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

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.

Feeling insignificant because the universe is large has exactly the same logic as feeling inadequate for not being a cow.

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

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

Every problem that is interesting is also soluble.

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.

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.

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.

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

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.

A person who is too proud in love will suffer from the devastating bitterness in the end.

Don’t focus on outward means of satisfaction if you want to be happy.

If your freedom means immorality, the cross will cry over your freedom.

Justice is the sum of all moral duty.

I wanted to have the opportunity to travel to Vietnam and Sydney, and have the chance to work there.

This is normal, to have pressure. It's how you respond. Take the pressure, use the pressure, have fun.

I don't have time to distinguish between the unfortunate and the incompetent.

Well, since I produce and pay for my own albums, it is the ultimate freedom.

I would like to see the Iraqi government guarantee social insurance for the Yazidi women who were enslaved and to recognise their status as prisoners of war.
