Illogical thinkers throw names and slurs around because they have no arguments with which to rebut their opponents. Rational people have to keep hammering their points home.

I first wanted to be a psychiatrist. I decided against that in medical school when I discovered that psychiatrists didn't, in reality, do what they did on TV.

A good surgeon doesn't just concentrate on technical ability, but also on the appropriateness of what you're doing.

If for you the most important thing is to make a lot of money, then you don't want to take a certain type of risk. If, on another hand, the most important thing to you is to make people around you have a more fulfilled life, then there is a different set of things that are important to you. Unless you really know that about yourself, you will never be able to appropriately assess risk.

If we set our priority "the removal of all risk", we'll soon have sterile, stagnant, and unstimulating learning environments.

Economics is not brain surgery.

There's no question that as science, knowledge and technology advance, that we will attempt to do more significant things. And there's no question that we will always have to temper those things with ethics.
