Aristotle, in his seminal Nicomachean Ethics, posits that the supreme good for human beings is eudaimonia, a state often translated as happiness but more accurately understood as flourishing or living well. This is not a fleeting emotional state but an enduring condition achieved through a lifetime of virtuous activity guided by reason. For Aristotle, eudaimonia is the ultimate end, pursued for its own sake, and all other goods, such as wealth, honor, or pleasure, are valuable only insofar as they contribute to this final aim. The achievement of this perfect happiness hinges on cultivating virtuous character and exercising our rational capacities, making the active life, rather than passive contemplation or mere feeling, the cornerstone of a truly good existence.
The foundation of Aristotle's argument for eudaimonia lies in his teleological worldview, which asserts that all things have a purpose or end (telos). Just as a sculptor's chisel is made for cutting and a physician's art aims at health, the function of a human being, he argues, is to live in accordance with reason. This capacity for rational thought distinguishes humans from other living creatures. Therefore, the good life, the life of eudaimonia, must involve the excellent performance of this distinctly human function. This excellence is achieved through virtue, which Aristotle divides into two categories: intellectual virtues, cultivated through teaching and learning (like wisdom and understanding), and moral virtues, developed through habit and practice (like courage, temperance, and justice). These moral virtues are not innate but are acquired by repeatedly performing virtuous actions until they become ingrained character traits. For instance, one becomes courageous by acting courageously in the face of fear, and temperate by practicing restraint in pleasures.
Aristotle further clarifies that virtue is a mean between two extremes of vice, one of excess and one of deficiency. Courage, for example, is the mean between the recklessness of rashness and the cowardice of fearfulness. Finding this mean is not a simple mathematical calculation but requires practical wisdom (phronesis), the ability to discern the appropriate course of action in specific situations. This emphasizes that eudaimonia is not about adhering to rigid rules but about developing the judgment to act rightly in the complex circumstances of life. A person who consistently makes these discerning choices, guided by reason and habituated to virtuous behavior, is on the path to flourishing. The active engagement with life, rather than withdrawal or passive reception of fortune, is therefore crucial.
Moreover, Aristotle acknowledges that external goods, while not the essence of eudaimonia, are necessary facilitators. Good fortune, health, friends, and even a certain level of material prosperity can contribute to a life of virtuous activity. It is difficult, for instance, to act courageously if one is constantly ill or to practice generosity without any resources. However, these external factors are secondary to the internal development of character and the exercise of reason. A person possessing all external goods but lacking virtue would not be considered to be living a good life. Conversely, someone with moderate external goods but a virtuous character and active engagement in rational pursuits could achieve eudaimonia. The emphasis remains on the quality of one's actions and character, not on the abundance of external possessions or passive experiences.
Ultimately, Aristotle's vision of perfect happiness is not a utopian ideal but a practical, attainable goal for any human being willing to cultivate their rational and moral faculties. It is a lifelong endeavor, requiring continuous effort, self-reflection, and engagement with the world through virtuous action. This active life, lived in accordance with reason and characterized by the excellent performance of one's human function, is the path to true flourishing, a state of being that constitutes the highest good and the most fulfilling existence. Eudaimonia is thus the reward for living an excellent human life, a life where our potential is fully realized through virtuous deeds and rational contemplation.
