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.	Time, Travel	101
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.		102
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.	Technology	103
The brain is the only kind of object capable of understanding that the cosmos is even there, or why there are infinitely many prime numbers, or that apples fall because of the curvature of space-time, or that obeying its own inborn instincts can be morally wrong, or that it itself exists.		104
It is possible to build a virtual-reality generator whose repertoire includes every possible environment.		105
Our best theories are not only truer than common sense, they make more sense than common sense.		106
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.		107
The truly privileged theories are not the ones referring to any particular scale of size or complexity, nor the ones situated at any particular level of the predictive hierarchy, but the ones that contain the deepest explanations.		108
The overwhelming majority of theories are rejected because they contain bad explanations, not because they fail experimental tests.		109
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.	Travel	110
Is the human race a universal constructor?		111
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.		112
Where we have good, testable explanations, they then have to be tested, and we drop the ones that fail the tests.		113
Every problem that is interesting is also soluble.		114
Science is objective. And in my view we cannot take any experimental results seriously except in the light of good explanations of them.		115
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.		116
