Concerns Legal Status

Currently States The constitution declares the state secular and guarantees freedom of religion; religious associations register with the Ministry of the Interior, and religious identity was central to the citizenship disputes underlying the 2002 to 2011 conflicts.

Ivory Coast's constitution declares the state secular and guarantees freedom of religion, with religious associations registering administratively through the Ministry of the Interior rather than through any religion-specific legal process. The State Department's report records that religious identity, closely correlated in Ivory Coast with regional origin and with the contested concept of Ivoirite, or authentic Ivorian national belonging, was central to the citizenship disputes that underlay the country's civil conflicts from 2002 to 2011, in which predominantly Muslim northerners, often of recent or contested immigrant descent, were pitted against a predominantly Christian and animist south over who qualified as a full citizen. The dispute here is less over the constitution's secular text, which is not itself contested, than over whether that formal secularism actually governed how citizenship and political eligibility were adjudicated during the conflict period. Whether the underlying belonging questions have been durably resolved since remains a matter of ongoing Ivorian politics.

Concerns Approximate Gregorian Span

Currently States Early to late January

Scholars have proposed several correlations between the xiuhpohualli year and the Gregorian calendar. The month range given here follows one widely reproduced reconstruction and is offered for relative placement only, not as a settled date: the 365 day count carried no intercalated leap day, so its alignment with the solar year is understood to have drifted across the centuries of its use, and colonial era testimony was recorded decades after the practice had ended.

Izon (Ijo), Languages

Standing Scholarly debate

Concerns Language Family

Currently States The largest of the Ijoid languages. Ijoid is conventionally placed within Niger-Congo but stands apart from every other branch of it.

Standard reference works classify Ijoid within Niger-Congo. A minority of specialists hold that the shared vocabulary is too sparse and the basic word order too divergent for the relationship to be demonstrated, and treat Ijoid as unclassified or as an isolate branch. The atlas records the conventional placement together with the objection to it rather than choosing between them.

Concerns Chaldean Letter Value

Currently States 1

According To Modern planetary numerology, the scheme called Chaldean

The values recorded here follow Cheiro's Book of Numbers (Cheiro, the pen name of William John Warner, published by Herbert Jenkins, London, 1926), the most widely reproduced version of the so-called Chaldean numerology table. Cheiro's own text names no ancient Chaldean source for the letter values it assigns, and comparing it against other published numerology tables from the same and later periods finds no agreement between them on several letters; no Mesopotamian or Chaldean text has ever been produced that contains a comparable letter-number correspondence. That comparison is why historians of the modern occult treat "Chaldean" as a nineteenth and twentieth century marketing label rather than a checkable lineage claim. The value recorded here is Cheiro's published reading, not a settled fact.

Concerns Principal Critic

Currently States C. E. M. Hansel, who reconstructed the physical settings of the Duke experiments and argued that ordinary sensory routes had not been closed off; Rhine and Pratt published detailed rejections of the reconstructions

Terence Hines's Pseudoscience and the Paranormal (Prometheus Books, 2003) surveys C. E. M. Hansel's architectural reconstructions of the Duke University buildings used in Rhine and Pratt's ESP experiments, offered as evidence that an ordinary sensory route between experimenter and subject was physically available and undetected by the original protocol. Hines's method is to compare Hansel's floor-plan-based reconstructions against Rhine and Pratt's own published accounts of the room layout, and finds the two sides' reconstructions dispute each other in physical detail, room dimensions, sightlines and what could plausibly be seen or heard through a shared wall, with neither the original investigators nor their critic conceding the other's version of the building.

Concerns Key Experiment

Currently States The Pearce-Pratt distance series of 1933 and 1934 at Duke, in which Pratt turned the cards in one building while Hubert Pearce recorded his calls in another

J. B. Rhine and J. G. Pratt's own published account of the Pearce-Pratt series (Journal of Parapsychology, 1954) reports the above-chance card-guessing results as the investigators recorded and scored them at the time, using a sealed, randomised deck and simultaneous timed recording in separate buildings. That reported result is accepted as accurately transcribed by later critics, but disputed as evidence of anomalous perception by those, following Hansel's architectural analysis, who argue the specific building layout used in the trials left an ordinary sensory route open that the protocol did not control for.

