every distinct Quality, that were discovered in any Matter by any

signified by the common Name given it, it must follow, that Men
must suppose the same Word to signify different Things in different
Men: since they cannot doubt, but different Men may have dis-
covered several Qualities in Substances of the same Denomination,
which others know nothing of.
