VII. _Enthusiasm._ Very few people understand the true meaning of the word "enthusiasm," although they may use it quite frequently in ordinary conversation. Enthusiasm means far more than energy, activity, interest and hope--it means the expression of the "soul" in mental and physical actions. The Greeks used the word as meaning "inspiration; moved by the gods," from which arose the later meaning of "inspired by a superhuman or divine power." The modern usage is defined as: "Enkindled and kindling fervor of the soul; ardent and imaginative zeal or interest; lively manifestation of joy or zeal;" etc. A person filled with enthusiasm seems to move and act from the very centre of his being--that part which we mean when we say "soul." There is a wonderful power in rightly directed enthusiasm, which serves not only to arouse within one his full powers, but also tends to impress others in the direction of mental contagion. Mental states are contagious, and enthusiasm is one of the most active of mental states. Enthusiasm comes nearer to being "soul-power" than any other outward expression of mental states. It is allied to the soul-stirring impulse of music, poetry, and the drama. We can _feel_ it in the words of a writer, speaker, orator, preacher, singer or poet. Enthusiasm may be analyzed as Inspired Interest. As Walter D. Moody says: "It will be found that all men possessed of personal magnetism are very much in earnest. Their intense earnestness is magnetic." The best authorities agree that Enthusiasm is the active principle of what has been called Personal Magnetism.
