"Although we accept the inevitability of change, humans meet it with a lot of resistance. In most cases, change threatens those in positions of advantage and for the most part they are there in the first place to keep things the way they are. ...Yet at every turn, vested interests (those who have the most to gain in keeping things the way they are) oppose even technological changes... And so it goes.... 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... Better values, ideals, and behavior cannot be fully realized while there is still hunger, unemployment, deprivation, war, and poverty."
