"Ambiguity, multivalence, the fact that language simply cannot be regarded as a clear and final exposition of what it says, is central to both science and... literature. Why to science? ...you cannot make a single general statement about anything in the world which is really wholly delimited, wholly unambiguous, and divides the world into two pieces. ...you cannot say anything about a table or a chair which does not leave you open to challenge, "...I am using this chair as a table." ...the word "table" was not invented in order to bisect the universe into tables and non-tables. And if that is true of "table," it is true of "honor,"... "love,"..."gravity,"... "mass" and "energy" and everything else."
