Now it was possible to form planets, bacteria dinosaurs and us! Where did all these exotic new things come from? How do new things, new qualities ‘emerge’? Were they present in the components from which they were made? The simplest reductive arguments presume that they had to be. But if so, they can be devilishly hard to find. Can you find ‘wateriness’ in the atoms of hydrogen and oxygen that form water molecules? This is why ‘emergence’ so often seems magical and mysterious. But it’s not, really. One of the most beautiful explanations of emergence that I know can be found in a Buddhist sutra that was probably composed David Christian more than 2,000 years ago: “The Questions of Milinda”. (I’m paraphrasing on the basis of an online translation). would it still be a chariot?” “Yes, of course it would,” says Milinda with some irritation, wondering where Milinda is a great emperor. He was actually a this conversation is going. “And if you removed historical figure, the Greco-Bactrian emperor, the framework, or the flag-staff, or the yoke, or the Menander, who ruled a Central Asian kingdom reins, or the goad stick, would it still be a chariot?” founded by generals from Alexander the Great’s Eventually Milinda starts to get it. He admits that at army. In the sutra, Milinda meets with Nagasena, some point his chariot would no longer be a chariot a great Buddhist sage. They probably met in the because it would have lost the quality of ‘chariotness’ plains of modern Afghanistan, over 2,000 years ago. and could no longer do what chariots do. Milinda had summoned Nagasena because he was getting interested in Buddhism, but was puzzled And now, Nagasena cannot resist gloating because because the Buddha seemed to deny the reality of the Milinda has failed to define in what exact sense his ‘self’. Yet for most of us, the sense of self is the very chariot really exists. Then comes the punch line: bedrock of reality. (When Descartes said “I think, “Your Majesty has spoken well about the chariot. It is therefore I am”, I think he meant something like: just so with me. … This denomination ‘Nagasena,’ is “The self is the only thing we know that exists for a mere name. In ultimate reality this person cannot be certain.”) apprehended.” So we should imagine Milinda sitting in a royal Or, in modern language, I, and all the complex things chariot, followed by a huge retinue of courtiers around me, exist only because many things were and soldiers, meeting Nagasena, with his retinue of assembled in a very precise way. The ‘emergent’ Buddhist monks for a great debate about the nature properties are not magical. They are really there of the self, reality and creativity. It’s a splendid and eventually they may start re-arranging the vision. environments that generated them. But they don’t exist ‘in’ the bits and pieces that made them; they Milinda asks Nagasena to explain the Buddha’s idea emerge from the arrangement of those bits and pieces of the ‘self’. Nagasena asks: “Sire, how did you in very precise ways. And that is also true of the come here?” Milinda says: “In a chariot, of course, emergent entities known as “you” and “me”. reverend Sire!” “Sire, if you removed the wheels IBHA Members’ Newsletter Page 2 Volume II, Number 2 Stone Age Institute continued – essentially, ten “Top Ten” lists.

They have also written and recorded (with a number of world-class musicians) several songs about Big History and human evolution, which can be listened to and downloaded on the web site. This semester, Toth and Schick will be teaching a Big History course with Walter Alvarez at Indiana University entitled “Origins and Extinctions: The Big History of the Earth.” Walter will be their Distinguished Wells Visiting Professor at Indiana University and will be a part of a panel discussion with the Origins faculty working group, and will also host a public lecture by Walter on Big History.
