Daily Inspiration Quote by Thomas Aquinas

"Justice is a certain rectitude of mind whereby a man does what he ought to do in the circumstances confronting him"

About this Quote

Justice, for Aquinas, isn’t a courtroom outcome or a vibe; it’s mental posture. “A certain rectitude of mind” sounds pious until you realize how demanding it is: justice begins before any action, in the disciplined alignment of will and reason toward the good. He’s quietly relocating morality from external compliance to interior formation. The person who “does what he ought to do” isn’t merely obeying rules; he’s trained himself to see what is owed and to whom, then to choose it even when it costs.

The phrase “in the circumstances confronting him” is the key that keeps Aquinas from being a brittle legalist. He writes in a medieval world thick with hierarchy, obligation, and communal life, where ethics had to function in messy realities: famine, war, unequal stations, competing duties. Aquinas nods to prudence without naming it. Justice isn’t improvisation, but it isn’t algorithmic either; it requires calibrated perception of context.

Subtext: he’s drawing a line between true virtue and performative righteousness. You can “do the right thing” for vanity, fear, or habit, and Aquinas would still call the soul bent. Rectitude is an inner straightness that makes outward right action reliable, not accidental. It’s also a political claim in theological clothing: societies don’t become just by stacking punishments and procedures; they become just by cultivating people capable of owing, discerning, and delivering what’s due under pressure.
