What do the choices to buy cheap souvenirs, send a birthday present even when you don’t want to, or watch pornography have in common? They all involve your “perceptual intelligence” or PI. Physician Brian Boxer Wachler, an expert on vision and perception, explains PI, the aspects of your mind that sort truth from wishful thinking, self-deception from reality-based intuition and impulse from reason. His entertaining, ambitious treatise looks into human behavior, political activities and daily interactions. He raises fascinating, relevant issues about the complex ways people see the world. While never offering medical advice, getAbstract recommends his useful overview, which includes suggestions for improving your PI, critical thinking, self-understanding, health and self-control. His vivid examples and breezy tone may make the reasoning seem casual. Don’t be misled; his well-researched conclusions are educational and entertaining. 

In this summary, you will learn

  • How your “perceptual intelligence” (PI) functions,
  • Why PI matters and
  • How to improve your PI.

Real Experiences

What is the nature of reality? Is there a single objective reality? Is the world a shared illusion or a cluster of competing illusions? Some of these questions are philosophical, but others occupy the more ambiguous ground where biology meets philosophy and experience.
