ABSTRACT
In many of the affairs of ordinary life we explain an event by stating its cause. We say that the spring floods were caused by melting snow. We assume that had the snow not melted the floods would not have occurred. Thus we assume that there is a connection between the first event and the second, and we say that the first event brought about or determined the second. When such a relationship exists between two events we call the first event the cause and the subsequent event the effect.
