Daniel Dennett

The juvenile sea squirt wanders through the sea searching for a suitable rock or hunk of coral to cling to and make its home for life. For this task, it has a rudimentary nervous system. When it finds its spot and takes root, it doesn't need its brain anymore, so it eats it! It's rather like getting tenure.
―Daniel C. Dennett

If you can approach the world’s complexities, both its glories and its horrors, with an attitude of humble curiosity, acknowledging that however deeply you have seen, you have only just scratched the surface, you will find worlds within worlds, beauties you could not heretofore imagine, and your own mundane preoccupations will shrink to proper size, not all that important in the greater scheme of things.
―Daniel C. Dennett, Breaking the Spell: Religion as a Natural Phenomenon

Every living thing is, from the cosmic perspective, incredibly lucky simply to be alive. Most, 90 percent and more, of all the organisms that have ever lived have died without viable offspring, but not a single one of your ancestors, going back to the dawn of life on Earth, suffered that normal misfortune. You spring from an unbroken line of winners going back millions of generations, and those winners were, in every generation, the luckiest of the lucky, one out of a thousand or even a million. So however unlucky you may be on some occasion today, your presence on the planet testifies to the role luck has played in your past.

Not a single one of the cells that compose you knows who you are, or cares.

If I know better than you know what I am up to, it is only because I spend more time with myself than you do.

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.
