 Knowledge is among the many kinds of cognitive success that epistemology is interested in understanding. Because it has attracted vastly more attention in recent epistemology than any other variety of cognitive success, we devote the present section to considering it in some detail. But the English word “knowledge” lumps together various states that are distinguished in other languages: for instance, the verb “to know” can be translated into French either as “connaitre” or as “savoir”, and the noun “knowledge” can be translated into Latin as either “cognitio” or as “scientia”. Exactly how to individuate the various kinds of cognitive success is not something that can be determined solely by appeal to the lexicon of any particular natural language. The present section provides a brief survey of some of the kinds of cognitive success that are indicated by the use of “knowledge” in English, but this is not intended to signal that these kinds of cognitive success are all species of some common genus. Neither, however, is it intended to signal that these kinds of cognitive success are not all species of some common genus: at least some philosophers have taken there to be a genus, awareness, of which the various kinds of knowledge are all species, and with respect to which these various kinds may all be explained (see Silva 2019 for a defense of “awareness first” epistemology).
