Ifá: Section Index

Ifá is a Yorùbá divination system, a corpus of orally transmitted verse running to an estimated hundred thousand poems or more, a repository of medical, historical and ethical knowledge, and a profession with a training pathway of two decades. This section covers all four. It describes the system as scholarship documents it and is not a manual: it contains no instructions for performing divination or ritual, and where the published record stops because knowledge is held by initiates, the files say so and mark confidence accordingly.

Concepts belonging to Yorùbá cosmology, Olódùmarè, orí, àṣẹ, ìwà, destiny, Èṣù and ẹbọ, are referenced throughout and treated in 04-cosmology.

The files

01. What Ifá Is. Ifá as divination system, literary corpus, body of knowledge and profession; Ọ̀rúnmìlà and the Ifá relationship; and why "fortune telling" misdescribes the mechanism, the content, the professional structure and the epistemology all at once.

02. The Binary Structure. Two columns of four positions, each single or double, giving four bits per column and 256 Odù; the mark conventions, the orientation rule, a worked example from cast to signature, and a precise statement of what the binary structure does and does not license.

03. The 256 Odù. Complete reference table of all 256 with signatures, the sixteen principal Odù in the competing ranking orders, the naming conventions, and the documented disagreement between lineages, regions and traditions about the order.

04. Ẹsẹ Ifá: The Verses. The eight-part verse structure with four obligatory parts and four free, how many verses exist, how the corpus is held collectively rather than by any individual, and several verses in full three-layer translation with commentary.

05. The Divination Procedure. Ikin, ọ̀pẹ̀lẹ̀, ọpọ́n Ifá, iyèròsùn, ìróké, ìbò and the rest; the sequence of a consultation from the whispered question to the prescribed offering; and the division between what the diviner decides and what he does not.

06. Becoming a Babaláwo. The decade or more of memorisation, the stages of training and initiation, professional ethics, how practitioners verify each other, and the genuine scholarly and community disagreement about women in Ifá.

07. Ifá as an Information and Memory System. The mathematics, the mnemonic architecture, what Eglash actually documented and about which system, and a point-by-point correction of the Leibniz claim and the other popular overclaims.

08. The Divination Family. Ẹẹ́rìndínlógún, obì, agbigba, Fọ̀n Fa, Ewe Afa, the Cuban and Brazilian systems, and Bascom's argument for why formal resemblance between divination systems proves much less than it appears to.

09. Ifá and Other Knowledge Domains. Herbal medicine, ethics as reasoning from cases, the corpus as historical source, and how far the comparison between ẹsẹ Ifá and case law holds before it breaks.

10. Ifá Today. The 2005 proclamation and 2008 UNESCO inscription, the practitioner community in Nigeria and the diaspora, digital and commercialised divination, Christian and Muslim pressure, and how a curious outsider should and should not approach the tradition.

11. Study Guide. Which books matter and which editions, what is legitimately available online, a reading order, and six practical tests for judging the unreliable material you will meet first.

On confidence

Files are marked high, medium or contested in their frontmatter, and the markers are used strictly. contested means the sources genuinely disagree or the published record is known to be partial, not that the material is doubtful. Three files carry it: file 03, because Bascom documented 21 alternative rankings of the sixteen Odù across 86 lists and no single order is universal; file 06, because the question of women's participation is disputed among scholars, among Nigerian practitioners, and between Nigerian and diaspora communities; and the initiate-restricted portions flagged within files 05 and 06.

Where the conflict is the information, the files show the conflict rather than resolving it.
