There are many quizzes based on the four elements, but most are rather light on research. This quiz will analyze your personality using ancient theories such as the 4 Temperaments, the 4 Cardinal Virtues, and the writings of Plato and Aristotle, as well as modern theories such as the Myers Briggs (MBTI), the Enneagram, etc. So are you Earth, Water, Air, or Fire? (The quiz now includes mixed elements.)
