Purity of Heart and Life

        this degrading vice. The sensitive nerves of the brain have lost their
      
      
        healthy tone by morbid excitation to gratify an unnatural desire for
      
      
         [110]
      
      
        sensual indulgence
      
      
      
      
        Moral pollution has done more than every other evil to cause the
      
      
        race to degenerate. It is practiced to an alarming extent and brings on
      
      
        disease of almost every description.
      
      
        Parents do not generally suspect that their children understand
      
      
        anything about this vice. In very many cases the parents are the real
      
      
        sinners. They have abused their marriage privileges, and by indul-
      
      
        gence have strengthened their animal passions. And as these have
      
      
        strengthened, the moral and intellectual faculties have become weak.
      
      
        The spiritual has been overborne by the brutish. Children are born
      
      
        with the animal propensities largely developed, the parents’ own stamp
      
      
        of character having been given to them. Children born to these parents
      
      
        will almost invariably take naturally to the disgusting habits of secret
      
      
        vice. The sins of the parents will be visited upon their children because
      
      
        the parents have given them the stamp of their own lustful propensities.
      
      
        Those who have become fully established in this soul-and-body-
      
      
        destroying vice can seldom rest until their burden of secret evil is
      
      
        imparted to those with whom they associate. Curiosity is at once
      
      
        aroused, and the knowledge of vice is passed from youth to youth,
      
      
        from child to child, until there is scarcely one to be found ignorant of
      
      
        the practice of this degrading sin
      
      
      
      
        The practice of secret habits surely destroys the vital forces of the
      
      
        system. All unnecessary vital action will be followed by corresponding
      
      
        depression. Among the young the vital capital, the brain, is so severely
      
      
        taxed at an early age that there is a deficiency and great exhaustion,
      
      
        which leaves the system exposed to disease of various kinds.
      
      
        If the practice is continued from the ages of fifteen and upward,
      
      
        nature will protest against the abuse she has suffered, and continues to
      
      
        suffer, and will make them pay the penalty for the transgression of her
      
      
        laws, especially from the ages of thirty to forty-five, by numerous pains
      
      
        in the system and various diseases, such as affection of the liver and
      
      
        lungs, neuralgia, rheumatism, affection of the spine, diseased kidneys,
      
      
        and cancerous humors. Some of nature’s fine machinery gives way,
