Whether looking at a human maturing or the progress of civilization, the idea about what Reality is, keeps on changing. And mostly it changes toward the more complex, more elusive, more difficult to understand. The phenomenon is well known and has been expressed by children and philosophers alike, eg. "There are more questions than answers". George Musser expresses it thus:
The deeper that physicists dive, the more the concept of reality keeps swimming away from them. - https://blogs.scientificamerican.com/observations/is-reality-digital-or-analog-read-the-essays-and-cast-your-vote/
One may be tempted to suppose that this very receding nature of ultimate answers is an ultimate feature of Reality, a phenomenon worthy of investigation even.
Question: Does the phenomenon itself tell us something about Reality? Is there any literature that explores this?
