I'm okay, you're okay - in small doses.

People think that politics just somehow magically organizes itself. It doesn't work that way. You need to assemble these huge coalitions of 535 politicians on Capitol Hill, and tens of thousands of interest groups, and tens of millions of voters, and assemble all those in government to get stuff done.

Are introverts arrogant? Hardly. I suppose this common misconception has to do with our being more intelligent, more reflective, more independent, more level-headed, more refined, and more sensitive than extroverts.

In science we kill our hypothesis instead of each other.

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

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.

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