The Dream of Enlightenment: The Rise of Modern Philosophy
by Anthony Gottlieb
Philosophy
TL;DR
This book spills the tea on how a squad of 17th and 18th-century thinkers basically invented critical thinking as we know it. It's less about their personal drama and more about their mental toolkits. You'll learn how to radically doubt everything (Descartes' vibe check), build knowledge from scratch based on experience (Locke's 'your brain is a blank slate' energy), and challenge authority with your own damn reason (Kant's 'don't be a sheep' anthem). It's a masterclass in intellectual independence and how to construct your own worldview using logic and evidence, not just ancient vibes or what your parents told you.
Action Items
Pick one strong belief you hold and spend 5 minutes trying to find arguments against it. See if it still holds up.
Try a new food or activity you've always avoided. Pay attention to how your senses and feelings shape your opinion, rather than relying on preconceived notions.
Before sharing a viral post or accepting a widely held opinion, take 2 minutes to verify the information or logic yourself.
Observe a chain of events in your day (e.g., why you're late, why you're stressed) and trace back the interconnected causes, rather than blaming one single thing or person.

Key Chapter
Chapter - Descartes: The OG Doubter
This chapter dives deep into René Descartes, the OG influencer who basically told everyone, 'Hold up, what if everything we know is cap?' He kicked off modern philosophy by doubting literally everything – his senses, his memories, even if he was awake or dreaming. His big flex? The only thing you can't doubt is that you're doubting, which means you exist as a thinking thing. It's like when you're scrolling through endless TikToks and suddenly wonder if your whole life is just an algorithm. Descartes teaches us to strip away assumptions and build knowledge from a solid, undeniable foundation. Super useful for not getting scammed online or falling for fake news, forcing you to question your own biases before accepting them as truth.
Key Methods and Approaches
The 'Is This Even Real?' Check
(AKA: Radical Skepticism/Methodic Doubt)
Description:
Don't trust anything until you've tried to break it down and prove it wrong.
Explanation:
Imagine your brain is a cheap influencer trying to sell you detox tea. Descartes was like, 'Nah, fam, I'm not buying it.' He said, assume everything you think you know is a lie, even your own senses. It's like when you see a perfectly filtered selfie and you're like, 'Is that even the same person?' You gotta strip away all the filters and see what's actually there. If you can't doubt it, then maybe, just maybe, it's real.
Examples:
Your friend tells you a wild story about their ex. Instead of believing it instantly, you ask for receipts.
You see a 'get rich quick' scheme online. Your first thought isn't 'sign me up,' it's 'how is this a scam?'
Before buying a product, you check reviews from multiple sources, not just the brand's website.
