Problem:
There are two general classes of scientific laws. One class is correlational laws, which describe how classes of events vary together in some systematic way. For example, exercise tends to correlate positively with health. With such information, only prediction is possible. That is, if we knew a person's level of exercise, we could predict his or her health, and vice versa. A more powerful class of laws is causal laws, which specify how events are causally related. For example, if we knew the causes of a disease, we could predict and control that disease-as preventing the causes of a disease from occurring prevents the disease from occurring. Thus, correlational laws allow prediction, but causal laws allow prediction and control. For this reason, causal laws are more powerful than correlational laws and thus are generally considered far more desirable. Need Assignment Help?
