答案                         The Purpose of Science
    Contrary to popular opinion, the purpose of science is neither to discover the ultimate "truth" , / nor to offer its findings as absolute and final. / Scientific theories are always subject to modification / if new evidence becomes available. / Science, as we have said, / attempts to accumulate data based on the available evidence. / It is often not known if or when additional evidence may be forthcoming. / Moreover, scientific findings reflect knowledge of the immediately known universe. / We have not been everywhere in the universe, / nor have we experienced other possible conditions different from those we know at present. / Thus, in keeping with the principle of objectivity, / science must deal with probability, not certainty, / and thus cannot present its findings as the absolute and final truth. / There is an extremely high probability that the sun will rise tomorrow, / but no one really knows for certain.
