Axial Age

Axial Age (also Axis Age, from the German Achsenzeit) is a term coined by the German philosopher Karl Jaspers. It refers to broad changes in religious and philosophical thought that occurred in a variety of locations from about the 8th to the 3rd century BCE.

According to Jaspers, during this period, universalizing modes of thought appeared in Persia, India, China, the Levant, and the Greco-Roman world, in a striking parallel development, without any obvious admixture between these disparate cultures. Jaspers identified key thinkers from this age who had a profound influence on future philosophies and religions and pinpointed characteristics common to each area from which those thinkers emerged.

The historical validity of the Axial Age is disputed. Some criticisms of Jaspers include the lack of a demonstrable common denominator between the intellectual developments that are supposed to have emerged in unison across ancient Greece, the Levant, India, and China; lack of any radical discontinuity with "preaxial" and "postaxial" periods; and exclusion of pivotal figures that do not fit the definition (for example, Jesus, Muhammad, and Akhenaten).

Despite these criticisms, the Axial Age continues to be an influential idea, with many scholars accepting that profound changes in religious and philosophical discourse did indeed take place but disagreeing as to the underlying reasons. To quote Robert Bellah and Hans Joas, "The notion that in significant parts of Eurasia the middle centuries of the first millennium BCE mark a significant transition in human cultural history, and that this period can be referred to as the Axial Age, has become widely, but not universally, accepted."

Jaspers introduced the concept of an Axial Age in his book Vom Ursprung und Ziel der Geschichte (The Origin and Goal of History), published in 1949. The simultaneous appearance of thinkers and philosophers in different areas of the world had been remarked by numerous authors since the 18th century, notably by the French Indologist Abraham Hyacinthe Anquetil-Duperron. Jaspers explicitly cited some of these authors, including Victor von Strauß (1859) and Ernst von Lasaulx (1870). He was unaware of the first fully nuanced theory from 1873 by John Stuart Stuart-Glennie, forgotten by Jaspers' time, and which Stuart-Glennie termed "the moral revolution". Stuart-Glennie and Jaspers both claimed that the Axial Age should be viewed as an objective empirical fact of history, independently of religious considerations. Jaspers argued that during the Axial Age, "the spiritual foundations of humanity were laid simultaneously and independently in China, India, Persia, Judea, and Greece. And these are the foundations upon which humanity still subsists today."

Jaspers identified a number of key thinkers as having had a profound influence on future philosophies and religions, and identified characteristics common to each area from which those thinkers emerged. Jaspers held up this age as unique and one to which the rest of the history of human thought might be compared.

Jaspers presented his first outline of the Axial age by a series of examples:

Confucius and Lao-Tse were living in China, all the schools of Chinese philosophy came into being, including those of Mo Ti, Chuang Tse, Lieh Tzu and a host of others; India produced the Upanishads and Buddha and, like China, ran the whole gamut of philosophical possibilities down to materialism, scepticism and nihilism; in Iran, Zarathustra taught a challenging view of the world as a struggle between good and evil; in Ancient Israel the prophets made their appearance from Elijah by way of Isaiah and Jeremiah to Deutero-Isaiah; Greece witnessed the appearance of Homer, of the philosophers—Parmenides, Heraclitus and Plato—of the tragedians, of Thucydides and Archimedes. Everything implied by these names developed during these few centuries almost simultaneously in China, India and the West.
