Philosophy has long been a guiding tool for those seeking a more meaningful and fulfilling life. However, the sheer amount of information available on the subject can feel overwhelming and confusing for many. To truly benefit from philosophy, it is essential to return to its core principles, including the profound ideas of Pythagoras, particularly his concept of the immortality of the soul. Understanding this fundamental notion can deeply influence how we apply philosophy to live with greater purpose. This article examines Pythagoras’s teachings, explores the concept of the soul’s immortality, and highlights their importance in the philosophical quest for a more meaningful existence.
Key features of Pythagoras’s philosophy
Pythagoras’s philosophy is a blend of mathematics, mysticism, and a deep connection to the universe. He is best known for his contributions to mathematics, particularly the Pythagorean theorem, which links the sides of a right triangle. However, his ideas went far beyond numbers. Pythagoras believed that everything in the universe is interconnected and that numbers held the key to understanding this cosmic harmony. He viewed mathematics as a way to explain the order of the world, from the movement of the stars to the nature of musical harmony.
Pythagoras also emphasized the importance of the soul. He believed in the concept of reincarnation, where the soul is reborn into different forms after death, and he encouraged practices that would purify the soul, such as living a virtuous life and following strict routines. His philosophy included a strong ethical component, promoting self-discipline, kindness, and the pursuit of wisdom.


Additionally, Pythagoras founded a community that blended scientific inquiry, spiritual beliefs, and a focus on personal development. His followers, known as Pythagoreans, sought to live in harmony with his teachings, which reflected a balance between reason and spirituality. Overall, Pythagoras’s philosophy reveals a fascinating approach to understanding life and the cosmos, uniting logic, faith, and ethics.
What is immortality of the soul?
Pythagoras, the ancient Greek philosopher and mathematician, believed strongly in the immortality of the soul. He thought that the soul was eternal and did not perish with the body. According to his teachings, the soul exists independently of the physical form and continues its existence after death. Pythagoras also believed in the concept of reincarnation, where the soul transitions into a new body after leaving the old one. This cycle of rebirth, often referred to as transmigration, was central to his philosophy. To Pythagoras, the soul was not only immortal but also carried with it the essence of a person’s being, including their knowledge and experiences. He taught that the soul undergoes purification through these cycles, ultimately striving to achieve a higher, more enlightened state. This perspective influenced many of his followers and shaped ideas about the soul in later philosophical and spiritual traditions.
This example helps to demonstrate this philosophical perspective. One story that reflects Pythagoras’s view of the soul’s immortality involves his belief in the transmigration of souls, or reincarnation. It is said that Pythagoras once claimed he could recognize the soul of a friend who had passed away now residing in the body of an animal. This story highlights his conviction that souls do not perish with the body but continue to inhabit new forms after death. According to tradition, Pythagoras believed that every soul moves through a cycle of births and rebirths, taking on the physical form of different living beings. This belief emphasized the interconnectedness of all life and inspired Pythagoras to live in harmony with other creatures. The idea also played a role in shaping his moral practices, including his choice of a vegetarian diet, which avoided causing harm to animals.
Challenges to Pythagoras’s view about immortality of the soul
Some philosophers have objected to or rejected Pythagoras’s view of the immortality of the soul for various reasons, often stemming from differing perspectives on the nature of existence, consciousness, and evidence. A key objection arises from the lack of empirical evidence supporting the idea of an immortal soul. Philosophers rooted in materialism argue that the mind and consciousness are byproducts of physical processes in the brain, which cease entirely when the body dies. From this perspective, the notion of an immortal, non-physical soul does not align with observable, scientific understanding of life and death.
Others critique the concept as being based on metaphysical or religious assumptions, rather than reasoned argument grounded in evidence. Philosophers such as David Hume expressed skepticism about beliefs unsupported by tangible proof, emphasizing the need for logical reasoning over speculation. Furthermore, some argue that the belief in an immortal soul could stem from a psychological desire to offer comfort against the fear of death, rather than it being a reflection of reality. This reliance on faith or personal hope is seen by critics as undermining the validity of the idea.
Another line of objection comes from existentialist and naturalist philosophers who emphasize the finality of life. They argue that defining human existence solely within the bounds of birth and death adds urgency and meaning to life itself. For them, the belief in an immortal soul diminishes the importance of living fully in the present, as it potentially shifts focus to an imagined afterlife.
Finally, some thinkers find faults in the logical consistency of immortal soul arguments. They question how a soul might exist without a physical body, or how such an immaterial thing could interact with our tangible world. These concerns point to the lack of a clear and coherent explanation of what an immortal soul truly entails or how it functions, making the concept difficult to accept on rational grounds.
Overall, while the idea of the immortality of the soul may hold emotional or spiritual appeal to many, its critics highlight significant philosophical and scientific challenges that raise doubts about its validity.
