interesting and obviously relevant piece from the skptical enquirer posing the question, “Can the Sciences Help Us to Make Wise Ethical Judgments?”. a caveat to the conclusion they come to: “We are continually surrounded by self-righteous moralists who claim that they have the Absolute Truth, Moral Virtue, or Piety or know the secret path to salvation and wish to impose their convictions on all others. They are puffed up with an inflated sense of their own rectitude as they rail against unbenighted immoral sinners who lack their moral faith. These moral zealots are willing to repress or even sacrifice anyone who stands in their way. They have in the past unleashed conquering armies in the name of God, the Dialectic, Racial Superiority, Posterity, or Imperial Design. Skepticism needs to be applied not only to religious and paranormal fantasies but to other forms of moral and political illusions. These dogmas become especially dangerous when they are appealed to in order to legislate morality and are used by powerful social institutions, such as a state or church or corporation, to enforce a particular brand of moral virtue. Hell hath no fury like the self-righteous moral fanatic scorned.” could not have said it better myself. give it a read.
