Enthusiasm
Enthusiasm originally meant inspiration or possession by a divine afflatus or by the presence of a god. Johnson's Dictionary, the first comprehensive dictionary of the English language, defines
enthusiasm as "a vain belief of private revelation; a vain confidence of divine favour or communication." In current English vernacular the word simply means intense enjoyment, interest, or approval. Originally, an
enthusiast was a person possessed by a god. Applied by the Greeks to manifestations of divine possession, by Apollo, or by Dionysus, the term enthusiasm was also used in a transferred or figurative sense. Socrates taught that the inspiration of poets is a form of enthusiasm. Its uses were confined to a belief in religious inspiration, or to intense religious fervour or emotion. Thus, a Syrian sect of the 4th century was known as the Enthusiasts. They believed that "by perpetual prayer, ascetic practices and contemplation, man could become inspired by the Holy Spirit, in spite of the ruling evil spirit, which the fall had given to him". From their belief in the efficacy of prayer, they were also known as Euchites.
