Question

Philosophically, what is the silver bullet?

Answer 1

It is the bane of any philosopher's existence.  Although they wax and pontificate endlessly about intransigent questions...the last thing they want is a definitive solution.  The last thing they want is the silver bullet.  Luckily, the silver bullet probably does not exist philosophically.

Answer 2

The silver bullet is the perfect answer, the solution sought, a strategy that cannot fail. It comes from the mythological idea that a silver bullet was required to kill a vampire or other beast.
