Prior to the Enlightenment, people who studied the natural sciences did so in order to know the nature of things so that they would know the appropriate way to treat them. During and since the Enlgihtenment, belief in the nature of things has been gradually lost until, now, it stands outside consideration. Science, having lost its purpose, serves the fancies and intentions of the politicians and business people who buy her services. In short, science serves those who love power and presume to strive for a world of their own design.
Science should not be taught apart from the quest for a propriety rooted in the nature of things. Only those students who have demonstrated reverence for the things that are should be introduced to the things that would change them.
