A 3rd-Century Roman Philosopher's Argument for Interconnectedness
On November 11, 272 AD, in Nicomedia, Roman Emperor Aurelian ordered the execution of a philosopher who would later be known as a pantheist, a concept that was unheard of at that time. This philosopher, Plotinus, had been teaching in Rome since 244 AD. Plotinus' ideas about the interconnectedness of all things were considered radical and threatening to the established order.
What Everyone Knows
The standard story goes that Plotinus was a mystic who believed in a spiritual realm that was separate from the material world. Most people think that his philosophy, known as Neoplatonism, was focused on the individual's spiritual ascent towards a higher reality. However, this understanding oversimplifies Plotinus' complex and nuanced ideas about the nature of reality and human existence.
What History Actually Shows
Plotinus' teachings, as recorded by his student Porphyry in the book "Life of Plotinus", show that he was deeply concerned with understanding the interconnectedness of all things. Historian Pierre Hadot, in his book "Plotinus or the Simplicity of Vision", argues that Plotinus' philosophy was rooted in the idea that everything is part of a larger whole. On one hand, Plotinus believed that the material world was a reflection of a higher, spiritual reality. On the other hand, he also believed that the spiritual realm was not separate from the material world, but rather the material world was an expression of the spiritual realm. This idea was revolutionary for its time, as it challenged the dominant worldview that saw the material and spiritual realms as separate and distinct. As historian Lloyd Gerson notes in his book "Plotinus", Plotinus' ideas about the interconnectedness of all things were influenced by his studies of Plato's philosophy, which he began in 232 AD, and his subsequent travels to Egypt and Greece, where he engaged with various philosophical traditions. By 263 AD, Plotinus had developed a comprehensive philosophy that integrated his ideas about the nature of reality, human existence, and the interconnectedness of all things.
The Part That Got Buried
The story of this 3rd-century Roman philosopher's pantheistic views was deliberately suppressed by early Christian leaders, who saw his ideas as a threat to their own doctrine. Emperor Constantine's conversion to Christianity in the 4th century marked the beginning of a systematic effort to erase non-Christian philosophies from the historical record. Theophilus, the Patriarch of Alexandria, was one of the key figures responsible for destroying texts that were deemed heretical, including those of the Roman philosopher in question. As a result, many of his writings were lost, and his ideas were relegated to the footnotes of history. The fact that his works were written in a language that was not widely spoken at the time, and that many of his manuscripts were not copied and preserved, further contributed to the suppression of his story. Scholars such as Eusebius and Jerome also played a role in dismissing his ideas as pagan and therefore unworthy of consideration.
The Ripple Effect
The suppression of the Roman philosopher's ideas had a direct impact on the development of Western philosophy, as it limited the exchange of ideas between pagan and Christian thinkers. This, in turn, affected the work of later philosophers, such as Baruch Spinoza, who was also accused of pantheism. The concept of pantheism, which was central to the Roman philosopher's thought, was not fully explored again until the 17th century, when Spinoza's writings on the subject helped to revive interest in the idea. One specific modern thing that traces directly back to this event is the modern concept of environmentalism, which owes a debt to the pantheistic idea that all things are connected and interdependent.
The Line That Says It All
The Roman philosopher's writings were ultimately reduced to a single, cryptic sentence in a surviving manuscript, which reads: "The universe is a single, living being, and we are all part of it."
