赫茲勒教授认为,当前世界人口增长率上升非常之快,因此引起了危机;但是一般人为了某些原因还不觉察到,或不关心到,这个迫切的危險。人們所以犯这样錯誤,是因为他們受了錯誤价值的欺騙;“有相当多的事例証明人們仅仅关心人口数量问题,这是可悲的。” Professor Herzleh believes that the rate of current world population increase has risen so rapidly that it has caused a crisis. However, it is an urgent danger that most people are not aware of or care about for some reason. People make such mistakes because they are deceived by false values; “there is a considerable body of evidence that people are merely concerned about the population size. It is pathetic.”
