“There are little wisps of jelly in a living brain. Deagle knows this well: neurons, transmitting signals - and the soul, so to speak, is somewhere in those flashes. He heard once on a science program that the spindle cell - present in humans, whales, some apes, elephants - may be at the heart of what we call our "selves."What we recognize in the mirror - that thread we follow through time that we call "me"? It's just a diatom, a paramecium, a bit of ganglia that branches and shudders assertively. A brief brain orgasm, like lightning.In short, it's all chemicals. You can regiment it easily enough: fluoxetine, sertraline, paroxetine, escitalopram, citalopram - the brain can be washed clean, and you can reset yourself, Ctrl+Alt+Del. You don't have to be a prisoner of your memories and emotions.”

“Who knows what I want to do? Who knows what anyone wants to do? How can you be sure about something like that? Isn't it all a question of brain chemistry, signals going back and forth, electrical energy in the cortex? How do you know whether something is really what you want to do or just some kind of nerve impulse in the brain? Some minor little activity takes place somewhere in this unimportant place in one of the brain hemispheres and suddenly I want to go to Montana or I don't want to go to Montana. How do I know I really want to go and it isn't just some neurons firing or something? Maybe it's just an accidental flash in the medulla and suddenly there I am in Montana and I find out I really didn't want to go there in the first place. I can't control what happens in my brain, so how can I be sure what I want to do ten seconds from now, much less Montana next summer? It's all this activity in the brain and you don't know what's you as a person and what's some neuron that just happens to fire or just happens to misfire.”

“Some years ago, there was a lovely philosopher of science and journalist in Italy named Giulio Giorello, and he did an interview with me. And I don’t know if he wrote it or not, but the headline in Corriere della Sera when it was published was "Sì, abbiamo un'anima. Ma è fatta di tanti piccoli robot – "Yes, we have a soul, but it’s made of lots of tiny robots." And I thought, exactly. That’s the view. Yes, we have a soul, but in what sense? In the sense that our brains, unlike the brains even of dogs and cats and chimpanzees and dolphins, our brains have functional structures that give our brains powers that no other brains have - powers of look-ahead, primarily. We can understand our position in the world, we can see the future, we can understand where we came from. We know that we’re here. No buffalo knows it’s a buffalo, but we jolly well know that we’re members of Homo sapiens, and it’s the knowledge that we have and the can-do, our capacity to think ahead and to reflect and to evaluate and to evaluate our evaluations, and evaluate the grounds for our evaluations.It’s this expandable capacity to represent reasons that we have that gives us a soul. But what’s it made of? It’s made of neurons. It’s made of lots of tiny robots. And we can actually explain the structure and operation of that kind of soul, whereas an eternal, immortal, immaterial soul is just a metaphysical rug under which you sweep your embarrassment for not having any explanation.”

“First, we cannot overload the human brain. This divinely created brain has fourteen billion cells. If used to the maximum, this human computer inside our heads could contain all the knowledge of humanity from the beginning of the world to the present and still have room left over. Second, not only can we not overload our brain - we also know that our brain retains everything. I often use saying that "The brain acquires everything that we encounter." The difficulty does not come with the input of information, but getting it out. Sometimes we "file" information randomly of little importance, and it confuses us.”

“The teacher did say we can help one another. Cooperative learning it's called. That's where you borrow someone else's brain because yours isn't big enough.”

“Most people think love comes from the heart or soul. The heart simple pumps blood, so love can't be created there. Where is the center for what appears to be a persons soul? The brain. And what is created there Jilly? That's right-dopamine. What does dopamine do? creates feelings of love and euphoria. How do we get our brains to create more? Drugs, massage, and or sex. Boil it down and it's all just dopamine. The good news is that you can also get more dopamine pumping through your brain by skiing fast...”
