criticallyquestionsquestions 15-2615-26our society overestimates the contributions of science to the quest for knowledgeindependent of whether great strides have been made in the ability to predict natural events，knowledge at any deeper level，knowledge of things we cannot experience directly，is as illusory as eversuch knowledge is illusory because incompatible theories may always be postulated to explain observationshow can we know which one is correct?further observations may narrow the possibilities，but there are alwaysalternatives，at least in principlewho is to say that todays theories
