Post filosófico do dia

"How many times must a man look up
Before he can see the sky?
How many ears must one man have
Before he can hear people cry?
How many deaths will it take 'til he knows
That too many people have died?
The answer, my friend, is blowin' in the wind
The answer is blowin' in the wind"

(Trecho de "Blowin' in the Wind", Bob Dylan)