Concerns Principal Critic

Currently States C. E. M. Hansel, whose 1966 reconstruction of the Duke buildings proposed a route by which the subject could have observed the target cards

C. E. M. Hansel's ESP: A Scientific Evaluation (Charles Scribner's Sons, 1966) presented Hansel's own on-site architectural investigation of the Duke University buildings used in the Pearce-Pratt series, arguing the physical layout permitted an ordinary sensory or signalling channel the original 1930s protocol had not excluded. Rhine and Pratt rejected Hansel's reconstruction of the buildings in print, disputing his description of the rooms and sightlines involved, and the disagreement, which turns entirely on the physical architecture of two specific rooms decades after the trials took place, was never independently resolved by a third party inspection.

Concerns Place of Origin

Currently States Traditional Islamic bio-bibliography (Ibn al-Nadim) names Tus, in Khorasan, with other medieval accounts instead naming Kufa, in Iraq. Scholarship associated with Paul Kraus holds that much of the corpus attributed to him is the work of a school active into the ninth and tenth centuries, which would mean no single birthplace applies at all.

Jabriyya, Doctrines

Standing Scholarly debate

Concerns Held By

Currently States An early eighth century position, most closely associated with Jahm ibn Safwan, holding that God is the sole and direct cause of every human act and that human beings possess no real power of their own to choose or cause their actions; not held by any major Sunni school in this full form today, though later Ashari theology retained a strong emphasis on divine decree while rejecting the position complete determinism.

Watt notes the label Jabriyya was applied broadly by opponents to several distinct positions on divine determination, not only to Jahm ibn Safwan own teaching, so the boundary of what belongs to the school is itself debated among historians.

(2007) finds no extra-biblical evidence for Jacob on the same second-millennium documentary record examined for the other patriarchs, and that the patriarchal narratives cannot be securely placed in any specific second-millennium setting. Judaism, Christianity and Islam hold him to be a historical patriarch, father of the twelve tribes and namesake of Israel.

Jaijawanti, Scripture Portions

Standing Scholarly debate

Concerns Point in Dispute

Currently States Whether the Ragmala, the verse listing of rags that stands at the very end of the volume after the rag sections close, is part of the Guru Granth Sahib

One position holds the Ragmala to be an integral part of the scripture, present in the Kartarpur manuscript and printed in every standard copy, and reads it accordingly. Another holds it to be a scribal addition rather than the word of the Gurus, and some congregations do not recite it when completing a reading of the volume. The question has been argued within the Panth since the nineteenth century and is not settled.

Concerns Historicity

Currently States Historicity debated

Jaimini is the name tradition attaches to the Mimamsa Sutra, but no external record fixes when he lived. The Mahabharata places him as a direct disciple of the sage Vyasa, a legendary genealogical framing rather than an independent historical record, and the Mimamsa Sutra's own composition is dated on textual grounds to between the fourth and second century BCE, a dating of the text rather than of the person its name is attached to. The Stanford Encyclopedia of Philosophy (2024) treats the sutra's date and the author's biography as separate and differently evidenced questions, which is why historicity here is carried as debated rather than as a settled life.

Currently States Sikh tradition credits Guru Angad, the second Guru, with giving the script its settled form in the sixteenth century

According To The Gurmukhi script

Two reference works give incompatible accounts. The Encyclopaedia of Sikhism (Harbans Singh, editor-in-chief, Punjabi University, Patiala, 1998) carries the Sikh tradition that Guru Angad, the second Guru (1504-1552), devised the script. The World's Writing Systems (Peter T. Daniels and William Bright, eds., Oxford University Press, 1996), surveying the paleography of Indic scripts, holds instead that the letterforms were already in mercantile use in the Punjab as one of the Landa scripts descended from Sharada, and that comparing those existing Landa forms against the Gurmukhi letters attested from Guru Angad's era shows a fixing and standardising of a repertoire already in circulation rather than an invention from nothing. Neither side has displaced the other because the two accounts read different kinds of evidence, a community's own historical memory against a comparative script lineage, and the atlas records both without adjudicating.
