“Of all the pessimistic people, I am the most optimistic. I look forward to looking down on all the people looking up to me for answers from below.”

“When asked if I am pessimistic or optimistic about the future, my answer is always the same: if you look at the science about what is happening on earth and aren't pessimistic, you don't understand the data. But if you meet the people who are working to restore this earth and the lives of the poor, and you aren't optimistic, you haven't got a pulse.”

“The the question whether I am a pessimist or an optimist, I answer that my knowledge is pessimistic, but my willing and hope are optimistic.”

“When asked if I am pessimistic or optimistic about the future, my answer is always the same: If you look at the science about what is happening on earth and aren’t pessimistic, you don’t understand data. But if you meet the people who are working to restore this earth and the lives of the poor, and you aren’t optimistic, you haven’t got a pulse. What I see everywhere in the world are ordinary people willing to confront despair, power, and incalculable odds in order to restore some semblance of grace, justice, and beauty to this world.”

“The spirit of the gospel is optimistic; it trusts in God and looks on the bright side of things. The opposite or pessimistic spirit drags men down and away from God, looks on the dark side, murmurs, complains, and is slow to yield obedience.”

“Well, some people say I'm pessimistic because I recognize the eternal cycle of evil. All I say is, look at the history of mankind right up to this moment and what do you find?”
