“So what am I? I guess I would call myself a sober optimist...If you are not sober about the scale of the challenge, then you are not paying attention. But if you are not an optimist, you have no chance of generating the kind of mass movement needed to achieve the needed scale.”

“Pessimists are usually right and optimists are usually wrong but all the great changes have been accomplished by optimists.”

“At the end of the day, no amount of investing, no amount of clean electrons, no amount of energy efficiency will save the natural world if we are not paying attention to it - if we are not paying attention to all the things that nature give us for free: clean air, clean water, breathtaking vistas, mountains for skiing, rivers for fishing, oceans for sailing, sunsets for poets, and landscapes for painters. What good is it to have wind-powered lights to brighten the night if you can't see anything green during the day? Just because we can't sell shares in nature doesn't mean it has no value.”

“In my world, you don’t get to call yourself “pro-life” and be against common-sense gun control — like banning public access to the kind of semiautomatic assault rifle, designed for warfare, that was used recently in a Colorado theater. You don’t get to call yourself “pro-life” and want to shut down the Environmental Protection Agency, which ensures clean air and clean water, prevents childhood asthma, preserves biodiversity and combats climate change that could disrupt every life on the planet. You don’t get to call yourself “pro-life” and oppose programs like Head Start that provide basic education, health and nutrition for the most disadvantaged children...The term “pro-life” should be a shorthand for respect for the sanctity of life. But I will not let that label apply to people for whom sanctity for life begins at conception and ends at birth. What about the rest of life? Respect for the sanctity of life, if you believe that it begins at conception, cannot end at birth.”

“Some would ask what country am I from? We ara supposed to tell the truth, [so] we tell them India. Some thought it was Indiana, not India! Some did not know where India is. I said the country next to Pakistan.”

“No matter what your profession – doctor, lawyer, architect, accountant – if you are an American, you better be good at the touchy-feely service stuff, because anything that can be digitized can be outsourced to either the smartest or the cheapest producer.”

“You can be a rich person alone. You can be a smart person alone. But you cannot be a complete person alone. For that you must be part of, and rooted in, an olive grove. This truth was once beautifully conveyed by Rabbi Harold S. Kushner in his interpretation of a scene from Gabriel García Márquez’s classic novel One Hundred Years of Solitude: Márquez tells of a village where people were afflicted with a strange plague of forgetfulness, a kind of contagious amnesia. Starting with the oldest inhabitants and working its way through the population, the plague causes people to forget the names of even the most common everyday objects. One young man, still unaffected, tries to limit the damage by putting labels on everything. “This is a table,” “This is a window,” “This is a cow; it has to be milked every morning.” And at the entrance to the town, on the main road, he puts up two large signs. One reads “The name of our village is Macondo,” and the larger one reads “God exists.” The message I get from that story is that we can, and probably will, forget most of what we have learned in life—the math, the history, the chemical formulas, the address and phone number of the first house we lived in when we got married—and all that forgetting will do us no harm. But if we forget whom we belong to, and if we forget that there is a God, something profoundly human in us will be lost.”
