A philosopher named A.J. Ayer would interpret Holbach's ideas. He believes that free will is compatible with determinism. He interprets Holbach's understanding of causal law, he argues that the laws of nature does not guarantee that something will happen a hundred percent. He wants to believe that human beings can be held responsible for their actions, if determinism is true. So he interprets determinism in a different way than Holbach, by simplifying the subject in his own words. He explains determinism in two ways: Logical necessity and Causal necessity. Logical necessity means something is true by definition. For example, a bachelor cannot be a bachelor if he is married. Causal necessity is factual correlation, for example dropping a ball.
