David Deutsch Quotes

If you can’t program it, you haven’t understood it Picture Quote #1

The most important application of quantum computing in the future is likely to be a computer simulation of quantum systems, because that’s an application where we know for sure that quantum systems in general cannot be efficiently simulated on a classical computer Picture Quote #1

No precautions, and no precautionary principle, can avoid problems that we do not yet foresee. We need a stance of problem-fixing, not just problem-avoidance Picture Quote #1

The whole [scientific] process resembles biological evolution. A problem is like an ecological niche, and a theory is like a gene or a species which is being tested for viability in that niche Picture Quote #1

The quantum theory of parallel universes is not the problem, it is the solution. It is not some troublesome, optional interpretation emerging from arcane theoretical considerations. It is the explanation, the only one that is tenable, of a remarkable and counter-intuitive reality Picture Quote #1

Time travel may be achieved one day, or it may not. But if it is, it should not require any fundamental change in world-view, at least for those who broadly share the world view I am presenting in this book Picture Quote #1

Every problem that is interesting is also soluble Picture Quote #1

If we can’t program it, we can’t understand it Picture Quote #1

Discovering a new explanation is inherently an act of creativity Picture Quote #1

Humans may or may not have cosmic significance, and if they do, it will be by hitching a ride on the objective centrality of knowledge in the cosmic scheme of things Picture Quote #1

If you reject the infinite, you are stuck with the finite, and the finite is parochial... the best explanation of anything eventually involves universality, and therefore infinity. The reach of explanations cannot be limited by fiat Picture Quote #1

Science is objective. And in my view we cannot take any experimental results seriously except in the light of good explanations of them Picture Quote #1

To me quantum computation is a new and deeper and better way to understand the laws of physics, and hence understanding physical reality as a whole Picture Quote #1

Where we have good, testable explanations, they then have to be tested, and we drop the ones that fail the tests Picture Quote #1

I don’t think it would be a good idea for scientists to have more political power. Scientists as a group are more inclined to try to derive an ought from an is, than the population at large Picture Quote #1

The most important application of quantum computing in the future is likely to be a computer simulation of quantum systems, because that’s an application where we know for sure that quantum systems in general cannot be efficiently simulated on a classical computer Picture Quote #1

Base metals can be transmuted into gold by stars, and by intelligent beings who understand the processes that power stars, but by nothing else in the universe Picture Quote #1

Feeling insignificant because the universe is large has exactly the same logic as feeling inadequate for not being a cow Picture Quote #1

Like every other destruction of optimism, whether in a whole civilisation or in a single individual, these must have been unspeakable catastrophes for those who had dared to expect progress. But we should feel more than sympathy for those people. We should take it personally. For if any of those earlier experiments in optimism had succeeded, our species would be exploring the stars by now, and you and I would be immortal Picture Quote #1

The overwhelming majority of theories are rejected because they contain bad explanations, not because they fail experimental tests Picture Quote #1

Our best theories are not only truer than common sense, they make more sense than common sense Picture Quote #1

Quantum computation is... a distinctively new way of harnessing nature... It will be the first technology that allows useful tasks to be performed in collaboration between parallel universes Picture Quote #1
