Becoming Superhuman || “The Art of Being Human” by al-Raghib al-Isfahani (Pt. 3)
A Deep Dive on “Tafṣīl al-Nashaʾatayn wa Taḥṣīl al-Saʿādatayn”
This is the companion Deep Dive to Episode 3 of my three-part YouTube series on al-Rāghib al-Iṣfahānī’s The Art of Being Human. Each episode gets its own deep dive: extended primary source translations, close readings, the philosophical architecture in full, and the material that couldn’t fit on camera.
All translations are based on the Dār al-Nafāʾis 1988 edition (ed. Asʿad al-Saḥmarānī).
Humanity, for al-Rāghib, has a finish line — and most of what the book has called “achievement” up to this point turns out to be incomplete without it. Part 2 told you what you’re built from and what you’re for. Part 3 tells you what happens when you actually do the work, what happens when you don’t, and why none of it would matter without something on the other side of death to redeem it.
The question this part of the book answers: If reason and revelation aren’t competing authorities but two faces of one cognitive apparatus, and if virtue and vice are both just habit calcifying into character — then what’s the ceiling on a human life, and what’s underneath it?
To answer it, al-Rāghib closes the system he opened in Part One. He explains why intellect and revelation need each other structurally, not just practically; he gives you a moral physiology of how a single repeated act becomes a rusted heart or an illuminated one; he tells you exactly how far your own effort can take you — and where it runs out; and he ends with a claim about death, and about what a human being can become, that makes the rest of the book look like throat-clearing. Along the way, he teaches us:
the “intellect from outside, revelation from inside” formula that shows how reason and revelation aren’t rivals for jurisdiction, they’re the same organ, externalized and internalized
a moral physics of habituation: how a single bad act produces, in sequence, a constriction of the breast, a film over the heart, a veil, a seal, a lock, and finally a dead heart that can no longer be reached — and the exact mirror-image sequence for good
a doctrine of grace that refuses two opposite heresies at once: you cannot purify yourself by effort alone, and you cannot expect purification without making the effort at all
death redescribed as a second birth and the book’s final claim that the human being, fully realized, outranks many of the angels
becoming “superhuman” by trading one’s vices for virtues so completely that animals obey them, iron softens for them, and fire turns cool around them.
This is the part of the book where al-Rāghib stops describing human nature and starts describing what it looks like fully realized — and the superhuman isn’t something beyond human, it’s human nature maxed out.
The question he leaves us with is the one the whole book has been building toward: are you actually human?
X. Reason and Revelation
This is the philosophical heart of the book, and al-Rāghib’s most sustained argument.
Know that the intellect (al-ʿaql) will not find guidance except through revelation (al-sharʿ), and revelation will not become clear except through the intellect. The intellect is like the foundation (al-us) and revelation is like the building (al-bināʾ): a foundation is of no use if there is no building, and a building will not stand if there is no foundation. Likewise, the intellect is like sight (al-baṣar) and revelation is like light (al-shuʿāʿ): sight is of no benefit if there is no ray coming from outside, and the ray is of no benefit if there is no sight.
And a third metaphor that is the most elegant:
The intellect is like a lamp (al-sirāj) and revelation is like the oil (al-zayt) that feeds it: if there is no oil the lamp does not come to be; and if there is no lamp the oil does not give light. God Most High said: “God is the light of the heavens and the earth. The likeness of His light is as a niche in which there is a lamp, the lamp in a glass, the glass as if it were a brilliant star, lit from a blessed tree — an olive, neither of the east nor of the west — whose oil would almost glow even if no fire touched it: light upon light. God guides to His light whom He wills.” (Q 24:35)
Then the formulation that cuts through the entire debate between rationalists and traditionists:
Revelation is an intellect from outside (ʿaql min khārij); the intellect is a revelation from inside (sharʿ min dākhil). The two support one another and are united.
This is not a compromise position. It is a structural claim. The intellect and revelation are not two separate authorities competing for jurisdiction. They are two aspects of a single cognitive and moral apparatus — one internalized, one externalized — and neither functions properly without the other.
On what the intellect can and cannot do:
The intellect (al-ʿaql) by itself has little power to avail. It hardly manages to reach more than knowledge of the generalities (kulliyyāt) of things, not their particulars — such as knowing in general the goodness of holding right belief, speaking truthfully, doing what is beautiful, practicing justice, keeping to chastity — without knowing how each of these applies in one concrete thing after another. Revelation makes known the generalities of things and also clarifies, in each particular matter, what exactly must be believed about it, and what exactly counts as the just mean. The intellect alone, for example, does not tell us that the flesh of the pig, blood, and wine are forbidden.
The five faces of revelation:
Know that, in one respect, the rulings of the revealed law (al-sharʿ) are like a finished medicine (dawāʾ) whose formulation has been undertaken by the One to whom belong creation and command — a medicine beneficial for eternal life and lasting safety. And in another respect it is purifying water (māʾ muṭahhir) that removes spiritual filth and inner defilements. And in another respect it is light (nūr) and a lamp (sirāj) that dispels darkness, bewilderment, and ignorance. And in another respect it is a means to God (wasīla). And in another respect it is the straight path (al-ṣirāṭ al-mustaqīm).
