Enthusiasm does not necessarily connote hysteria or sentimentalism. The unstable enthusiast is a familiar type, the man who has another object of eagerness and loyalty each week. Mark Twain describes the type in the person of his brother, who had a dozen different ambitions a year. But enthusiasm may be a long-sustained devotion to a single ideal. A curious instance of it was seen in the case of an Armenian scholar who, so it is reported to the writer by a student of Armenian culture, spent forty years in mastering cuneiform script in order to prove that the Phrygians were descended from the Armenians, and not _vice versa_.
Shelley could kindle the spirit of revolution in thousands who would have been bored to death with the same fiery doctrines in the abstract and cold pages of Godwin, from whom Shelley derived his ideas of "political justice." The enthusiast, since he instinctively likes to share his emotions, not infrequently displays an intense desire for leadership, not so much that he may be a leader as that he may win converts to his own cause or creed. Such a personality finds its satisfaction in some form of proselyting zeal, be it for a religion, for a favorite charity, for good books, poetry, or social justice. A well-known literary scholar who died recently was thus described by one of his former students:
Dr. Gummere was not a teacher; he was a vital atmosphere and his lectures, as one considered them from an intellectual or emotional angle, were revelations or adventures. There never were such classes as his, we believed. Who could equal him in readiness of wit? Where was there such a raconteur? Who else could put the feel of a poem into one's heart? ... His voice was very deep, and exceedingly free and flexible. It always seemed to brim up as from a spirit overflowing. Everything about him was individual and spontaneous. He was perhaps most like a powerful river that braced one's energies, and carried one along without the slightest desire to resist.[1]

THE NEGATIVE SELF. All the types of personality or self that have thus far been discussed are in some way positive or assertive. But the self may be exhibited negatively, in a shrinking, not only from observation, but from any positive or pronounced action. This has already been noted in connection with submissiveness. Most people in the presence of their intellectual and social or even their physical superior, experience a sense of, to use McDougall's term, "negative self-feeling." In some people this negation or effacement of the self is a predominant characteristic.
