‘Deus ex machina’ is a device used in classical Greek plays to ensure that the action progresses to an ending that will satisfy the audience.
Literally, it means ‘ a God from a machine’, and it resulted in a happy outcome through the intervention of the supernatural.
The audience is, of course, pleased, for such a possibility in no way upsets or antagonises the beliefs of the time. On the contrary, confidence in the existence and benevolence of the Gods is reinforced.
In modern times, instead of Deus ex machina, we have close encounters of the third kind. The main difference would seem to be that the humanoids involved are not themselves Gods, but emissaries.
Parallel to such events in the Fifties, Sixties and Seventies, there were Men in Black (MIB) cases.
Though now popularly assimilated as the guardians of the planet, originally they were seen as something much more sinister.
MIB encounters vary somewhat, however, they usually involved men dressed in black suits delivering threats to UFO witnesses or researchers, indicating that unless they remained silent, dire consequences would ensue.
No physical violence following these threats has ever been reported by the brave individuals who chose to ignore the warnings.
Such events seem to be primarily attempts by the MIBs to learn what effect their actions precipitated and to what extent they could influence behaviour.
As in close encounters, there are usually logical inconsistencies. The strange appearance and conduct of the MIBs exhibited in many cases often resulted in a general sense of puzzlement.
Theories concerning their origin included military and intelligence organisations which only served to further confuse an already well obfuscated picture.
The fact that the MIB phenomenon no longer occurs woud suggest that it is no longer required, either because the objectives have been achieved, or more sophisticated means can now be employed to elicit the necessary information.
