"Until scientific inquiry came of age, human beings could not comprehend their relationship to the physical world, so they invented their own explanations. These explanations tended to be simplistic and in many cases, harmful. For example, if one knows a tidal wave is approaching and chooses to stay and pray for deliverance rather than leaving, this could be detrimental to his/her survival... Scientists ask the question “what do we have here?” and then they proceed to do experiments to determine the nature of the physical world... What is considered appropriate behavior today may be considered un-sane in the future... Better values, ideals, and behavior cannot be fully realized while there is still hunger, unemployment, deprivation, war, and poverty."
