Can I just say, I wouldn't say the Enlightenment Ideal is all but gone. It's not even near death.
We, the people, chose leaders and were betrayed. That doesn't just apply to the US, but I'll start there. I believe the people were half-awake...but not completely unaware of who they were electing or what they would lose.
The idealist's battle against tyranny on one side and anarchy on the other is strewn all across the pages of history. Some idealists lost their way. But the ideals, "Safety and Happiness" – really, the entire Declaration of Independence or the UN Declaration of Human Rights – the ideals don't die.
They are self-evident. Like 3.14159 and 2.71828.
