If every negotiation is conducted in public, then the minute one person says, well, what if we try this, next thing you know, the interest groups have piled all in, and the political opponents have shot it to pieces.

What we have done over the last 40 or 50 years is systematically attacked and weakened the parties, the political machines, the professionals, and insiders, and hacks, and all the tools that they use to get politicians to play well together. And with those gone, you get chaos.

In a liberal scientific society, to claim that you are above error is the height of irresponsibility.

After an hour or two of being socially on, we introverts need to turn off and recharge ... This isn't antisocial. It isn't a sign of depression.

There were big problems with every system, and there always have been.

A liberal society stands on the proposition that we should all take seriously the idea that we might be wrong. This means we must place no one, including ourselves, beyond the reach of criticism; it means that we must allow people to err, even where the error offends and upsets, as it often will.

Donald Trump didn't cause chaos. Chaos caused Trump.
