Our desire for immortality is killing us. We selfishly cling to the comfort of mythology at the expense of the real world. This must change. Yet we continue to sacrifice the substance of this life at the alter of faith in the afterlife, and we call this foolishness "holy"! How many billions of lives are our bronze-age beliefs worth? How many human sacrifices can we justify in assuaging our personal fears? Isn't the loss of even one life too high a cost for sustaining irrationally justified belief? In a technologically advanced society capable of producing weapons of mass destruction, the exchange rate between the real and the hoped-for is far too high. This is the take-home lesson of the World Trade Center. We can no longer afford to fool ourselves: religion must be done away with if mankind is to survive.
