“A number of years ago, when I was a freshly-appointed instructor, I met, for the first time, a certain eminent historian of science. At the time I could only regard him with tolerant condescension.I was sorry of the man who, it seemed to me, was forced to hover about the edges of science. He was compelled to shiver endlessly in the outskirts, getting only feeble warmth from the distant sun of science- in-progress; while I, just beginning my research, was bathed in the heady liquid heat up at the very center of the glow.In a lifetime of being wrong at many a point, I was never more wrong. It was I, not he, who was wandering in the periphery. It was he, not I, who lived in the blaze.I had fallen victim to the fallacy of the 'growing edge;' the belief that only the very frontier of scientific advance counted; that everything that had been left behind by that advance was faded and dead.But is that true? Because a tree in spring buds and comes greenly into leaf, are those leaves therefore the tree? If the newborn twigs and their leaves were all that existed, they would form a vague halo of green suspended in mid-air, but surely that is not the tree. The leaves, by themselves, are no more than trivial fluttering decoration. It is the trunk and limbs that give the tree its grandeur and the leaves themselves their meaning.There is not a discovery in science, however revolutionary, however sparkling with insight, that does not arise out of what went before. 'If I have seen further than other men,' said Isaac Newton, 'it is because I have stood on the shoulders of giants.”

“His eyes sparkled again, and in that instant I felt a strong urge to get up and leave him behind. I had been wrong to think what Sean and I had was special. He wasn’t ‘the one’. He couldn’t be. ‘The one’ would never leave me behind.”

“I don't view it as mystic. I believe that God is our father. He created us. He is powerful because he knows everything. Therefore everything I learn that is true makes me more like my father in heaven. When science seems to contradict religion, then one, the other, or both are wrong, or incomplete. Truth is not incompatible with itself. When I benefit from science it's actually not correct for me to say it resulted from science and not from God. They work in concert.”

“I like trees because they seem more resigned to the way they have to live than other things do. I feel as if this tree knows everything I ever think of when I sit here. When I come back to it, I never have to remind it of anything; I begin just where I left off.”

“As he rose to his feet he noticed that he was neither dripping nor panting for breath as anyone would expect after being under water. His clothes were perfectly dry. He was standing by the edge of a small pool—not more than ten feet from side to side in a wood. The trees grew close together and were so leafy that he could get no glimpse of the sky. All the light was green light that came through the leaves: but there must have been a very strong sun overhead, for this green daylight was bright and warm. It was the quietest wood you could possibly imagine. There were no birds, no insects, no animals, and no wind. You could almost feel the trees growing. The pool he had just got out of was not the only pool. There were dozens of others—a pool every few yards as far as his eyes could reach. You could almost feel the trees drinking the water up with their roots. This wood was very much alive.”

“A botanist would have been stumped, coming across a tree like this one. Yet, if we are to judge a tree by its fruit, it was clearly an avocado. I picked the fruit, sliced it open, and tasted it to make sure. There was no doubt in my mind. If it looks like an avocado and tastes like an avocado, it has got to be an avocado. However, the tree itself had a white bark like that of a birch and its sap tasted like birch juice. Its leaves were delicate like that of a cypress, while its trunk and the root system reminded me of a baobab. Could it be that someone had grafted an avocado on to a baobab tree? And if so, why the bark so white and the leaves so, well, feathery, and delicate yet bold like a dragonfly’s wing? Why is there not another tree like it nearby? Where had the seed of this tree come from? I had no answer. So, I put the seed of the fruit in my pocket and took it home with me to see if I could make it grow.”
