The Logos

Humans subconsciously 
Operate on a code of ethics
inherent in our nature
Called the Logos.
When that code begins to break down
The society breaks down.
When strange questions arise
About simple matters,
Such as "What constitutes Gender?"
"What role does monogamy play in society?"
"When ought I get a divorce?"
"Does God exist?"
The Logos governing that civilization
Gets warped, and the society ceases to be cohesive.
What ultimately collapses society is that when the Logos is not trusted
The civilization breaks down morally, 
And other kingdoms will swoop in and take it over.
Or, the society will be given into rampant corruption, chaos, tyranny and general unhappiness.
I suspect the time Christ will return
Is when no country on Earth understands the Logos.
And when all men are sophists.
