It is possible to build a virtual-reality generator whose repertoire includes every possible environment.

The overwhelming majority of theories are rejected because they contain bad explanations, not because they fail experimental tests.

Our best theories are not only truer than common sense, they make more sense than common sense...

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.

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.

Discovering a new explanation is inherently an act of creativity.

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.
