Feels like lots of the titles people suggest here are for some sort of quirky paperback self-help bestseller. You want to be one of those weighty, widely discussed New York Times bestsellers. These seem to me like the kind of titles you want to emulate:

• Thinking, Fast and Slow
• Brainstorms
• Brainchildren
• How the Mind Works
• The Emperor's New Mind
• Metamagical Themas
• Gödel, Escher, Bach: An Eternal Golden Braid

Titles that others have used in the past that I don't recommend:

• How to Write, Think and Speak Correctly :)
