It seems that most contemporary societies have some sort of cultural dichotomy or culture war going on. In the West it is Left vs. Right. In Middle Eastern countries it is Secular vs. Religious. In India it is Hindu-nationalist vs. Multi-cultural Indians.
At first I was tempted to assume that this started because of the counter-culture in 1960s (and then spread to other cultures and got modified accordingly).
But then I realized that a lot of this ideological tensions predate the 1960s by a lot of time. In the Middle East, Secular-Nationalists vs. Religious dates to the early 20th century.
In Europe, Monarchist vs. Republican has been around since the French Revolution, etc....
So when exactly did having a cultural dichotomy/culture war mindset in any given society start? Was it the enlightenment? Or has it been always the case, since the beginning of civilized times (i.e. it is in a sense part of the human condition)?
