Perception of relationships is the cornerstone of civilization. By understanding how certain phenomena depend on others we learn to predict the consequences of our actions and to manipulate our environment. Most relationships we know of are based on empirical observations. Although some relationships are postulated on theoretical grounds, usually the theories themselves were originally obtained from empirical observations. And even these relationships often need to be empirically tested.
