> systems built upon illusions are less stable than systems built upon truths

I strongly disagree with that. The most stable societies historically have been built around a religious center, which is by definition not an objective rational truth. We are yet to see a very large group of people co-exist in an environment based on truths. So far we are witnessing quite the opposite: truth itself has acquired a new definition ("alternative facts", "my truth", etc).

Edit: for people who downvote this comment. Do you have an example of a stable society based on truths? Other than a speculation that this time humanity will succeed, and people will finally value truth over comfort.
