We should expect our theories to contain mistakes. Problems with constructor theory may sooner or later be discovered, which will require an even better/deeper explanation. There are no “final” theories.

As an individual’s knowledge grows, so does the amount of information he can use to create new explanations. Therefore, I would expect his creation of new knowledge to get slower over time. Yet we don’t seem to observe that. How can we explain that?

I like the emphasis on conjectures and refutations. Yet sometimes in interviews you say that we should consider something false until proven true. How do you reconcile these two approaches? (The difference being that conjectures in the Popperian sense can never be proven true.)

5/5 And each time this is done through conjecture and criticism. And then the cycle continues. Does this not seem Popperian? If it is, it seems to me we have made at least some headway in trying to code up AGI, but we'd need to do it for more than just mathematical problems.

@dchackethal · · Show · Open on Twitter

@DavidDeutschOxf

4/5 In this example, the first problem is "We don't have an explanation for how the planets move", to which the conjectured explanation is Kepler's laws. The second problem is the observation that they're not accurate enough, and so the laws are improved, etc.

@dchackethal · · Show · Open on Twitter

@DavidDeutschOxf

3/5 Then, if there is a problematic observation (problematic = it cannot be derived from Kepler's laws, such as a planetary position that does not fit the model), then the symbolic regression runs again given the problem, and it may find better explanations than Kepler's.

@dchackethal · · Show · Open on Twitter

@DavidDeutschOxf

2/5 What I mean is, eg, symbolic regression can find Kepler's laws given data about planetary positions etc. And it does so through conjecture and criticism, since it's a genetic algorithm. I think John Koza may actually have done this for Kepler's third law, but I'm not sure.

In the "Logic of Scientific Discovery" chapter 1 section 2, Popper conjectures that intuition plays an important role in coming up with new explanations (creativity). He also quotes Einstein as corroborating this in his address at Planck's 60th birthday.

Instead, he describes the process of conjecture and criticism by which theories can be dismissed. Surviving theories are nonetheless unlikely to be true. That likelihood does not improve with more failed tests. (See Logic of Scientific Discovery, Popper, 1934) 2/2
