The field of philosophy has been a cornerstone in shaping the world’s intellectual and cultural heritage. Since ancient times, philosophers have posed questions about knowledge, existence, morality, and the nature of mind and matter. Among them, a select few have etched their names into history not only for their profound contributions but for the era they belonged to, making them some of the oldest philosophers known to humanity.
In this article, we will explore ten of these ancient thinkers, delving into their lives, their philosophies, and how their ideas have transcended time to influence our world today. Following this, we will address some frequently asked questions and conclude with a reflection on the enduring legacy of these venerable sages.
Oldest Philosophers in the World
1. Thales of Miletus
Thales of Miletus is often regarded as the first philosopher in the Western tradition. Living around 624–546 BCE, he is one of the Seven Sages of Greece and is famously known for his assertion that “water is the principle of all things.” Thales’ philosophy laid the groundwork for a naturalistic explanation of the world, moving away from mythological interpretations.
He believed that every event had a natural cause, thereby laying the seeds for scientific inquiry. Moreover, his work in geometry, particularly in measuring the heights of pyramids and distances of ships from the shore, showcases his innovative approach to understanding the world.
2. Anaximander
A pupil of Thales, Anaximander of Miletus lived from 610 to 546 BCE. He is best known for his theory that the primary substance was not water, as Thales proposed, but something he called the “apeiron” or the infinite.
Anaximander’s concept of the apeiron was groundbreaking, suggesting an eternal and ageless substance that underlies all change. He also contributed to the fields of geography and astronomy, theorizing about the structure of the Earth and floating celestial bodies on vast spaces.
His work significantly impacted the development of the scientific method, emphasizing observation and rationality.
3. Pythagoras
Pythagoras, who lived between circa 570–495 BCE, was more than just a philosopher; he was also a mathematician and a spiritual leader. His famous theorem, Pythagoras’s theorem, remains a fundamental principle in mathematics. Pythagoras believed in the immortality of the soul and that the soul could transmigrate between species.
He held that number was the ultimate reality, underlying all structures in the universe, thus offering a mystical view of numbers. The Pythagorean community he founded was one of the earliest examples of a commune based on shared philosophical and spiritual beliefs.
4. Heraclitus
Heraclitus of Ephesus, active around 535–475 BCE, is famous for his enigmatic assertion that “you cannot step into the same river twice.” He believed in the ever-present state of change, encapsulated in his doctrine of perpetual flux. According to Heraclitus, everything flows, and opposite forces are interconnected, leading to a harmonious unity.
His work pays homage to the complexity of the world, emphasizing conflict and contradiction as central to understanding the nature of life. Despite the fragmentary nature of his writings, Heraclitus has had a lasting impact on the philosophical concept of change and becoming.
5. Parmenides
Parmenides, flourishing around 515 BCE, offered a strikingly different view from Heraclitus. He argued that the reality is singular, unchanging, and can be discovered only through reason, not sensory experience.
According to Parmenides, change is an illusion, and the universe is a continuous, unchanging entity. This idea challenged the philosophical and scientific thought of his time, forcing thinkers to confront the paradoxes arising from the notions of change and permanence. His dialectical method of argumentation laid the groundwork for later philosophers, including Plato.
6. Socrates
Socrates of Athens (470–399 BCE) is perhaps the most renowned of all ancient philosophers. He is known for his Socratic method—a form of cooperative argumentative dialogue to stimulate critical thinking and to illuminate ideas. Socrates believed in the pursuit of goodness and knowledge as the highest aims of human life.
He left no writings behind, but his teachings were immortalized by his students, particularly Plato. His death by hemlock, a result of his unwavering commitment to his philosophy, marks one of the most famous moments in the history of philosophy.
7. Plato
A student of Socrates, Plato (428/427–348/347 BCE) founded the Academy in Athens, the first institution of higher learning in the Western world. Plato’s dialogues, in which Socrates is often the main character, have been instrumental in shaping Western philosophy. He introduced the theory of Forms, abstract perfect entities, of which objects in the physical world are imperfect copies.
Plato also explored ethics, politics, virtue, and the nature of knowledge, creating a foundation that would influence countless generations of thinkers. His idealistic vision includes the notion of an ideal state ruled by philosopher-kings.
8. Aristotle
Aristotle (384–322 BCE), a student of Plato, became one of the most influential philosophers in history. Unlike his teacher, Aristotle focused on empirical observation and the nature of physical reality. His works cover a wide range of topics, including logic, metaphysics, ethics, politics, and science.
Aristotle’s method of logic, known as syllogism, became the backbone of Western analytical thinking. Furthermore, his classification of living organisms and his exploration of the human soul’s properties laid the groundwork for both biology and psychology.
9. Zeno of Elea
Zeno of Elea (circa 490–430 BCE) is best known for his paradoxes, which challenge our understanding of motion and space. A student of Parmenides, his paradoxes were devised to support Parmenides’ doctrine that contradicts the existence of plurality and change.
Zeno’s paradoxes, such as the famous “Achilles and the Tortoise,” illustrate the complexities of infinity and have puzzled mathematicians and philosophers for centuries. His work has had a profound impact on the development of mathematical theory, especially in the field of calculus.
10. Empedocles
Empedocles (circa 490–430 BCE) was a philosopher, statesman, and poet who articulated the theory of the four classical elements—earth, air, fire, and water—as the foundation of all matter. He also proposed the forces of Love and Strife as the causes of creation and destruction in the universe.
Empedocles’ philosophical poems offered a cosmological theory that combined elements of Pythagoreanism and the teachings of Parmenides.
His contributions laid significant groundwork for the development of chemistry and the understanding of the natural world. Empedocles’ legacy demonstrates the intersection of philosophy, science, and art in ancient thought.
