Critique of Historical Writing and Method

One of the most important sections of Al-Muqaddimah — placed programmatically at the very beginning — is Ibn Khaldun's devastating critique of earlier Islamic historical writing and his articulation of a new, more rigorous standard for historical methodology. This critique is as significant as his positive theoretical contributions and has become foundational for the philosophy of history.

Ibn Khaldun began by identifying the besetting failure of Islamic historians before him: the uncritical transmission of reports. Historians had traditionally included reports on the basis of the apparent reliability of their chain of transmitters (isnad), borrowed from hadith methodology, without asking whether the reported events were plausible given what we know about how human societies and power actually work. The result was a historical literature filled with exaggerated numbers, impossible claims, and internally inconsistent narratives.

His famous example was the traditional account of the army of Moses numbering 600,000 warriors — a figure Ibn Khaldun rejected not on the basis of chain criticism but on rational grounds: an army of that size could not have been fed, watered, or maneuvered in the Sinai Desert, and the administrative infrastructure required to organize such a force did not exist in the ancient world. The very implausibility of the number, regardless of the chain of transmission, should alert the historian.

This principle — what Ibn Khaldun called the criterion of possibility ('imkan) — represented a new standard in historical criticism. Reports should be evaluated not only on the basis of who transmitted them but on the basis of whether they are consistent with the known patterns of human social organization, economy, and power. A report that describes something impossible given those patterns should be rejected even if its chain of transmitters appears sound.

Ibn Khaldun's methodological critique also addressed bias (gharad) in historical writing — the tendency of historians to flatter powerful patrons, to take sides in factional disputes, and to present the history of their own group favorably. He recommended awareness of these distorting factors as part of a critical historical practice.
