I remember one of my first lessons in at university by a philosophy professor. He was talking about Leibnitz and how he believed that the order in the world given by God was the best imagniable. If this world were different, it would be worse. The example was that in 1755 an eartquake hit Lissabon, Portugal, very hard causing ten thousands deaths. According to this theory it was the best imagniable, because in another world were those people wouldn’t have died more deaths would have occured (for example) somewhere else. And every “evil” in the world could give birth to a better thing (huge impact of philosophy and the European Enlightment). I found it a beautiful theory to explain the horrors, pains and suffering in the world.
He also told the story of a female professor he knew, of Jewish origin. She was a Leibnitzian and gave a lecture to an auditorium of students. After the lecture a student asked her about Leibnitzs theory and why God would have let the Jews being massacred during WWII. She repeated that it was the still the best imagniable world and also good came out of it. Without the concentration camp we wouldn’t for example have the exepticional art works made by the prisoners.
I probably didn’t express myself well in English and using philosophy in English would for me be a challenge of course. I hope my point didn’t go lost.
