Artificial Intelligence and the Measurement of Virtue

Phronimos Spectrum: AI for Virtue Assessment refers to a digital system that uses artificial intelligence to analyze human actions, decisions, and behaviors through the lens of virtue ethics, especially Aristotle’s moral theory from the Nicomachean Ethics.

The central idea is that an action is not evaluated only by its outcome, but also by intention, context, measure, character, and practical wisdom — that is, phronesis. The system would function as a tool for moral interpretation: it receives a concrete situation, identifies the possible options, and estimates which of them comes closest to virtuous action.

“Phronimos” refers to the prudent and practically wise person, the one who knows how to choose well in concrete situations. “Spectrum” suggests that virtue is not treated simplistically, as a black-and-white verdict, but as a range of assessment between extremes: deficiency, excess, and the right measure. For example, courage can be understood as the mean between cowardice and recklessness.

Thus, Phronimos Spectrum could assess whether an action expresses virtues such as courage, temperance, justice, generosity, honesty, or prudence, or whether it slips into vices such as cowardice, imprudence, greed, injustice, or emotional excess.
