Mondo candido

Directed by Gualtiero Jacopetti

Voltaire, a 16th century author was furious that learned members of a "civilized" society could claim that the apparent senseless violence and mayhem wrought by disasters, war, disease, man's cruelty, etc. was actually only a part of some 'greater good'. After all, God (being perfect) could not 'logically' have created anything but the 'best of all possible' universes.
