Monsters are on the rise,though the reasons of the rise are hard to pin down.The uses of monsters vary widely.A crucial but often-ignored aspect of monsterology is the role those beasties play in our moral imaginations.Monsters can stand as symbols of human vulnerability and crisis,and as such they play imaginative foils for thinking about our own responses to menace.In a significant sense,monsters are a part of our attempt to envision the good life or the secure life.But imagining monsters is not just the stuff of fiction.
The monster concept is still extremely useful,and it's a permanent player in the moral imagination because human vulnerability is permanent.The monster is a beneficial foe,helping us to virtually represent the obstacles that real life will surely send our way.
The concept of monster cannot be erased from our language and thinking.It cannot be replaced by other more polite terms and concepts,because it still refers to something that has no satisfactory semantic substitute or refinement.Terms like "monster" and "evil" have metaphysical residue on them.But even if we neuter the term from obscure theological questions about Cain,or metaphysical questions about demons,the language still successfully expresses a radical frustration over the inhumanity of some enemy.The meaning of "monster" is found in its context,in its use.
Let’s not forget to take monsters seriously,too.But things don't strike fear in our hearts unless our hearts are already seriously committed to something.Ironically then,inhuman threats are great reminders of our own humanity.
