For Man nothing is beyond doubt; for God everything is beyond doubt.

The best thing about the world is that it has a mysterious structure and the worst thing is that it has a grievous structure.

I have far more reasons to rather disbelieve that a man besides me suffers when he cries, yet I have far more sentiments, than those great reasons, to instead weep for his, far less likely, sufferings.

There is only one real computer - the universe - whose hardware is made up of non-spatial states of consciousness and software is made up of superhuman as well as non-superhuman thoughts.

The difference between religion and science is the difference between thoughtless certainty and thoughtful doubt.

I am convinced that an electronic machine, no matter how smart and intelligent, being still a mere spatial structure in concept, can neither innovate nor even understand the self-evident proposition: 'No spatial structure can be a representation of any feeling'. Such innovation can only be a work of a non-spatial mind, like a human being, and only such innovation, it should be acknowledged, can pave the way for further scientific achievements.

The word philosophy, as distinguished from science, is misleading, for it implies that what philosophy contains is impossible to be a systematic body of knowledge and what science contains is certain or proved.
