Stupidity. It can't be bargained with. It can't be reasoned with. It doesn't feel pity or remorse or fear, and it absolutely will not stop, ever, until you are brain dead....

See also Friedrich Schiller [1]:

> Folly, thou conquerest, and I must yield!

> Against stupidity the very gods

> Themselves contend in vain.
