The higher, widely used academic dataset estimate: the Correlates of War Project's own coded battle death totals record approximately 500,000 Iraqi and 750,000 Iranian dead, a combined 1,250,000. The two named estimates reflect different methods, government-and-paramilitary tallying against a standardized cross-national coding scheme, rather than a single disputed number.

Concerns Death Toll Assessment

Currently States Two independently derived figures are recorded rather than one disputed number: sociologist Charles Kurzman's demographically skeptical check of the Iraqi and Iranian governments' own casualty claims against each country's 1990s census data, roughly 405,000 combined, as the lower bound; and the Correlates of War Project's standardized cross-national battle-death coding, about 1,250,000 combined, as the higher, methodologically different estimate. The war's religious framing is itself a live historiographic question: Saddam Hussein's Iraq fought the war primarily over territorial and Arab-nationalist grievance (the Shatt al-Arab waterway, Khuzestan), not confessional difference, even though Iran's post-revolutionary Shia Islamist government and Iraq's Sunni-led Ba'athist state gave the war a Sunni-Shia coloring that later sectarian historiography has sometimes read back into the conflict's own causation more strongly than the belligerents' own stated war aims support.

Concerns Origin Period

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.

Concerns Death Toll Minimum

Currently States 400000.000000

William Petty's 1650s Down Survey, the era's only systematic contemporary count, put total deaths from war, famine and plague across 1641 to 1652 at not less than four hundred thousand. Lenihan and other modern historians still cite this as the traditional low bound even while treating Petty's own method, extrapolating from incomplete surveys and never separating war deaths from famine and plague mortality, as unreliable for a precise total.

Petty's own upper estimate reached six hundred and twenty thousand, as much as two fifths of Ireland's pre-war population by some readings. Lenihan's own demographic scholarship, in his article "War and Population, 1649 to 52," argues this upper figure in particular overstates war-caused mortality, and no modern historian has produced a rival reconciled total that separates combat and massacre deaths from the era's simultaneous famine and plague.

Concerns Religious Dimension

Currently States The Confederation bound its members by the Oath of Association, a specifically religious oath to defend the public and free exercise of the Catholic religion alongside the king's prerogative, and Catholic clergy sat as full members of its General Assembly; the papal nuncio Rinuccini's presence and his demand for full Catholic religious establishment as a condition of peace, which split the Confederation from within, underscore how far religion structured the conflict on the Catholic side. O Siochru's constitutional study nonetheless stresses the Confederation was never a simple Catholic crusade: its moderate faction, led by Nicholas Plunkett, was consistently willing to trade religious toleration for political accommodation with the Protestant royalist Ormond, and dynastic loyalty to Charles I and Old English constitutional grievance ran alongside religious motive throughout.

Irshya (Envy), Vices

Concerns Origin Period

Currently States Irshya, called issa in the Pali Abhidhamma where it is treated only as a secondary mental factor, becomes the fifth of the five poisons and is read within the five Buddha family scheme as the distortion of the wisdom that accomplishes all actions only in the later, more elaborate systematisation. John Powers's Introduction to Tibetan Buddhism (Snow Lion Publications, 2007) locates that five-poison, five-Buddha-family systematisation chiefly in Tibetan scholastic and tantric literature, later than the Pali material's earlier and more modest treatment of issa.

Lester L. Grabbe's Ancient Israel: What Do We Know and How Do We Know It? (2007) examines the patriarchal narratives against the archaeological and textual record for the second millennium BCE and finds no extra-biblical evidence for Isaac, and that the patriarchal narratives generally cannot be securely placed in any second-millennium setting. Judaism, Christianity and Islam nonetheless hold him to be a historical patriarch, the son of promise through whom Abraham's covenant passed to Jacob.

Concerns Mythic Association

Currently States The Genesis account of the Binding of Isaac, in which Abraham nearly sacrifices him at God's command before a ram is substituted, names him as the son involved, though Islamic tradition more commonly identifies the son as Ishmael.

The rabbinic and Christian tradition, following Genesis 22, names Isaac as the son bound for sacrifice at Moriah; the Quran does not name the son at all, and while a minority of early Muslim exegetes read the unnamed son as Isaac, the majority position, and the modern popular consensus among Muslims, holds it was Ishmael, reflecting a genuine, unresolved divergence in how the three Abrahamic traditions each claim their own founding covenant narrative for their own patriarch.

Affirmed within Christian tradition since the New Testament itself.

Ishvara Pranidhana (Devotion to the Divine), Virtues

Standing Scholarly debate

Concerns Origin Period

Currently States Dated by scholars anywhere from the second century BCE to as late as the fourth or fifth century CE, the same span debated for the Yoga Sutras as a whole: an early dating follows the tradition's own attribution to a single ancient sage, while a late dating, argued by scholars such as Philipp Maas, reads the surviving text as a composite assembled together with its own earliest commentary.

The Yoga Sutras' date is disputed among scholars, from a single ancient author around the second century BCE to a later compilation as late as the fourth or fifth century CE; the debate turns on whether the text and its earliest surviving commentary were composed together or centuries apart.
