What is the purpose of life?

From The Ethics of Aristotle
Every art and every inquiry, every action and pursuit, aims at some good. The physician aims at health, the shipbuilder at a vessel, the general at victory. But what is the highest good — the end toward which all other ends are means? I call it eudaimonia — often translated as "happiness," though "flourishing" captures it better. It is not a feeling of pleasure, which comes and goes like weather. It is a condition of living well and doing well across a complete life. How do we achieve this flourishing? By fulfilling our function excellently. A knife flourishes by cutting well. A horse flourishes by running well. A human being flourishes by reasoning well — and by living according to reason in all domains of life. This means developing virtues: courage, justice, temperance, wisdom, generosity, proper pride. Each virtue is a mean between extremes — courage lies between recklessness and cowardice, generosity between extravagance and miserliness. But virtue alone is not enough. We also need external goods — some measure of health, resources, friendship, good fortune. The person who is virtuous but starving, isolated, or constantly battered by tragedy cannot fully flourish. This is simply honest about human nature. And we need activity. Virtue is not a possession but a practice. The person who could act justly but never does has not achieved justice. So: develop your capacities for excellence, exercise them in action, cultivate deep friendships, and accept that some things lie beyond your control. This is the path to a life worth living.
