Since ancient times, the study of eudemonia has been paramount in the discipline of philosophy. Various schools of thought have developed ideas and theories that discuss the nature of this happiness and methods of attaining it.

A famous school of thought, which presents such theories, is that of Epicureanism; founded by Epicurus. Epicureanism asserts a strong focus on the necessity of ‘ataraxia’ and the fulfillment of necessary pleasures for the acquisition of eudemonia. The human condition is explored to understand the nature of happiness and discover methods of achieving this happiness, which according to Epicureanism, heavily involves ones beliefs and judgments, emotions, desires and virtue.
