“Consider a more extreme example than the casino experiment. Assume a collection of people play Russian roulette a single time for a million dollars—this is the central story in Fooled by Randomness. About five out of six will make money. If someone used a standard cost-benefit analysis, he would have claimed that one has an 83.33 percent chance of gains, for an “expected” average return per shot of $833,333. But if you keep playing Russian roulette, you will end up in the cemetery. Your expected return is … not computable.”

“There are only two ways to live your life. One is as though nothing is a miracle. The other is as though everything is a miracle.”

“Pure mathematics consists entirely of assertions to the effect that, if such and such a proposition is true of anything, then such and such another proposition is true of that thing. It is essential not to discuss whether the first proposition is really true, and not to mention what the anything is, of which it is supposed to be true. [...] Thus mathematics may be defined as the subject in which we never know what we are talking about, nor whether what we are saying is true. People who have been puzzled by the beginnings of mathematics will, I hope, find comfort in this definition, and will probably agree that it is accurate.”

“Essentially, all models are wrong, but some are useful.”
