Enthusiasm (Greek: enthousiasmos) 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, divines 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.
- Enthusiasm is the height of man; it is the passing from the human to the divine.
- Every production of genius must be the production of enthusiasm.
- Let us recognize the beauty and power of true enthusiasm; and whatever we may do to enlighten ourselves and others, guard against checking or chilling a single earnest sentiment.
- Nothing is so contagious as enthusiasm; it moves stones, it charms brutes. Enthusiasm is the genius of sincerity, and truth accomplishes no victories without it.
- Every great and commanding movement in the annals of the world is the triumph of enthusiasm.
- The most enthusiastic man in a cause is rarely chosen as a leader.
- Let us beware of losing our enthusiasms. Let us ever glory in something, and strive to retain our admiration for all that would ennoble, and our interest in all that would enrich and beautify our life.
