arguing that it should supplant knowledge as the central notion. In this chapter, I bring the literature on understanding in epistemology to bear on explicating the different ways (...) that thought experiments increase three important kinds of understanding: explanatory, objectual and practical.

Many philosophers believe that aesthetic testimony can provide aesthetic knowledge. This leaves us with the question: why does getting aesthetic knowledge by experience – by seeing a painting up close, or witnessing a performance first-hand – nevertheless seem superior to aesthetic testimony? I argue that it is due to differences in their epistemic value; in the diversity of epistemic goods each one provides. Aesthetic experience, or the experience of art or other aesthetic objects, affords multiple, distinctive epistemic goods whereas aesthetic (...) testimony affords less. In particular, it provides aesthetic knowledge of truths, a kind of propositional knowledge, as well as aesthetic knowledge of things, a kind of non-propositional knowledge. Although aesthetic experience is superior because it has more epistemic value, this doesn’t mean that aesthetic testimony provides weaker justification for aesthetic belief than aesthetic experience; the difference is evaluative, not normative. In this way, we can explain a key pessimistic intuition about aesthetic testimony – that it is inferior to aesthetic experience – whilst preserving the optimistic view that aesthetic testimony makes aesthetic knowledge available to others. The superior epistemic value of first-hand aesthetic experience is compatible with a number of important observations about aesthetic testimony, including the importance of aesthetic trust. (shrink)
