Quote 19
Do you believe in reincarnation? I ask.
"Perhaps"
What would you come back as?
"If I had my choice, a gazelle." (15.59-62)
Morrie and Mitch are willing to entertain the idea of reincarnation. The idea of being born again as a different creature comes from the Hindu faith. This idea doesn't come up a lot and they aren't even saying that they definitely think it's a true idea, but Morrie is willing to think of it as an option.
Quote 20
"The problem, Mitch, is that we don't believe we are as much alike as we are. Whites and blacks, Catholics and Protestants, men and women. If we saw each other as more alike, we might be very eager to join in one big human family in this world, and to care about that family the way we care about our own." (21.30)
Morrie is saying that despite what each of us believes, we should be able to recognize what makes us all the same—faith shouldn't be something that keeps people apart. Clearly, Morrie values this one human family more than particulars about what put us here on earth and where we'll go afterwards.
Quote 21
I wanted that clarity. Every confused and tortured soul I knew wanted that clarity.
"Ask me anything," Morrie always said.
So I wrote this list:
Death/ Fear/ Aging/ Greed/ Marriage/ Family/ Society/ Forgiveness/ A meaningful life (10.31-34)
Mitch makes a list of all the things about life that he wants clarified. These are things that he wishes he could understand in order to understand his own existence. Part of human existence is to question things; we're able to understand so much, but so much is left unanswered.
