According to Aristotle, happiness is the ultimate purpose of human life and consists of achieving, through the course of a whole lifetime, all the goods such as health, wealth, knowledge, and friends. For Aristotle, happiness is not a temporary state of being but a goal that can only be achieved at the end of life. He believed that happiness is not simply virtue but virtuous activity. Aristotle defined true happiness or "Eudaimonia" using four main points: happiness is a complete and sufficient good, it is the ultimate end or goal of human existence, it is self-sufficient, and it is attainable by living a life of virtue. Aristotle believed that happiness could not be achieved through excessive wealth, material possessions, or over-indulgence in vices, but at the same time, he understood that poverty created an inadequate environment for flourishing. To achieve happiness, one must possess other goods as well, such as friends, wealth, and power. Aristotles theory of happiness emphasizes the need to learn virtue through experience, with every individual taking a different path.
