QUOTE : An elementary example: I can give a physicist, or a chemist, a book of poems. After study, the scientist can report back that the book weighs x kilograms, measures y centimeters in thickness, has been printed with ink having a certain chemical formula and bound with glue having another chemical formula etc. But scientific study cannot answer the question, "Are these good poems?" (Science in fact cannot answer any questions with "is" or "are" in them, but not all scientists realize that yet.)
