Reality and its perception can be a fickle thing. Do we believe in the reality we're living right now, or is there one more absolute than that? Would we be able to believe in an absolute reality? This leads us into more questions, such as whether democracy is so good (or bad) and whether philosopher kings are ethical.
Plato's Allegory of the Cave presents the question "What is life?" and invites questioning into he reality we perceive to be true, and whether being shown another reality would be accepted. Human ignorance and unawareness are perceived to play into this, and so Plato's belief in philosopher kings as one way to overrule this can show. The ethics behind this were questioned this week though, with ideas such as perception and belief playing into it. Leaders can manipulate through misinformation, and monarchies can mean blood is greater than ideas. While this was an idea conceived over two thousand years ago, it's still relevant to this day, as we progress further and questions about the lives we live continue to grow.
