This is the man who read 2,000 years of human thought and said, "You don't actually know anything, your morality is just feelings, causality is a lie, and you don't exist. Have a great day."

In this wildly bitter, hysterically sharp takedown of Enlightenment optimism, Sophia Blackwell (author of I Think, Therefore I'm Wrong and Why Did That Happen?) guides you through:

• Hume's obsession with impressions and ideas (aka "Your brain is faking it")
• His complete annihilation of cause and effect ("Just because the sun rose yesterday...")
• The revelation that you have no self, just a slideshow of mood swings
• His polite-but-lethal evisceration of religion, miracles, and divine nonsense
• Why ethics is just your emotional nausea dressed up as virtue
• And how Hume managed to ruin the entire Enlightenment without raising his voice once

Read it. Doubt everything. Try not to cry.
