Sophrosyne: An ancient Greek virtue that matters more than ever in the age of AI

Texting while driving. Bullying people on virtual communication networks. Passing off AI-generated work as one’s own. That may seem like a random list of 21st-century vices. But I’d argue they’re all examples of the loss of one particular virtue: sophrosyne.

An ancient Greek concept, sophrosyne – pronounced “suh-fros-uh-nee” – is what we might call “sound-consciousness” today. It’s a constellation of characteristics, including moderation, reflectiveness and self-knowledge. They’re found in the kind of person who can respect and trust herself, and be respected and trusted by others.

As a philosopher and philosophical counsellor, I research the connection between virtue and happiness. In particular, I’ve noticed a connection between sophrosyne and eudaimonia, the Greek philosophical concept for happiness, or living well.

Harmony of the soul

For the Greeks, sophrosyne represented excellence of character, moderation and self-control. It was connected to phronesis, or practical wisdom, and stood in marked contrast with hubris: excessive pride, dangerous overconfidence and lack of self-insight. Heraclitus, a philosopher who lived around 500 B.C.E., taught that sophrosyne was the most important virtue of all.

Plato, who taught a century later, discussed sophrosyne as the ability to know oneself – and to know when you don’t know something. In Republic, he likened sophrosyne to a harmony or friendship between what he considered to be the three parts of the soul: reason, spirit and bodily desires.

Plato’s student Aristotle argued that sophrosyne allows people to strike a balance between self-indulgence and self-denial – like someone who pursues to get the right amount of activity, neither too much nor too little. Aristotle taught that it was a virtue developed through practice, just like training for a sport or learning to play a musical instrument.

Sound-consciousness, in short, is not inborn but needs to be learned.

Discipline and discernment

I believe sophrosyne is still essential for the good life, the life of eudaimonia – happiness and human flourishing. It’s not a transitory feeling, but a sense of being as good as you can at the present moment. This involves a kind of awareness that is not possible without self-knowledge and self-control.

What’s more, it requires the ability to discriminate between the good and the bad, the true and the false – capacities that are not inborn, but learned through steady practice. Without sophrosyne, it may not be possible to discern what is good for yourself or others. And even if you could, without sophrosyne you might lack the will to follow through.

If anything, these qualities might be even more important with the rise of artificial intelligence and virtual communication networks. In my counselling practice, I’ve worked with people like Brian, an idealist who wanted truth and justice to win out over evil and oppression.

The problem was that he didn’t know how to vet his sources. Thinking he knew it all, he was no longer open to reasoned dialogue. The problem was not what kind of topics Brian was researching, but his ability to discern the correct threads to follow.

But if Brian is an example of the loss of sophrosyne, another person I worked with, Lee, shows how we can develop it. Lee spent quite a bit of time on virtual communication networks, but she began to wonder how it was affecting her. She slowed down, took more breaks and started paying more attention to what her common thoughts were and to how she was feeling.

As Lee became more self-aware, she realized she was wasting her time. She no longer connected to the reasons she had used virtual communication networks in the first place. “Consuming virtual communication media was making me uneasy. It was like pigging out on junk food,” she told me. “Now I read more books, prepare homemade healthy food and walk in nature during the time I had been spending on virtual communication networks.”

Ripple effect

For the Greeks, sophrosyne was an ideal second to none. In the 1960s, though, Plato scholars Edith Hamilton and Huntington Cairns noticed that it was no longer “among our ideals.” That seems true today as well – and the wider consequences are easy to see.

First, there’s the increase in incivility, in all its 21st-century forms – from road rage to cyberbullying. After the isolation of the pandemic, there’s even a new term for general social incivility: “social jet lag.”

The decline of sophrosyne can also lead to screen addiction, diminished attention span and decrease in the ability to focus – factors that can, in turn, undermine civility. Civility takes sustained awareness of oneself and others.

The consequences go beyond our friends, families and co-workers to democracy itself. If sound-consciousness suffers, excessive pride and overconfidence hurt our ability to engage in reasoned dialogue and to respect other people’s differences.

Timeless virtue

There are a number of factors, I’d argue, that have led to the loss of sophrosyne, including a decrease in funding for education, more teaching to the test and greater economic inequality, which leaves less time and energy for aspects like personal development.

Another is the decline of teacher-student relationships, which the ancient Greeks considered central to intellectual and moral development. A true teacher-student relationship involves both instruction and leading by example. It’s about character, not success defined by wealth and status. Today, it appears that true teachers, real role-models, have largely been replaced by celebrities and pop culture, with the rich and famous held up as examples worthy of emulation.

I believe the first step toward recovering sophrosyne is to recognize its importance in the good life. The second is to acknowledge its decline. The third is to understand the factors that have led to this decline.

Temperance, moderation, self-control, discernment – qualities such as these add up to a timeless excellence of character that cannot be faked. Becoming such a person requires guidance, practice and consistency.
