Thanks to Skyler for bringing up this word, shall, in this blogspace. There is a strong argument that any time this word and its variations are used relative to human behavior that it is poorly used. There is also a weak argument that it might be used in a process description, say in a statute where it only applies to what generically happens next — but there are other words which may substitute nicely. The word shall (and its derivatives) actually comes to us from the KJV Bible[*], where it was frequently used to describe the mandatory nature of man’s relationship to God. But it was soon usurped by Kings and other despots who were running a scam that they had a divine right to practice their depradations on those without divine right. (We’ll do a WPU on “divine right” perhaps one day). The use of shall might well be done away with in modern usage. It is a vestigial remain. Part of the behavior of poorly using words is to preserve the use of words that no longer have a practical use (its power to confuse massively outweighs its power to clarify).
