But, you and the car are the real action, the movement ot the landscape is only apparent. This is a movement that generates itself. It has its own life. It is not caused by another action. A walk, a jump, a run, a spin, a dialogue are all primary actions.
All actions generated by the thought process are primary.
This movement is reactionary. It has no life of its own. This is the movement caused by the persistent force of gravity or a primary action. The dancer is the primary action, whereas the dress, scarf, and her hair are all secondary actions. Unless there is first a primary action, there can be no secondary action.
