Novelty is used here in a way defined by Alfred North Whitehead:

Creativity is the principle of novelty. Creativity introduces novelty into the content of the many, which are the universe disjunctively. The creative advance is the application of this ultimate principle of creativity to each novel situation which it originates. The ultimate metaphysical principle is the advance from disjunction to conjunction, creating a novel entity other than the entities given in disjunction. The novel entity is at once the togetherness of the 'many' which it finds and also it is one among the disjunctive ' many' which it leaves; it is a novel entity, disjunctively among the many entities which it synthesises. The many become one, and are increased by one. In their natures, entities are disjunctively 'many' in process of passage into conjunctive unity... Thus the 'production of novel togetherness' is the ultimate notion embodied in the term concrescence. These ultimate notions of 'production of novelty' and 'concrete togetherness' are inexplicable either in terms of higher universals or in terms of the components participating in the concrescence. The analysis of the components abstracts from the concrescence. The sole appeal is to intuition. (Process and Reality, p. 26)
