The modern mind tends to be more and more critical and analytical in spirit hence it must devise for itself an engine of expression which is logically defensible at every point and which tends to correspond to the rigorous spirit of modern science.

Science must begin with myths and with the criticism of myths.

It is critical to develop a biofuel industry powered by feedstocks produced in every corner of the country in addition to the Midwest. That is why USDA has established five regional research centers working on science necessary to ensure profitable biofuels can be produced from a diverse range of feedstocks.

Perhaps it would be better for science that all criticism should be avowed.

What I like about sceptics is that in good science you need critics that make you think: 'Crumbs have I made a mistake here?' If you don't have that continuously you really are up the creek. The good sceptics have done a good service but some of the mad ones I think have not done anyone any favours.

Individual science fiction stories may seem as trivial as ever to the blinder critics and philosophers of today - but the core of science fiction its essence has become crucial to our salvation if we are to be saved at all.

People say you should read your criticism because it will make you a better person but it doesn't. It just makes you a sad bitter old showbiz nightmare.

It's critical that the manager has the respect of players so he can make the moves that he feels is appropriate without having somebody go to the papers. They respect you. So you respect them back.

I learn something from criticism because when it comes from sources you respect you always examine it and learn.

I've been a critic of the antiglobalization movement and they've been a critic of me but the one thing I respect about the movement is their authentic energy. These are not people who don't care about the world.
