Muqaddimah

The *Muqaddimah* is a foundational text in the study of human society.

Written by the historian Ibn Khaldun in 1377, the title is an Arabic word meaning "prologue" or "introduction." It was originally intended as the first part of a massive seventeen-volume work of universal history called the *Kitab al-ʿIbar*. However, the *Muqaddimah* became famous as an independent work. Modern thinkers often view it as one of the earliest studies of the social sciences. It covers many complex fields, including sociology, demography, and cultural history. It also explores economics, political theory, and ecology.

Ibn Khaldun developed a "new science" to study what he called *ʿumrān*, or civilization.

He wanted to move beyond simply recording events. He believed historians often made mistakes due to several critical issues. These included partisanship toward a specific creed or opinion. He also noted that historians often showed over-confidence in their sources. Other errors included a failure to understand the intended meaning of events. He observed that some writers sought to gain favor with powerful people through praise. Most importantly, he argued that many failed to understand the laws governing how human societies transform.

To fix these errors, Ibn Khaldun introduced a scientific method to the social sciences. This method was historical, empirical, rational, and demonstrative. He criticized the uncritical acceptance of historical data and idle superstition. Instead, he argued that history should be treated as a philosophical science. He believed historians must attempt to refute myths and interpret the past. He also emphasized the importance of recognizing systemic bias. This means understanding how a person's perspective might affect the evidence they accept. He argued that the cultural differences of an era must govern how we evaluate historical material.

One of his most significant contributions is the concept of *ʿasabiyyah*. This term refers to social cohesion, group feeling, or solidarity.

Ibn Khaldun used this concept to explain the cycles of history. He argued that strong *ʿasabiyyah* allows groups to build and maintain great empires. However, he believed that as dynasties become established, this social unity tends to decline. Rulers at the center of empires often become more concerned with their own lifestyles. As they become lax, a new group with stronger *ʿasabiyyah* may emerge from the periphery. This process creates a cycle where civilizations rise and then eventually fall.

Ibn Khaldun also provided early insights into economic theory. He introduced the labor theory of value, stating that labor is the source of all value. He argued that even when profit comes from something other than a craft, it must include the value of the labor used to obtain it. He also described how prices are determined by the laws of supply and demand. When a good is scarce and in demand, the price remains high. When a good is abundant, the price becomes low. He even connected social cohesion to the division of labor. He noted that greater social unity allows for a more complex division of labor, which stimulates economic growth.

His economic observations included what is now known as the Laffer curve. He argued that increasing tax rates can initially increase total tax revenue. However, if tax rates become too high, they eventually cause a decrease in total revenue. This happens because excessively high taxes discourage people from producing goods. He also noted that population growth is a function of wealth. He understood that money serves as a medium of exchange and a standard of value. These ideas link his work to modern concepts like supply-side economics and Keynesian economics.

The history of the *Muqaddimah* shows a slow journey toward global recognition. Ibn Khaldun wrote the first version while secluded in Qalʿat ibn Salama for nearly four years. In the centuries following its writing, the work received mixed reactions. Some contemporary writers in the Maghreb approved of it, while others in Egypt met it with hostility. Ottoman historians later valued his social and political theories. The work was first printed in Cairo in 1857. It was later translated into French and English. Scholars like Abdesselam Cheddadi note that his scientific contributions were not fully recognized in the Muslim world until the late nineteenth century.
