Access to information used to be scarce. We ranked college libraries on how many books they had, and time at the microfilm reader was booked in advance.

Today, if there’s something I don’t know, it’s almost certainly because I haven’t cared enough to find out.

I don’t understand molecular biology, the history of Sardinia or much of agronomy–but that’s my choice. Now that information is widely and freely available, our sense of agency around knowledge needs to change.

It pays to acknowledge that this is a choice, and to be responsible for it. What else have we chosen not to know?
