Great Idea 1
Idea 1: Cause and effect
The Causality Principle has played an important role in the development of the theory of knowledge. It states that all real events necessarily have a cause. The principle indicates the existence of a logical relationship between two events, the cause and the effect, and an order between them: the cause always precedes the effect. An important property of the principle is that it entails predictability. If a force is applied on a body then it will cause the body to accelerate. Without a force, there cannot be an acceleration.
