Also on the legal level, foresight is not really predictable. Nobody really knows what may come. This uncertainty inevitably collides with the understandable desire for certainty, clarity and protection (also against overreaching). Our legal system on the one hand has the task to ensure agreements once achieved and to cement them so that in future better actionability is given, and on the other hand, law shall meet the requirements especially of the individual in his/her social context and thus it be dynamic, verifiable and thus changeable. Therefore, under the title "legal protection" there are well-tried ways and institutions (which of course also have their limits of wisdom).
