1. in Dn, there is a new way of thinking about things which underlies a great deal of its technology. Instead of two-valued logic or three-valued logic we have infinity-valued logic. Here is a gradient scale which permits no absolute at either end. In other words, there is not an absolute right and an absolute wrong, just as there is no absolute stillness and no absolute motion. Of course, it is one of the tenets of Dn that absolutes are not attainable but only approachable.
