> "... writing with a strong constraint, which makes you think more." I agree. E-Prime was inspired by General Semantics ( see e.g. http://en.wikipedia.org/wiki/General_Semantics http://en.wikipedia.org/wiki/General_Semantics , the "Overview" section on that page seems sufficient), though, and had a much more specific motive than just improving writing. While E-Prime can focus too much on just "is", I think it seems like an approachable introduction to the ideas. I also thought they might be of interest here, because there's a neat parallel between them and e.g. thinking about is-a/has-a in OO design, the ways having quote empowers Lisp, etc.
