I came to know Douglas Kahn through his questions before I knew him through his background.

He is a deeply curious person.
When he encounters something, he is less interested in simply knowing what it is than in understanding why it came to be that way. When he sees a phenomenon, he looks for the principle moving beneath it. When he hears an explanation, he tests whether that explanation still holds in other situations.

This does not mean that he doubts everything or dismisses established ideas easily. If anything, he first tries to understand them. But familiarity alone is never a reason for him to stop thinking.

He steps slightly outside convention and habit, sometimes turns a problem upside down, and sometimes looks at it again from an entirely different position.

From there, things that once seemed unrelated begin to connect, and structures that were hidden inside the obvious start to reveal themselves.

He likes those moments.

Douglas does not pay much attention to the boundaries between fields. He may begin with economics and move into human behavior, talk about technology and return to history, or take a principle discovered in one system and test it in a completely different world.

To him, knowledge is less something to accumulate than material to connect.

That is why his thinking contains many hypotheses.
But he does not fall in love with his own hypotheses easily.

The more interesting an idea becomes, the more likely he is to search for the variable that could break it, or to look at it again from the opposite side. He is less interested in defending an idea than in discovering how far it can withstand scrutiny.

He has long enjoyed spending time alone, reading and thinking. He studied Social Science and Computer Science and worked for many years in systems analysis and design, but his curiosity never remained within the boundaries of a particular discipline or profession for very long.

Perhaps that is what best describes Douglas Kahn.

He is less interested in finding a single answer that explains the world than in continuing to understand how the world works.

And even when he thinks he understands something, he sometimes asks again:

What would it look like from somewhere else?

That is the Douglas Kahn I have come to know through our many conversations.
