James Burke (science historian)

... That's all it takes to get you back to the late 18th century. Three grandfather's lifetimes. That's how close we are to it. And, yet, that world has disappeared so totally, it's like fairyland. Thatched cottages, meadows, happy peasants. A golden age. Garbage, all that. Nasty, brutish, and short - that's what life was all about. And dirty. And boring. And it had been like that for thousands of years! And then, suddenly, the whole complex polluted overpopulated phrenetic nonstop stressful high tech rat race that is the modern world... Life was suddenly no longer as simple as it had been. And the extraordinary thing is, none of that was planned.

I would say it was a pretty safe bet, that the one magic wish most people would like to be granted would be to be able to see into the future. Think what it would mean. And backing the right horse! But we can't. We have to guess about tomorrow and we have to act on that guess, and it's never been any different. And that's why following the trail from the past up to the emergence of the modern technology that surrounds us in our daily lives, and affects our lives, is rather like a detective story. Because, at no time in the past, did anybody have anything to do with the business of inventing or changing things, ever know what the full effect of his actions would be. He just went ahead and did what he did for his own reasons, like we do. That's how change comes about. And it's like a detective story because if you follow the trail from the past up to a modern man-made object, the story is full of sudden twists and false clues and guesswork, and you never know where the story is heading until the very last minute.

Today, the nuclear bomb is like a Sword of Damocles hanging over us. Will it fall again?

Edison invented inventing.

The oldest answers to the most basic questions about how to operate are common to virtually every culture on the planet, because at the simplest level, every culture needs to keep order -- especially this kind: (James Burke displays a wedding ring.) This is one of those things in life we protect most against being changed when knowledge changes us. We protect it by turning it into a ritual. When we get married, or buried, get christened, or anything else too important to play by ear, the event is turned into a kind of play where everybody gets a role they act out. It's a kind of public agreement to stick to the general rules about whatever it is. The people doing it are effectively saying, "No matter what else may change, we won't rock the boat! We're not maverick. You can trust us." Expressions of approval follow. Most of these ritual ways of answering a social need that we got from the past look like it. They include something from an ancient rite -- in this case, the old symbol of fertility: the ring. And then, it's all done in the presence of a supernatural being: a God. So, the agreement is also made under what was once a real threat of heavenly retribution if you broke your promise later on. Some things, this ritual says, must be permanent.

Does the cycle that goes, interest in something, involvement in it, tiring of it, and rejection of it, looking into something else, get shorter every decade?

The Egyptians built an empire and ran it with a handful of technology... the wheel, irrigation canals, the loom, the calendar, pen & ink, some cutting tools, some simple metallurgy, and the plough, the invention that triggered it all off. And yet look how complex and sophisticated their civilisation was. And how soon it happened, after that first man-made harvest. The Egyptian plough and those of the few other civilisations sprang up around the world at the same time... Gave us control over nature... And at the same time, tied us for good, to the things that we invent so that tomorrow will be better than today. The Egyptians knew that. That's why they had gods. To make sure that their systems didn't fail.
