Viability
Viability is a concept of radical constructivism and can be traced back to Ernst von Glasersfeld . The term is a derivative or word formation of the word viabel , which initially means practicable , suitable , useful or functional .
Feasibility; Validity of constructions of reality or the selected alternative ( contingency ), as long as these prove themselves in practical action or are useful. It is an important criterion of relevance for the constructions of reality in addition to connectivity and targetability.
Viability in constructivism
Since, in the opinion of radical constructivism, it is not possible to match convictions with reality, it dispenses with a concept of truth. Instead of this term, he uses the term viability as the criterion for convictions.
"Actions, terms, and conceptual operations are viable when they fit the purposes or descriptions for which we use them."
Examples
A captain who crosses a strait with shallows without an echo sounder and a nautical chart without a collision has found a viable path, there may be 1000 other viable paths (possibilities to cross the strait without a collision).
As Albert Einstein has shown, Isaac Newton's physics represents the conditions as they can be assumed at low speeds. Newton's physics is viable for small speeds well below the speed of light . So viable that z. B. Landings on the Moon or Mars can be calculated with their formulas. However, Newton's physics is no longer viable when it comes to bodies whose speed approaches the speed of light.
