I've debated many economists who claim to specialize in risk and probability: when one takes them slightly outside their narrow focus, but within the discipline of probability, they fall apart, with the disconsolate face of a gym rat in front of a gangster hit man.

We glorify those who left their names in history books at the expense of those contributors about whom our books are silent. We humans are not just a superficial race - we are a very unfair one.

If you see fraud and do not say fraud, you are a fraud.

If there is something in nature you don't understand, odds are it makes sense in a deeper way that is beyond your understanding. So there is a logic to natural things that is much superior to our own.

To succeed in life requires a total inability to do anything that makes you uncomfortable when you look at yourself in the mirror.
