SAF is not an invention. Nearly all of it is inherited, and I would rather be precise about which parts than vague about all of them.
This is the attribution piece: where each faculty came from, what I changed, and what the change cost. If you want the framework’s argument rather than its genealogy, that is here.
Where each faculty comes from
Intellect — Plato and Aristotle. They asked the first systematic questions about the mind and saw an internal struggle: the rational part against the appetites, what we know is right against what feels good. The Intellect as a distinct power of the soul, and character as something built rather than given, both start here.
Will — Augustine. This is the contribution people skip, and it is the one that answers an obvious objection. Augustine looked at a model with reason on one side and desire on the other and found a hole in it:
How can a person know what is right and still choose to do what is wrong?
If reason were enough, that could not happen. It happens constantly. So there must be a third, independent faculty — the power to choose which path to follow, separate from the power to see which path is better. Augustine called it the Will, and it is the reason SAFi has a Will at all rather than folding the decision into reasoning.
Values — Aquinas, under a different name. Aquinas uses synderesis for the habit that holds first principles without deliberating about them: the standard you do not re-argue every time you use it. That is exactly the role Values plays, and it is why the component that compiles them carries that name in the implementation. This is the oldest part of the framework and the part I contributed least to.
Conscience — Aquinas, but not as a faculty. Worth stating carefully, because it is easy to get wrong. For Aquinas conscience is not a separate power at all; it is an act of the intellect, the one reasoning faculty applying moral knowledge to a particular case. The tradition treated it as a function, not a member of the family.
Spirit — mine. The only genuinely new one, and even then the raw material is classical: virtue ethics already holds that character is built by habit, by repetition. What I added is its role as the integrator of the whole loop.
What I changed, and what it cost
Two changes, and one of them was a trade.
For 1,500 years these faculties were discussed independently rather than as a sequence. I put them in a specific order — Intellect → Will → Conscience — and that meant deciding where conscience sits.
I struggled with it. In a person, conscience is both proactive and reactive: it warns you before you act, and it nags you afterwards when you have gone against your values. It is a feedback system, and we experience it through emotion rather than through argument.
Eventually I placed it after the Will, as the judge of actions already proposed. I want to be plain about the consequence: this degraded the function of the conscience. It gave up the warning-beforehand half in exchange for a loop that is systematic and testable. That is a real loss, accepted deliberately, and anyone who tells you a design has no costs is selling something.
The second change was adding the Spirit. Once the order was settled the flow was clear — the Intellect proposes, the Will decides, the Conscience judges — but nothing captured performance over time. Character, in the classical account, is precisely what accumulates. So the Spirit tracks long-term coherence and measures how far the system has moved from what it has been.
Why it is called Spirit
I debated this for a long time. The word is abstract and loaded with metaphysical weight, and I could not find a better one.
Spirit is the manifestation of alignment, or of its absence. When a person’s values and actions harmonise, something emerges that we recognise as meaning. Reading scripture I kept finding passages that alluded to it — the blessed mother’s praise in Luke 1:47:
“My soul magnifies the Lord, and my spirit rejoices in God my Savior.”
For me that describes a spirit in perfect alignment. Nothing in SAFi claims to produce that; the faculty is named after the thing it is trying to measure.
Five members, four inherited
The family tree, then: Values, Intellect, Will, Conscience, Spirit. Four of the five come down from the tradition — two from Greece, two from Augustine and Aquinas. One is mine, and one arrangement is mine.
That is a smaller contribution than a new framework and a more defensible one. If the parts have held up for two thousand years, the useful question is not whether they are right but whether they can be made to operate — which is what SAFi is for.