Why immortality of the soul is important to Pythagoras’s philosophy
These are some of the main reasons why grasping the concept of the soul’s immortality is essential to comprehending Pythagoras’s philosophy.
- Connection to Ethics and Morality
The idea of the soul’s immortality is central to understanding how Pythagoras linked philosophy to ethics and morality. Pythagoras believed that the soul was eternal and moved through various forms of existence. This belief introduced a framework where individuals were encouraged to act virtuously, as their actions in life could influence the soul’s future experiences. This sense of accountability to a larger cycle made ethical living a necessary component of daily life. It connected personal choices to a broader, unending cycle of existence. By embedding morality within the larger concept of an immortal soul, Pythagoras’s philosophy encouraged people to reflect deeply on how their actions had both immediate and far-reaching consequences.
- Influence on Harmony and Order
The immortality of the soul reinforced the importance of harmony and order in the Pythagorean view of life and the universe. If the soul continues beyond a single lifetime, the choices made in this life are interconnected with a greater universal balance. This idea helped Pythagoras emphasize the role of living in tune with the natural order—whether this meant following a disciplined lifestyle or observing the mathematical patterns he saw in the cosmos. The belief in the soul’s immortality made the pursuit of harmony not just a practical goal but a spiritual imperative, as the soul’s eternal existence was thought to be sustained by aligning with the universal laws of order.
- Foundation for Personal Transformation
Immortality of the soul plays a significant role in Pythagoras’s ideas about self-improvement and growth. Pythagoras viewed life as an opportunity for the soul to progress and refine itself over time. While one lifetime might not achieve perfection, the soul’s immortality allows for continued development across different existences. This perspective underscores the importance of striving for wisdom, mastery, and discipline in each life. The concept not only inspired individuals to seek personal transformation but also ensured that this pursuit was seen as part of a grander, timeless process rooted in the soul’s eternal nature.
Contrasting Pythagoras’s philosophy with Thomas Hobbes’s philosophy
Pythagoras’s belief in the immortality of the soul sets his philosophy apart from that of Thomas Hobbes, as their views on human nature and the essence of existence differ fundamentally. Pythagoras saw the soul as eternal and central to understanding life and the universe. For him, the soul transcended the physical, achieving purification and potentially reaching a divine, lasting state. This focus on the soul’s immortality aligns with a more spiritual or metaphysical worldview.
On the other hand, Hobbes held a more materialistic perspective. He argued that human beings and their experiences, including thoughts, emotions, and consciousness, are entirely grounded in physical matter. Hobbes did not believe in the immortality of the soul or the afterlife; instead, he viewed humans as complex biological machines, and life as the movement of matter. Once the body ceased to function, Hobbes believed, so did the individual’s existence.
These contrasting beliefs reflect their distinct approaches to philosophy—Pythagoras emphasized a metaphysical, spiritual dimension, while Hobbes prioritized a scientific, materialistic understanding of reality. This divergence highlights how each thinker sought to interpret human existence through opposing lenses, shaping their broader philosophical contributions.
Immortality Of The Soul, Pythagoras’s philosophy and the philosophy of life
Reflecting on Pythagoras’s view of the immortality of the soul, whether we agree with it or not, plays a vital role in shaping our own philosophy of life. At its core, contemplating such ideas forces us to think about what we believe in, not just about life and death, but about the meaning and purpose of existence itself. Even if we do not share Pythagoras’s perspective, engaging with his ideas can expand our understanding and prompt us to question assumptions we might have taken for granted.
The importance of this reflection lies in its ability to provide clarity about our values and priorities. For instance, considering the possibility of an immortal soul might inspire thoughts about how we define a “good life.” It could encourage us to act in ways that align with long-term, universal principles rather than fleeting concerns. Even denying the concept of an immortal soul could guide us toward cherishing the present moment and finding meaning in the here and now. Either way, wrestling with these contrasting views helps us better define what we’re striving for in our daily choices and interactions with others.
Furthermore, reflecting on such philosophical perspectives can help us develop emotional resilience. Thoughts about mortality or the nature of the soul often lead to introspection about fear, loss, and our place in the larger universe. By engaging with these ideas, we may be better equipped to face uncertainty. This kind of reflection doesn’t just engage the mind; it can also strengthen our spirit and help us maintain composure when life feels overwhelming.
Ultimately, Pythagoras’s philosophy reminds us of the importance of examining life through a thoughtful lens. Even if his specific ideas don’t resonate, grappling with them adds depth to our understanding of ourselves and the world around us. Developing a personal philosophy requires openness to ideas, even those we might initially find foreign or difficult to accept. This intellectual exercise helps us grow, fostering a sense of purpose and direction as we continue to shape the way we live our lives.
