'For my part, Sir,' replied the scholar, 'I think nothing of the sort. I find that all goes wrong with us, and that no one knows his place in society or his proper employment.' (pg. 104)
Candide ends up in a supper, surrounded by nobles and wealthy people. Here, he meets a gentleman who seems to be educated philosophically. Candide mentions Dr. Pangloss' ideas and asks this man what his opinion is on the subject. This man believes the complete opposite and thinks that absolutely everything is wrong with the world and humans.
Here, Voltaire presents two complete different philosophies that are both equally as absurd. However, these two philosophies are exactly what we think once we have accomplished something or have failed at doing so. When we do succeed we automatically think, "things aren't at all bad" or "I could not be any happier." These are definitely broad statements, but they demonstrate that our perspective of life depends on our current situation.
It is highly unlikely for someone to believe that life is completely fair and that everything is for the best when they are parched, homeless, and weak. In this scenario the person is probably going to frown upon society and our way of living. Therefore, those who live happily may agree with Pangloss' ideas more than those who strive to survive.
In life things are not all for the worst or for the best at all. We cannot say that humans are naturally evil because there is not one single person that is going to be "evil" according to everyone. In general, everyone has a little bit of everything and should not be stereotyped under one characteristic. It is easy for us to judge society and conclude that people are naturally good or evil, but we have to focus more on what we aport to it. In other words, be the change and don't criticize how others act. If you disagree with something you should definitely make your point by trying to fight against it.
