Speeding-up software engineering´s escape from its pre-paradigmatic stage

Software Engineering has been for at least a decade in a pre-paradigmatic stage, lacking a broadly accepted theoretical basis. But the repeated ritual of novel theories´ suggestion, enthusiastic adoption and subsequent decline, does not provide by itself enough thrust to escape the pre-paradigmatic stage. This paper promotes, concomitantly to novel theory proposal, active elimination of mistaken, irrelevant, undesirable notions among previous candidates. Specifically four NOT theorems are stated, justified and explained in the wider software engineering context.
