The Laboratorium : Code

I used to think that the Internet was inherently anti-authoritarian and unregulable; Lessig convinced me otherwise. Code is clear and precise; its treatment of the relationship between architecture and behavior is the most useful analytic framework I know of for thinking about the Internet. Many of its ideas are even more broadly applicable. Insights I use regularly:

The importance -- and mutability -- of physical architecture in shaping what is considered possible or reasonable.
The obvious-in-hindsight observation that cyberspace and meatspace are effectively coextensive: one is "in" both simultaneously.
The possibility of "latent ambiguity:" as society and technology change, we shouldn't expect old ideas and metaphors to remain applicable.
