    SLIDE 1: Title Slide – “Anaximander: Pioneer of Western Philosophy” Okay, here’s a question for you: Who invented the idea that Earth floats in space? No, not Copernicus. Not Galileo.

    # SLIDE 1: Title Slide – “Protagoras: The Measure of All Things” Okay, here’s a question for you: Is there such a thing as truth with a capital T? I mean, really think about it.

    SLIDE 1: Title Slide Okay, so here’s a question that’s probably crossed your mind at some point: What if everything you’re absolutely certain about… is wrong? Not just a little wrong. Not “oops, I misread the data” wrong. But fundamentally, completely, can’t-even-know-if-you’re-wrong wrong. Now, most philosophers throughout history have heard that question and responded with…

    SLIDE 1: Title Slide “Thales of Miletus: The First Greek Philosopher” Okay, picture this: It’s around 585 BCE. Two armies—the Lydians and the Medes—are locked in a brutal battle.

    Slide 1: Title Slide – “The Philosophy of Hippocrates: Father of Medicine and Medical Ethics” Alright, let’s talk about one of the most radical intellectual revolutions in human history – and I’m willing to bet most of you have no idea just how radical it actually was.

    Picture this. You’re living in ancient Athens. You wake up every morning terrified. Terrified that you’ve offended a god you didn’t even know you were supposed to worship. Terrified that when you die, you’ll spend eternity as a miserable shade in the underworld. Terrified that no matter how hard you work, no matter how much…

    SLIDE 1: Title Slide – “The Philosophy of Mozi: China’s First Consequentialist Thinker” Alright, here’s the thing – when most people think about ancient Chinese philosophy, they immediately jump to Confucius, maybe Laozi and the Taoists.
