What Ifá is, how the divination actually works step by step, how the binary structure produces 256 addresses into a memorised corpus, and what is true and false in the claim that it is an ancient computer.
The Yorùbá wey dem quote, the proverbs, oríkì, ẹsẹ Ifá, word list headwords, Odù names and citations dey exactly as the corpus record dem, for every language.
Ifá na one Yorùbá divination system and di full body of knowledge wey dey under am. One trained priest dey do one random process wey go bring out one of 256 signs, each sign na address for one large collection of cram verses, and di priest go dey recite from dat collection until something fit di client situation, come explain am and usually tell wetin dem go give for sacrifice. UNESCO, wey put Ifá inside Representative List of the Intangible Cultural Heritage of Humanity for 2008, describe am say e dey use "an extensive corpus of texts and mathematical formulas" and talk straight say e "does not rely on a person having oracular powers but rather on a system of signs that are interpreted by a diviner"
Dat last sentence na di main point to hold. Di diviner no be psychic or person wey dey see vision. Di diviner na person wey cram one massive indexed corpus and wey dey run random search inside am.
Ọ̀rúnmìlà na di òrìṣà wey join body with Ifá. For di tradition own story, e dey present when human beings dey choose dia destiny before birth, and so e know wetin dem choose; na why dem fit ask am about person situation. Dem dey also use Ifá as name for Ọ̀rúnmìlà and for di system itself, and di mix-up dey inside di Yorùbá.
Èṣù na must. Nothing wey dem offer go reach destination unless Èṣù carry am, and di start of consultation dey recognize am. E no be devil and devil no dey inside di system; na nineteenth-century Bible translation bring dat idea, and dem document am for di foundations section.
Di babaláwo, wey mean father of the secret word for word, na di diviner. UNESCO translate di title as "the priest's father" Di matching title for women inside Ifá na ìyánífá.
Di Odù na di 256 signs. Each one na binary figure and each one na address for one body of verse.
Di ẹsẹ na di verses. UNESCO put am say dem reach roughly eight hundred per Odù and talk say nobody know di exact total because e dey always increase . Make una take di calculation simple: na collection wey dey inside hundreds of thousands of verses, wey dem keep for memory without writing.
Di tools. Di ọ̀pẹ̀lẹ̀ na divination chain wey get eight half-seeds. Di ikin na sixteen sacred palm nuts. Di ọpọ́n Ifá na carved wooden tray for divination, and ìyẹ̀rosùn na di fine powder wey dem spread on top am wey dem dey draw marks inside.
Na this feature dey surprise people pass and e dey very central to how di system dey work. Di client no dey tell di babaláwo wetin make am come. For normal practice di client go hold coin or another object, whisper or think di question for mind, and di divination go proceed without telling di diviner. Di system dey designed so dat wetin di diviner know about di client situation no go be input at all.
Two methods dey and dem dey produce di same kind of result.
With di ọ̀pẹ̀lẹ̀. Di chain get eight half-seeds, four for each side of one middle link. Di babaláwo dey hold am for middle, let di halves hang, and throw am down on top di tray or mat . Each half dey land in one of two ways: di hollow surface face up or di hollow surface face down. Shell wey di hollow surface face up dey get single mark, hollow surface wey face down dey get double mark . Di four for one side dey give di first half of di figure, di four for di other side dey give di second half, and trained priest dey read di full figure at once . One throw, one complete Odù.
With di ikin. E slow pass, older and dem take am as di more serious method. Di sixteen palm nuts dey for one hand and di babaláwo go grab dem with di other hand, with aim to carry everything comot except one or two. If two nuts remain for di first hand, e go make single mark inside di ìyẹ̀rosùn on top di tray; if na one nut remain, e go make double mark . Any other number na void result and e go repeat di grab . Take note of di reverse, wey person mind fit no quick go: two wey remain dey give one mark, one wey remain dey give two marks. To repeat this four times go give one of di sixteen basic figures; to repeat am eight times go give one pair, wey be one of di 256 . Eight valid results fit take pass eight attempts well well . Dem dey leave di marks inside two columns of four, right column first .
