In "The Man in the Iron Mask," Alexandre Dumas explores the idea that some misfortunes in life are so difficult to accept that individuals may turn to belief in the supernatural or the impossible as a form of escape. This reflects a tendency in human nature to seek explanations beyond the rational when faced with harsh realities.

Dumas suggests that these beliefs can provide comfort or a semblance of understanding in a world filled with inexplicable challenges. Rather than confronting painful truths, people may find it easier to embrace fantastical ideas, highlighting the struggle to cope with life's adversities.
