<human>:  Who coined the term ‘emergence’?
<bot>: The term emergence was coined by the philosopher of science Thomas Kuhn. In his book, The Structure of Scientific Revolutions, he describes the concept of emergence as "the sudden appearance of novel properties and functions in a system which were not present in the system before." In other words, emergence is the process by which new properties and functions arise in a system as a result of changes in the system itself.