Di result na figure inside two columns of four positions each. Every position na either single mark or double mark. Na di full notation be dat.
Four positions, two states each, dey give sixteen possible half-figures. Dis sixteen na di principal Odù, wey dem know as di Ojú Odù, and dem get names and fixed order of seniority wey di diviner must know: Èjì Ogbè, Ọ̀yẹ̀kú, Ìwòrì, Òdí, Ìrosùn, Ọ̀wọ́nrín, Ọ̀bàrà, Ọ̀kànràn, Ògúndá, Ọ̀sá, Ìká, Òtúrúpọ̀n, Òtúrá, Ìrẹtẹ̀, Òṣé and Òfún . When both columns show di same figure di Odù na méjì, wey mean doubled one, and dis sixteen doubled Odù na di senior ones. When di columns different, di combination na one of di remaining 240.
Sixteen possibilities for di left column and sixteen for di right dey give 16 × 16 = 256, wey Wikipedia summary write as "a collection of sixteen, each of which has sixteen alternatives ⇔ 16², or 4⁴"
Once dem identify di Odù, di babaláwo go start to recite ẹsẹ wey belong to am. E no know which one apply. E go recite, and di client go show say e relate to am, or di diviner go narrow am down with more throws using ibò, small objects wey client dey hold for hand to give yes-or-no binary answers to questions wey di diviner ask.
Di verses dem get dia own special shape. Most of dem na past case: dem consult Ifá for one named person, wey dey go somewhere or want something; dem tell am make e do one particular sacrifice; e do am, or e no do am; and na di result be this. Di verse dey come with story wey already attach to am, and di work of interpretation na to connect dat story with di client situation wey dem never talk out.
Normal normal, di verse dey prescribe ẹbọ, wey be offering: kolanut, red oil, water, cooked food, cloth, money, sometimes fowl or goat. Plenti times e dey prescribe behavior join, and beta part of ẹsẹ dey prescribe say make person change character instead of to just bring material sacrifice, based on di corpus own principle say ìwà, wey be character, matter pass sacrifice.
Dis na di part wey readers wey come for information system go want, and e make sense to treat am carefully because both di people wey dey wave am comot and di ones wey dey exaggerate am, all of dem dey wrong.
Binary sign system. Eight positions, each one dey resolve to one of two states, wey physical randomising device dey produce. Dat one na exactly binary word wey its length na eight. For modern notation, if we write 0 for single mark and 1 for double mark, Odù na eight-bit string, and di number of different eight-bit strings na 2⁸ = 256.
Positional structure, no be tally mark. Di positions get order and di order dey matter. No be how many mark dey inside dey distinguish Èjì Ogbè and Ọ̀yẹ̀kú Méjì, na which position carry which mark. Na dis make am place-value sign system instead of counting system, and na dis part people no dey quick notice.
Addressing. Di 256 signs no be di answer. Na address of di answer dem be. Each Odù dey point to body of verse wey dey somewhere else, inside di diviner memory, and wetin di divination dey do na to retrieve information, no be to compute am. Dis na exactly di structure of indexed lookup: one key, wey clear procedure generate, wey dey point to stored record.
Ranking. Di Odù get fixed order of seniority, wey mean say di 256 addresses no just be set wey scatter, na ordered set dem be, and dat order carry information wey dem dey use for interpretation.
Scale. Di corpus wey dem index reach hundreds of thousands of verses, according to UNESCO estimate roughly eight hundred per Odù, and nobody really know di total finish as e dey increase . All of am dey inside memory, spread across group of priests, and dem dey pass am down through apprenticeship for years.
Deliberate randomisation. Dem design di system so dat nobody fit control di input, and di ikin procedure dey troway results wey fall outside di valid range instead of to accept dem. Dat one na rejection-sampling rule, and di reason na to keep di key generation clean.
