What is the history of enthusiasm?

It may come as a surprise to many people, when they first look up the word enthusiasm, to see that its original meaning has to do with passion for religion, rather than passionate or eager interest in general. A brief explanation of the word’s etymology should clear this up. Enthusiasm entered the English language around the beginning of the 17th century. It was borrowed from the Greek enthousiasmos, meaning “inspiration or possession by a god.” For the first two hundred or so years that it was used in English, enthusiasm was primarily employed to refer to beliefs or passions that related to religion. By the beginning of the 18th century, however, the word began to be used to describe having strong feelings or interest in secular matters.
