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. / We have not been everywhere in the universe, / 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.
