“For a man to know what he has when he had it, that is what makes him a fortunate man.”

“He doesn’t know to want for more because nothing in his life has been as much as this...on that night he thinks that no one has ever had so much and only later will he know he should have asked for more.”

“But these last months had turned him around and now Gen saw there could be as much virtue in letting go of what you knew as there had ever been in gathering new information. He worked as hard at forgetting as he had ever worked to learn.”

“Instead, he was astonished by what he had: the chance to sit beside this woman in the late afternoon light while she read.”

“He used to say we all had a compass inside of us and what we needed to do was to find it and to follow it.”

“I saw it myself. An endless succession of mongrels and malingerers, the laziest dropouts who fancied themselves explorers. He made his policy clear: he was not responsible for their food, their shelter, their safety, or their health. He didn't waste his time discouraging them because frankly there was no discouragement they could not withstand. All of the energy they could have put into their intelligence they had used to develop their tenacity. But what I quickly learned was that their tenacity was for going, not for staying. Once they were out on the trail they fell like flies. Some took a day, two days, others were gone in a matter of hours, and Dr. Rapp never stopped for them. He remained beautifully consistent: he was to work and he would continue to work. He would not ferry back the weak and the lame. They had chosen to get themselves in and they would simply have to figure the means to get themselves out. People were quick to accept these terms until they themselves were weak. Then they changed their tune entirely, then they said Dr. Rapp was heartless. They couldn't slander him as a scientist but they said no end of scurrilous things about him as a man. He hadn't rescued them! He hadn't been their father and mother! I will tell you, none of that troubled his sleep. If he had made them his responsibility, either by dissuading them from their ambitions or by bailing them out of their folly, the greatest botanist of our time would have been reduced to a babysitter. It would have been an incalculable blow to science, all in the name of saving the stupid.”

“Shy Carmen, always hanging back from the others, who knew she could smile? But at the sight of that smile he would have promised her anything. He was just barely awake. Or maybe he was not awake at all. Had he wanted her and not known it? Had he wanted her so much that he dreamed she was lying beside him now? The things our minds keep from us, Gen thought. The secrets we keep even from ourselves.”
