Conventional logic and thereupon based scientific systems largely lack the ability to express dynamic contents adequately. They are too rigid, building on never changing conditions. New things are just added, not created by conversing the old. Fundamental changes would destroy the foundations of the whole system.

To avoid this, the basics were more and more abstracted and miniaturized, down to smallest building blocks and most general rules. Of these all sorts of things may be constructed. Meanwhile, however, the road from the most elementary preconditions to the real outcome has become unmanageably long and complex.

In practice nobody goes the whole way. For single purposes specific models are in use. Although these should principally be reducible to those generally accepted foundations, this is actually not practicable at all. What ultimately counts is to find and to establish the methods fitting for a particular purpose.

The problem is that this common – and, besides, the only realistic – practice misses well-founded theoretical reasons. So there is no common ground for communicating about it. There exists no certain plan covering larger areas.
