We live in a world in which people are censured, demoted, imprisoned, beheaded, simply because they have opened their mouths, flapped their lips, and vibrated some air. Yes, those vibrations can make us feel sad or stupid or alienated. Tough shit. That's the price of admission to the marketplace of ideas. Hateful, blasphemous, prejudiced, vulgar, rude, or ignorant remarks are the music of a free society, and the relentless patter of idiots is how we know we're in one. When all the words in our public conversation are fair, good, and true, it's time to make a run for the fence.

The belief-transmission network of which we are a part cannot operate without a continuously replenished supply of people to do the transmitting, thus the belief that children are a source of happiness becomes a part of our cultural wisdom simply because the opposite belief unravels the fabric of any society that holds it.

Beyond the satiation level of income, you can buy more pleasurable experiences, but you will lose some of your ability to enjoy the less expensive ones.

Perhaps the strangest thing about this illusion of control is not that it happens but that it seems to confer many of the psychological benefits of genuine control.

As students of the silver screen recall, Bogart's admonition about future regret led Bergman to board the plane and fly away with her husband. Had she stayed with Bogey in Casablanca, she would probably have felt just fine. Not right away, perhaps, but soon, and for the rest of her life.

In short, we derive support for our preferred conclusions by listening to the words that we put in the mouths of people who have already been preselected for their willingness to say what we want to hear.

Research suggests that people are typically unaware of the reasons why they are doing what they are doing, but when asked for a reason, they readily supply one.

Why isn’t it fun to watch a videotape of last night’s football game even when we don’t know who won? Because the fact that the game has already been played precludes the possibility that our cheering will somehow penetrate the television, travel through the cable system, find its way to the stadium, and influence the trajectory of the ball as it hurtles toward the goalposts!

In short, if we adhere to the standard of perfection in all our endeavors, we are left with nothing but mathematics and the White Album.