Ron Eglash book African Fractals (1999) treat Ifá as one of di indigenous mathematical systems wey develop pass, and e identify combinatorial reasoning inside am many centuries before Europe formalise dat same reasoning . Olu Longe analysis identify binary representation, Boolean algebra and memory addressing inside di system . Formal algebraic characterisations of di Ifá codes don dey published inside mathematical literature . UNESCO own description point to di mathematical formulas of di system . Di most careful recent framing describe Ifá as decision-support system wey dem map coded output to narrative data and trained practitioner go interpret am, and e summarize di point say "E no be mystical thing, na algorithmic"
Say na Ifá cause, influence, or be di origin of modern computing.
Eglash propose transmission lineage wey flow from African divination pass through Arab geomancy and European alchemy reach Leibniz, but di evidence for dat particular chain weak . Historians of mathematics wey dey work directly on Leibniz binary system don examine di external influences wey people propose and dem no find any candidate wey plausible, as manuscript evidence show say Leibniz no look alternative number systems before e develop binary, na why academic question don shift from who e get am from to why e invent am . Di careful writers wey dey make di Ifá-as-binary case no claim anything pass dat; di LSE work dey argue for recognition inside wider history of knowledge and make dem take Ifá as alternative model for system design, and e clear say dem no make any origin claim about computing .
Lineage question also dey wey need honest talk. Ifá belong to family of West African and North African divination systems wey get related binary structure, including Fá among Fon people, Afá among Ewe people, sixteen-cowrie divination, and di geomantic systems of di Arab world and medieval Europe. Which direction influence flow, and how much e reach, na matter wey still open. Di Ifá corpus na di biggest and most elaborate member of dat family with wide margin, wey be strong point on its own and e no need claim say na im first start am before e go make sense.
"One West African oral tradition develop formal binary sign system on its own, use am as addressing scheme for corpus of several hundred thousand verses, keep everything for human memory, and pass am down through apprenticeship for centuries" na statement wey remarkable and person fit defend am. "Na Ifá invent computer" no be any of di two, and to claim am dey invite counter-argument wey go pull down di true statement join body. Di interesting question no be whether Ifá anticipate binary arithmetic; na which problem di binary structure dey solve, and di answer na real problem for information design: how to build stable, memorable, unbiased index put inside body of knowledge wey big pass wetin person fit search one by one, without writing anything down.
Three ways to understand Ifá dey circulate, and dem no dey cancel each other.
As religion. Ọ̀rúnmìlà witness when dem choose destiny and person fit consult am about am, di òrìṣà dey real, ẹbọ dey work, and di divination dey reveal something wey be true about di client situation and wetin di person suppose do. Na so di tradition explain itself and na wetin practitioners hold.
As knowledge system. Di corpus na storehouse. Di verses carry medical knowledge, plant knowledge, historical precedent, genealogy, social rules, ethical argument, and law, wey dem arrange under one system wey person wey get training fit search. Under dis kind understanding, di divination na di interface and di corpus na di main point.
As decision procedure. Person wey want make decision dey receive one story from past wey dem pick through process wey pass dem control, and dem must figure out how dat story match dia own case. Dat kind structure dey cut overthinking, e dey force person to clearly state wetin be di actual problem, e dey bring gathered judgment from past come apply to di matter, and e dey bring out wetin person suppose do. Whether person accept di metaphysics or not, na so di procedure dey work for person wey dey pass through am.
Reader wey come from Christian or Muslim background fit hold di second and third understanding without holding di first one, and plenty scholars wey don document Ifá with care dey do exactly dat.
Ifá na system wey get levels of initiation, and plenty of wetin dey inside am no dey published. Di training of babaláwo dey take years, dem dey learn di Odù step by step, dem dey pass particular material across for particular stages, and dem no dey repeat some of dem outside grove. Wetin dem write for up na di structure wey public fit confirm. No be di complete system, and any source wey claim say e dey give you di whole system inside book dey show you di kind source wey e be.
