“At the end of this exercise, you’ll have a tree and it will have you. You can measure it monthly and chart your own growth curve. Every day, you can look at your tree, watch what it does, and try to see the world from its perspective. Stretch your imagination until it hurts: What is your tree trying to do? What does it wish for? What does it care about? Make a guess. Say it out loud. Tell your friend about your tree; tell your neighbor. Wonder if you are right. Go back the next day and reconsider. Take a photograph. Count the leaves. Guess again. Say it out loud. Write it down. Tell the guy at the coffee shop; tell your boss. Go”

“Don’t be fooled by the few red or brown leaves you find on poison ivy in the fall—the plant is not dying; it’s just cheating with different pigments.”

“The leaves of the world comprise countless billion elaborations of a single, simple machine designed for one job only – a job upon which hinges humankind. Leaves make sugar. Plants are the only things in the universe that can make sugar out of nonliving inorganic matter. All the sugar that you have ever eaten was first made within a leaf. Without a constant supply of glucose to your brain, you will die. Period. Under duress, your liver can make glucose out of protein or fat – but that protein or fat was originally constructed from a plant sugar within some other animal. It’s inescapable: at this very moment, within the synapses of your brain, leaves are fueling thoughts of leaves.”

“You probably have a bathroom scale that can tell the difference between a 180-pound man and a 185-pound man. I have a scientific scale that can tell the difference between an atom with twelve neutrons and an atom with thirteen neutrons. Actually, I have two such scales. They are called mass spectrometers, and they are worth about half a million dollars each.”
