Candide.
"It is demonstrable that things cannot be otherwise than as they are; for as all things have been created for some end, they must necessarily be created for the best end.”
That means that we live in the best of all possible worlds, because it is the only possible world, given all the conditions at hand and the history that got us here. That is an irrefutable statement given entropy and the anthropic principle.
Do you see the truth in this?
Just to set the context,
Candide is a
satiric novel by Voltaire. Pangloss, one of the central figures (whence the adjective Panglossian) is perhaps a satirical portrait of Leibnitz. He is an
absurdly optimistic philosopher who maintains his optimism in the face of all kinds of human suffering and pain. The quote above is an example of his philosophy.
Candide was written partly in reaction to the
devastating Lisbon earthquake of 1755, in which 30 to 50 thousand men, women and children perished, and which caused extreme consternation throughout Christian Europe: how could God allow such suffering? Apparently they hadn’t yet figured out the modern-day dodge: God is punishing Lisbon because gay marriage.
