Presocratics Part 2: Mathematics, Atoms, and Logic

The video explores the evolution of Western philosophy, starting with the Eliatic School and its monistic views. Zeno's paradox challenges the concept of movement, while pluralists like Anaxagoras and Empedocles introduce the idea of multiple elements. The Abdera School, led by Democritus, lays the groundwork for atomic theory. Diogenes revisits Anaximenes' ideas, and the sophists shift focus to ethics and rhetoric. The video concludes with the transition to classical philosophy, setting the stage for Socrates, Plato, and Aristotle.
