Welcome back, Alan. You've now completed all of Topic 1 — a thorough journey through the Pre-Socratics, from Thales through the Atomists. This lesson picks up exactly where that left off, moving into Topic 2: Socrates and the Sophists.
After nine lessons' worth of cosmology and metaphysics, this lesson marks the famous pivot — where philosophy turns from the heavens to the human being. Here's what this lesson covers:
Features
- 2.1 The Sophists — who they were and why relativism genuinely threatened philosophy
- 2.2 Socrates vs. the Sophists — what it means to know that you don't know
- 2.3 The Socratic Method — how elenchus works, with a deep dive into the Euthyphro
