The idea of [http://billkerr2.blogspot.com/2007/08/powerful-ideas-discourse.html non-universals] was started by Kay and furthered by Kerr. The idea being that all cultures spontaneously develop some ideas, for example art, but few cultures develop the more complex ideas, for example perspective drawing.

It is however a useful way to look at powerful ideas. | The idea of [http://billkerr2.blogspot.com/2007/08/powerful-ideas-discourse.html non-universals] was started by Kay and furthered by Kerr.
