In 1993, Karen Harding, a philosopher wrote a paper, Causality then and now: Al-Ghazali and QM. She remarked:
In both cases, and contrary to common sense, objects are viewed as having no inherent properties and no independent existence. In order for an entity to exist it must be brought into being either by God (al-Ghazali) or by an observer (the Copenhagen interpretation).
This doctrine of al-Ghazali is called Occasionalism. It states that actual entities are continuously created, decreated, and recreated by God.
Whitehead admits a similar description of his events. They are actualized and deactualized, that is created and decreated. He also called these 'occasions'.
The family resemblence between his doctrine and that of al-Ghazali and the name he gave to the moment of a creative, actualising act suggests that he might have been influenced by al-Ghazali.
