Eldorado- The Perfect Society
Eldorado, Voltaire's utopia, is representative of the way Voltaire believes society should be. Nobody is poor or oppressed, nobody is concerned with money, and there are no distinctions between social classes. This is quite the opposite of Europe, which is characterized by greed, wars, and exploitation of individuals for profit (i.e. sugar comes at the cost of slave labor under brutal conditions). Candide further reinforces the greediness of Europeans by leaving Eldorado with its gold to find Cunegonde, rather than seeing that the perfect life was right in front of him.
Piety vs. False Piety
Like in Tartuffe, religious hypocrisy is a main theme. In Holland, where people were supposedly pious, Voltaire runs into a preacher who speaks about love and charity, but the preacher won't help him because they have differing opinions about the Pope.
Jacques the Anabaptist is an example of true piety, someone who sacrifices himself for others. The Anabaptists believed in adult baptism so religion wasn't forced upon young children who can't yet make decisions themselves. Also, Jacques teaches Candide how to make rugs while taking care of him, and ultimately, he dies by sacrificing himself to save a sailor from drowning. Voltaire believed giving to others and sacrifice are necessary for humans to reach Eldorado- the perfect society.
