 This presentation by Rich Hickey, ["Simple made Easy"](http://www.infoq.com/presentations/Simple-Made-Easy) is also an excellent reflection on these values.
 
-We follow a set of ideas that started with Jean Piaget's [Constructivism](https://en.wikipedia.org/wiki/Constructivism_(philosophy_of_education)), and later explored in Seymour Papert's [Mathland](https://en.wikipedia.org/wiki/Experiential_learning). These lead to Alan Kay's Learning Research Group's [Personal Computer for Children of All Ages](http://www.vpri.org/pdf/hc_pers_comp_for_children.pdf), [Personal Dynamic Media](http://www.vpri.org/pdf/m1977001_dynamedia.pdf), i.e. the [Dynabook](http://www.vpri.org/pdf/hc_what_Is_a_dynabook.pdf) and then to [Smalltalk-80](https://en.wikipedia.org/wiki/Smalltalk). To us, a Smalltalk system is a Dynabook. A place to experiment and learn, and a medium to express the knlowledge we acquire. We understand software development as the activity of learning and documenting knowledge, for us and others to use, and also to be run on a computer. The fact that the computer run is useful is a consequence of the knowldege being sound and relevant. (Making it run is _not_ the important part!)

 Cuis Smalltalk is our attempt at this. Furthermore, we believe we are doing something else that no other Smalltalk, commercial or open source, does. We attempt to give the true Smalltalk-80 experience, and keep Smalltalk-80 not as legacy software to be run in an emulator, but as a live, evolving system. We feel we are the real keepers of Smalltalk-80, and enablers of the Dynabook experience.
