Have you ever wondered what our future is like? Practically all people   61   a desire to predict their future   62  . People seem inclined to   63   this task using causal reasoning. First, we generally   64   that future circumstances are   65   caused or conditioned by present   66  . We learn that getting an education will   67   how much money we earn later and that swimming beyond the reef may bring an unhappy   68   with a shark.
    Second, people also learn that such   69  of cause and effect are probabilistic（概率）in nature. That is, the effects occur more often when the causes occur than when the causes are   70  , but not always.  71   , students learn that studying hard   72  good grades in most instances, but not every time. Science makes these concepts of causality and probability more explicit and   73   techniques for dealing  74   then more rigorously than does causal human inquiry. In looking at ordinary human inquiry, we need to  75   between prediction and understanding. Often, even if we don’t understand why, we are willing to act   76   the basis of a demonstrated predictive ability.
    Whatever the primitive drives   77   motivate human beings, satisfying them depends heavily on the ability to predict future circumstances. The attempt to predict is often played in a   78   of knowledge and understanding. If you can understand why certain regular patterns 79  , you can predict better than if you simply observe those patterns. Thus, human inquiry aims   80   answering both “what” and “why” question, and we pursue these goals by observing and figuring out.
