George Berkeley

PHIL. But is it not the only proper genuine received sense? And, if Matter, in such a sense, be proved impossible, may it not be thought with good grounds absolutely impossible? Else how could anything be proved impossible? Or, indeed, how could there be any proof at all one way or other, to a man who takes the liberty to unsettle and change the common signification of words?

HYL. I thought philosophers might be allowed to speak more accurately than the vulgar, and were not always confined to the common acceptation of a term.
