“both doubt and certainty are as contagious as the common cold”

“doubt is a skill. credulity ,by contrast, appears to be something very like an instinct”

“The idea behind the meta-induction is that all of our theories are fundamentally provisional and quite possibly wrong, if we can add that idea to our cognitive toolkit, we will be better able to listen with curiosity and empathy to those whose theories contradict our own. We will be better able to pay attention to counterevidence - those anomalous bits of data that make our picture of the world a little weirder, more mysterious, less clean, less done. And we will be able to hold our own beliefs a bit more humbly, in the knowledge that better ideas are almost certainly on the way.”

“Our love of being right is best understood as our fear of being wrong”

“without being sure of something, we can not begin to think about everything elses”

“To err is to wander and wandering is the way we discover the world and lost in thought it is the also the way we discover ourselves. Being right might be gratifying but in the end it is static a mere statement. Being wrong is hard and humbling and sometimes even dangerous but in the end it is a journey and a story. Who really wants to stay at home and be right when you can don your armor spring up on your steed and go forth to explore the world True you might get lost along get stranded in a swamp have a scare at the edge of a cliff thieves might steal your gold brigands might imprison you in a cave sorcerers might turn you into a toad but what of what To fuck up is to find adventure: it is in the spirit that this book is written.”

“Granted it is easy at least comparatively to find pleasure in error when there's nothing at stake. But that can't be the whole story since all of us have been known to throw tantrums over totally trivial mistakes. What makes illusions different is that for the most part we enter in them by consent. We might not know exactly how we are going to err but we know that the error is coming and we say yes to the experience anyways. In a sense much the same thing could be said of life in general. We can't know where your next error lurks or what form it will take but we can be very sure that it is waiting for us. With illusions we look forward to this encounter since whatever minor price we paid in pride is handily outweighed by curiosity at first and by pleasure afterward. The same will not always true when we venture past these simple perceptual failures to more complex and consequential mistakes But nor is willing the embrace of error always beyond us. In fact this might be the most important thing that illusions can teach us: that is is possible at least some of the time to find in being wrong a deeper satisfaction then we would have found being right.”
