Wellbeing refers to the overall state of flourishing, covering physical, mental, and moral dimensions—it is often measured objectively. Happiness is typically understood as a subjective, emotional experience, reflecting momentary or sustained feelings of pleasure or contentment. The good life, meanwhile, is an overarching concept that involves living in accordance with one’s values and virtues, often implying meaning, purpose, and a holistic approach to a life well-lived.

Similarities: • Both disciplines focus on flourishing and a full, satisfying life. • They agree that wellbeing involves more than mere pleasure or absence of pain, incorporating aspects like purpose and value.

Differences: • Psychology tends to use empirical methods and measurable indicators—often relying on subjective self-reporting and objective data—to assess wellbeing. • Philosophy focuses on normative analysis, exploring what constitutes a well-lived life through values, virtues, and ethical principles rather than solely on empirical evidence. • Philosophical approaches are more about analyzing how one ought to live, while psychological models emphasize understanding and promoting health and happiness as observed in behavior and experience.
