The Philosophy of Nagarjuna:The Middle Way of Emptiness 28.01.2026 39:46

Pythagoras: The Man, The Myth, The Mathematician 23.12.2025 1:48:47
When you hear a² + b² = c², you probably picture a high‑school geometry lesson. But Pythagoras was far more than a theorem‑maker. He was a traveler, a philosopher, a mystic, and the founder of a community that blended mathematics, music, and spirituality into a single vision of the universe. In the next few minutes we’ll separate the man, the myth, and the mathematician—tracing his early life on t...
Anaximander: Pioneer Western Philosophy 20.12.2025 2:15:16
Welcome! In today’s episode we dive into the mind of Anaximander, one of the earliest Greek thinkers and a key figure of the Milesian school. Living around 610–546 BC, Anaximander went beyond his teacher Thales’ idea that water is the fundamental substance and introduced the concept of the ‘apeiron’—an indefinite, boundless source from which all things emerge and return. He imagined the world as a...
Anaximenes of Miletus: Pioneer of Natural Philosophy 17.12.2025 1:18:20
Welcome, everyone! Today we travel back over 2,500 years to ancient Miletus, where a pioneering mind named Anaximenes set out to answer one of humanity’s oldest questions: What is everything made of? While his predecessor Thales pointed to water and his fellow Milesian, Anaximander, invoked the boundless ‘apeiron,’ Anaximenes proposed something far more familiar—air. He believed that all matter, f...

The Philosophy of Philo of Alexandria: Bridging Worlds 15.11.2025 1:20:50
We’re talking about a philosopher you’ve probably never heard of, living in a city that no longer exists, writing in a language most of us can’t read, about 2,000 years ago. And yet—and this is what blows my mind—his ideas are everywhere around you. In the Gospel of John. In Christian theology. In how we think about the relationship between faith and reason. In our very concept of the divine Word....
The Philosophy of Hippocrates 14.11.2025 1:13:26
You’ve heard of Hippocrates, right? “Father of Medicine.” Maybe you know about the Hippocratic Oath - doctors still swear some version of it today. But here’s what nobody tells you: this guy didn’t just invent some medical techniques. He fundamentally transformed how human beings understand reality itself. Think about this for a second. For thousands of years - literally thousands - when someone g...
The Philosophy of Epicurus : The Pursuit of Tranquility 13.11.2025 1:25:23
And into this world of grinding, suffocating anxiety walks a man who says something absolutely radical: “What if you could be free?” Not free someday. Not free in the afterlife. Free now. Free from the gods’ anger. Free from death’s terror. Free from the endless treadmill of desire that never satisfies. This is Epicurus. Note: To bring you the most comprehensive philosophy education possible, this...
The Philosophy of Mozi: China's First Consequentialist Thinker 13.11.2025 53:12
“China’s First Consequentialist Thinker.” Now, that’s a loaded phrase. We’re talking about someone who, over two thousand years ago, developed an ethical framework that judges actions based on their outcomes - their consequences - rather than on adherence to tradition or ritual. This is remarkable because in the Western philosophical tradition, we don’t see consequentialism fully articulated until...
The Philosophy of Lao-zi: The Sage of the Dao 11.11.2025 1:09:44
Lao-zi asks questions we’re all wrestling with in our modern world: What if you’re trying too hard? What if the secret to real power isn’t force, but flexibility? What if success doesn’t come from pushing harder, but from flowing better? “Hello, curious minds! I’m Lyon Leshley, a passionate educator with over 20 years of experience. I am taking full advantage of the AI revolution to provide free e...
The Philosophy of Democritus: The Laughing Philosopher and father of Atomism 10.11.2025 2:07:03
Alright, I want you to imagine something with me. It’s the 5th century BCE. You’re living in a world where everything—and I mean everything—gets explained by gods. Thunder? Zeus is angry. Earthquake? Poseidon’s having a bad day. Disease? You’ve offended Apollo. The universe is basically one giant divine soap opera, and you’re just trying not to get written into a tragic episode. And then there’s t...
The Philosophy of Appollonius of Myndus 09.11.2025 55:20
Alright, I need to tell you about someone who was right about something for two thousand years before anyone could prove it. Two. Thousand. Years. Imagine that. Imagine seeing something so clearly, understanding something so profoundly, that you’re correct about a fundamental truth of the universe and then humanity takes twenty centuries to catch up with you. That’s not just being ahead of your ti...
The Philosophy of Anaxagoras 08.11.2025 35:24
Picture this: Athens, 450 BCE. The most powerful democracy in the ancient world. The cultural and intellectual center of civilization. Philosophy, drama, art—everything that will define Western culture for the next two thousand years is happening right here, right now. And in the middle of all this brilliance, there’s a man standing in the agora—the marketplace—looking up at the sun. Not praying t...

What you’ll learn: • Who Th...
The Landscape of Ethical Philosophy 06.11.2025 1:27:07
Each of you carries within yourself a moral compass, shaped by family, culture, religion, and personal experience. But have you ever stopped to ask: Where did these beliefs come from? Are they universally true? Are there moral facts as concrete as mathematical theorems, or is morality simply a human construction, as variable as fashion trends? These are not merely academic questions gathering dust...
Axiology: The Philosophy of Value 25.09.2025 1:07:54

This philosophical discipline investigates the fundamental nature of value itself, examining what makes something valuable, good, or beautiful, and exploring how these determinations shape both individual experience and collective social organization. The field addresses questions that extend far...

The Quest for Knowledge: An Epistemological Journey 25.09.2025 1:18:31
Let us begin with a foundational question posed in one of the great dialogues of Western philosophy: What is knowledge? The inquiry into this question traverses centuries, starting with Plato’s dialogue Theaetetus.
