SUMMARY:⚙️ Neo-Luddite Reading Group: 'The Technological Society' by Jacques Ellul
DESCRIPTION:➡️ Virtual Meetup Link\nDiscord: Email neoluddite@victorgom.es for an invite! \nFull schedule: victorgom.es/neoluddite \nIf you’re joining for the first time\, I’d suggest you read this before anything else for brief context: What the Luddites Really Fought Against by Richard Conniff.The only expectation is that you read the chapter(s) of the book that’s listed for that meeting. You’re still welcome to participate if you haven’t done the readings as long as you are mindful. For each chapter\, I’ve also noted some optional readings for context\, so I’d suggest checking those out rather than reading ahead in the book. And remember\, if you ever find yourself struggling with any of the readings or concepts\, reach out! Either directly to me over email or to the entire group over discord.
