David Deutsch Quotes


13 David Deutsch quotes:



"I myself believe that there will one day be time travel because when we find that something isn't forbidden by the over-arching laws of physics we usually eventually find a technological way of doing it."
"Every problem that is interesting is also soluble."

"Surely it is more interesting to argue about what the truth is, than about what some particular thinker, however great, did or did not think."
"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."

"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."
"It is possible to build a virtual-reality generator whose repertoire includes every possible environment."
"Is the human race a universal constructor?"
"Our best theories are not only truer than common sense, they make more sense than common sense."
"The theory of computation has traditionally been studied almost entirely in the abstract, as a topic in pure mathematics. This is to miss the point of it. Computers are physical objects, and computations are physical processes. What computers can or cannot compute is determined by the laws of physics alone, and not by pure mathematics."
"Necessary truth is merely the subject-matter of mathematics, not the reward we get for doing mathematics. The object of mathematics is not, and cannot be, mathematical certainty. It is not even mathematical truth, certain or otherwise. It is, and must be, mathematical explanation."
"Every potential angle is being looked at the same way as the previous crimes, ... We do have investigative leads."
