Science cannot tell you

"There is a creeping danger of equating science with rationality, but what is beyond science is not necessarily irrational. Science cannot tell us for instance whether a poem or work of literature or a work of art and music is good or beautiful. Science can tell us that if you put strychnine into your grandmother’s tea it will kill her, but science cannot tell you whether it is morally right to do so." -- John Lennox
