Einstein and Darwin: A tale of two theories

The trouble with evolution
Since evolution is an organizing principle of biology that allows you to understand phenomena, there are people who resist it.

Now the way I see it, that level of resistance is not fundamentally different from the resistance that prevailed when Copernicus and Galileo demonstrated that Earth goes around the sun and not vice versa. We didn’t have Newtonian gravity back then. You couldn’t predict, with high precision, the clockwork solar system. That would have been a new word back then: “solar system,” implying that the sun is at the center of things.

Back then, you had religious types arguing this, saying that it was against scripture, against God, against God’s way, God’s will. Back then, of course, the church was very powerful. They were basically the state in Italy. So there was the power to enforce a point of view, which made it bad for your health to espouse views that were different from people’s interpretation of scripture.

Today, I’m happy to report that they don’t burn people at the stake if they claim that Earth goes around the sun, or that there are other stars that might have other planets that themselves could have life. It’s statements like that that got Giordano Bruno burned at the stake in 1600, just 10 years before Galileo really came on the scene with his “Starry Messenger,” reporting that Jupiter had moons, which made Jupiter the center of that motion, and not Earth.

So things were changing rapidly back then, from burning Bruno at the stake, to putting Galileo under house arrest, to modern days, with the Catholic Church issuing statements saying evolution’s OK. So history has shown that some theistically based belief systems have been able to adapt to the prevailing discoveries of science. Those that don’t will be left behind. And if you’re left behind, you become disenfranchised from the forces that control emerging economies.

We’re in the 21st century. The emerging economies are going to be scientifically and technologically driven. We’re not agrarian anymore.

What were the consequences in the mid-1800s of saying you didn’t believe Darwin? There weren’t any, really. But today, with biotech companies, there is no understanding of biology without the theory of evolution. And so if you say, ‘I don’t believe the theory of evolution, I think we were all specially created,’ you must understand the consequences of it to your own employability.

Now if you don’t want to become a scientist, then maybe it doesn’t matter. Fine. There are plenty of professions that do not involve scientists. But as I said, the emergent economies are going to be scientifically and technologically driven, with biotech front and center. If you’re coming in saying that there was Adam and Eve, you’re not going to get past the front door. Because they can’t use your knowledge base to invent the next vaccine, the next medicine, the next cure for cancer. That knowledge base does not track into discoveries we know are awaiting us in the halls of biotech firms.

You’re saying that your perspective on those theories affects the pace of innovation?

Yes. And I would add this, just to nip this argument over “theories” in the bud: Until Einstein, all tested, confirmed physical theories were labeled laws. There’s Newton’s three laws of motion … the laws of gravity … the laws of thermodynamics. When Einstein came along, he showed that Newton was incomplete — not wrong, but incomplete, describing just a subset of reality. Einstein showed that a deeper understanding was required to account for this reality. At that point, physicists – I think not even consciously, just sort of subconsciously – stopped calling things “laws.”

There are no “laws” of physics in the 20th century. It’s quantum theory … the theory of relativity … you just look in the books, they all use the term “theory.” I think it’s a recognition that someone who comes after you may achieve an even deeper understanding of how things work. But “deeper” doesn’t mean that what you did is no longer valid. It just means that there’s a larger sphere of understanding that awaits you, in which what you just learned is embedded.

It’s like the old classical Venn diagram: Here’s the Newton universe. The Einstein universe is now that, enclosing Newton. Einstein’s equations look like Newton’s equations, when you put in low gravity and low speeds. They all reduce, and they’re identical to Newton’s equations. Because Newton’s equations work: They don’t suddenly fail to work in the regime in which they were demonstrated to work. They don’t become undone. They’re still there.

So now we know that general relativity is incomplete, because it doesn’t marry with quantum mechanics. They don’t talk to each other. We know that already. So now we are asserting that there’s yet an even bigger circle out there, that would include quantum mechanics with general relativity. And this is what the string theorists are doing. That’s what drives them. They’re not driven by some whim.

Right. It’s not a mere desire to come up with something esoteric.

They’re not doing this just for the hell of it. No. There’s a gap there. And that deeper understanding, like I said, is an understanding that encloses the previous understandings because they’ve already been demonstrated to work.

But the change in vocabulary is not received the same way by the public. They hear the word “theory” and they say, “Well, it’s only a theory. Tomorrow it could be different.” Well, if it’s different tomorrow, it’s because we’ve found something that’s even more powerful than this. It’s not because we looked and found something completely different over here.

Now, the word “theory” is also used to describe ideas that are very tentative. That’s true. So now we’re stuck with a problem: We’ve got evolutionary theory, quantum theory, all very well tested and very well established – and now we’ve got somebody’s theory on the frontier of the science, that will probably be shown to be wrong, because most fresh theories are wrong. But they keep you investigating. You’re hacking through the brush and bramble, trying to make a clearing where you understand what’s going on. There’s an unfortunate mismatch in the way scientists use the word “theory” and the public’s interpretation of the word, as applied to these century-old understandings of the world.

So that’s unfortunate. But what the public needs to understand is, there is nothing more powerful than successful theories. They organize ideas in ways that grant you a power of understanding that is without equal in any system of human thought that has ever come before.
