“If, as the dowager had said, we are nothing but gene carriers, why do so many of us have to lead such strangely shaped lives? Wouldn’t our genetic purpose—to transmit DNA—be served just as well if we lived simple lives, not bothering our heads with a lot of extraneous thoughts, devoted entirely to preserving life and procreating? Did it benefit the genes in any way for us to lead such intricately warped, even bizarre, lives?”

“Walking to the subway, Aomame kept thinking about the strangeness of the world. If, as the dowager had said, we were nothing but gene carriers, why do so many of us have to lead such strangely shaped lives? Wouldn’t our genetic purpose – to transmit DNA – be served just as well if we lived simple lives, not bothering our heads with a lot of extraneous thoughts, devoted entirely to preserving life and procreating? Did it benefit the genes in any way for us to lead such intricately warped, even bizarre, lives?… how could it possibly profit the genes to have such people existing in this world? Did the genes merely enjoy such deformed episodes as colorful entertainment, or were these episodes utilized by them for some greater purpose?”

“Different sorts of survival machine appear very varied on the outside and in their internal organs. An octopus is nothing like a mouse, and both are quite different from an oak tree. Yet in their fundamental chemistry they are rather uniform, and, in particular, the replicators that they bear, the genes, are basically the same kind of molecule in all of us—from bacteria to elephants. We are all survival machines for the same kind of replicator—molecules called DNA— but there are many different ways of making a living in the world, and the replicators have built a vast range of machines to exploit them. A monkey is a machine that preserves genes up trees, a fish is a machine that preserves genes in the water; there is even a small worm that preserves genes in German beer mats. DNA works in mysterious ways.”

“Schwartz's research suggests something important: we can stretch our personalities, but only up to a point. Our inborn temperaments influence us, regardless of the lives we lead. A sizeable part of who we are is ordained by our genes, by our brains, by our nervous systems. And yet the elasticity that Schwartz found in some of the high-reactive teens also suggests the converse: we have free will and can use it to shape our personalities.”

“We live in times where the speed of our life is increasing but leading us nowhere.”

“You and I have been created with a DNA that drives us to want to live a life with good experiences, forces us to human growth and leads us to the contribution of something beyond our understanding.”
