What Actually is Liberalism? An Objective Guide

Why did every society from the dawn of civilisation until the 1800s feel comfortable with slavery? In fact, what's the purpose of civilisation in the first place? What makes a good society? What is 'good' itself?'Liberalism' shouldn't be conflated with being a 'liberal': this sociopolitical philosophy is in fact the foundation of Western politics/morality, and has been called the dominant ideology in world history. It is in fact arguably one of the most important things ever to happen to humanity, and has had an unimaginable impact on the human condition. So what is it?Today, in just 20 minutes, we answer that question objectively, thoroughly, and from an interdisciplinary perspective. There are no opinions or 'hot takes' here: it's all just expert consensuses.On Polymath, I've been producing a series called 'An Objective Guide to Political Ideologies'. I'm going to be remaking these episodes in the format of 20 minute 'Polymath Bites' summary episodes, so stay tuned for more 20 minute content about capitalism, socialism, communism, and more. Enjoy!
