Philosophical Physicians: Aristotle

We’ve examined modern medical education from deontological and utilitarian perspectives; this week we’re tackling Aristotelian ethics. 

I’ve often felt like an outsider in medical training. As a medical student, I thought the discomfort would fade once I was fully “initiated.” Instead, it followed me into surgical residency. Everyone around me offered the same reassurance: discomfort is normal, especially in surgery training. It’s not questioned; it’s inherited. It’s treated as inevitable, a silent filter for who stays and who leaves.

Only later did I realize that my discomfort wasn’t just personal. It was philosophical. It raised a deeper question about what training is supposed to do: how much hardship refines character and how much erodes it? Who gets to draw that line?

To explore that question, we can turn to Aristotle (384-322) and his virtue ethics. Aristotle believed that the purpose of human life is eudaimonia, often translated as happiness, but more accurately understood as flourishing. He emphasized the importance of developing excellence of character (ēthikē aretē) as the means by which humans become capable of excellent action (praxis). 

Aristotle believed that most things go wrong at the extremes. Virtue, he argued, lives in the middle: The Golden Mean. This balance is anchored in his four cardinal virtues: prudence (practical wisdom), justice (fairness in dealings with others), courage (the fortitude to face difficulty), and temperance (moderation rather than excess). Courage isn’t charging headfirst into danger, but it isn’t freezing up either. Temperance isn’t denial, but it’s not indulgence. He also believed in the virtue of practical wisdom, or Phronesis: excellence in ethical decision-making. For Aristotle, virtues are the means and eudaimonia is the end. Eudaimonia is only achieved through Habituation, or repeated practice.

Many of us enter medicine with a kind of moral optimism. We believe, sometimes naively, that medicine is one of the clearest paths to becoming a better person. That it is a profession oriented toward wisdom, fairness, courage, and restraint. That through caring for others, under guidance and responsibility, we will develop these virtues ourselves and in turn deliver them to patients. Medicine, we think, is not just a career, but a moral apprenticeship.

Viewed through this lens, I believe modern residency training appears poorly ethically calibrated. Discomfort is applied broadly and uniformly, largely indifferent to individual context or capacity. Long hours, sleep deprivation, emotional suppression, and public humiliation persist not because they are scientifically grounded or ethically justified, but because they are dogma. The structure of training has changed little in nearly a century, despite profound changes in medicine and in our understanding of human development.

Aristotle would not ask whether this system produces technically competent physicians or even excellent patient outcomes. He would ask whether it cultivates virtue, whether it helps people become prudent, just, courageous, and temperate. By that standard, residency is not ethically neutral. It does not merely fail to cultivate these qualities, but it often works against them. Prudence is crowded out by exhaustion. Justice gives way to hierarchy and silence. Courage is reduced to endurance. Temperance becomes emotional suppression.

For Aristotle, the purpose of formation is not efficiency or replication, but the development of good people, people capable of sound judgment, moral clarity, and humane actions. Some discomfort is inevitable in any serious education, but when hardship is no longer calibrated towards growth, it ceases to educate.

I believe that by Aristotelian standards, modern residency training stands in direct conflict with human flourishing. The traits Aristotle identified as essential to a good life are frequently treated as liabilities rather than aims: wisdom and contemplation as hesitation, fairness as softness, moderation as lack of commitment.

If the goal of professional formation is excellence, not only in technical skill, but in character, then the problem is not that residency is hard: it’s that we’ve lost clarity about what that hardness is for.
