Iamblichus was a highly influential Syrian Arab Neoplatonist philosopher. He lived during the late third and early fourth centuries. His work helped determine the future direction of Neoplatonism. He was also a noted biographer of the mathematician Pythagoras. Beyond his own theories, he helped preserve ancient knowledge. His writings saved about ten pages of work by a sophist known as the Anonymus Iamblichi.

Iamblichus was born in Chalcis, which is now called Qinnašrīn. This area is in northwest Syria. He came from a wealthy and well-known family. His family was part of the Emesene dynasty. He began his education under Anatolius of Laodicea. Later, he studied with Porphyry. Porphyry was a student of Plotinus, the founder of Neoplatonism. Iamblichus and Porphyry had different views on theurgy. Theurgy is a type of divine practice. Iamblichus wrote a response to Porphyry's criticisms of these practices.

Around the year 304, Iamblichus returned to Coele Syria. He founded a philosophical school in the city of Apamea. This city was already famous for its Neoplatonic thinkers. He created a specific curriculum for studying Plato and Aristotle. He also wrote commentaries on their works. Most of these writings survive only as small fragments. Iamblichus viewed Pythagoras as his supreme authority. He wrote a ten-volume work called the Collection of Pythagorean Doctrines. Only the first four volumes and parts of the fifth volume remain today.

His philosophical system was very detailed and complex. He used Pythagorean number symbolism in a systematic way. He also interpreted Neoplatonic concepts through a mythical lens. Iamblichus had a different view of the soul than Plotinus. Plotinus believed the soul was separate from the physical world. Iamblichus argued that the soul is embodied in matter. He believed that matter was as divine as the rest of the cosmos. This idea changed how his followers viewed the physical universe.

In his cosmology, Iamblichus placed the Monad at the very top. The Monad is the single source of all things. From the Monad, the Nous and the psyche emanate. The Nous is the intellect or the demiurge. Plotinus saw the Nous in three specific stages. Iamblichus divided the Nous into two different spheres. These are the intelligible sphere and the intellective sphere. The intelligible sphere contains the objects of thought. The intellective sphere is the actual domain of thought.

Iamblichus also developed a complex system of divine beings. He used mathematical theorems to multiply these entities. He identified twelve heavenly gods in his system. This number could increase to 36 or even 360. He also described 72 other gods. His hierarchy included 21 chiefs and 42 nature-gods. These beings include gods, angels, demons, and heroes. These superhuman beings can influence natural events. They can also communicate knowledge about the future through prayers and offerings.

His ideas had a lasting impact on later history. The identification of the Nous with the demiurge influenced Christian gnosticism. The thinker Augustine of Hippo followed Plotinus's lead. Augustine identified the Nous with the logos. The logos is a creative principle within the Trinity. Iamblichus also believed that numbers were independent entities. He placed numbers in a middle realm between the limited and the unlimited. He believed that nature is bound by fate. However, divine things are not subject to fate.

Many historical figures admired the learning of Iamblichus. The Roman emperor Julian held him in very high regard. Julian believed Iamblichus was second only to Plato. He even said he would trade all the gold in Lydia for one letter from him. During the 15th and 16th centuries, interest in his work grew again. During this revival, people often called him "divine" or "most divine." Today, scholars still study his fragments to understand ancient philosophy.
