Some key comments:
On asteroid risks:
"Certainly the danger from asteroid impacts is real, and certainly it makes sense to study ways of deflecting asteroids when the opportunity arises. But I find much of the rhetoric about asteroid impacts to be exaggerated. It seems likely that the real dangers to the survival of the biosphere come more from inside the earth than from outside."
Our long term human survival:
"My optimism about the long-term survival of life comes mainly from imagining what will happen when life escapes from this planet and becomes adapted to living in vacuum. There is then no real barrier to stop life from spreading through the universe. Hopping from one world to another will be about as easy as hopping from one island in the Pacific to another. And then life will diversify to fill the infinite variety of ecological niches in the universe, as it has done already on this planet. If you want an intellectual principle to give this picture a philosophical name, you can call it “The Principle of Maximum Diversity".
On the state of science:
"Certainly the growing rigidity of scientific organizations is a real and serious problem."
Global warming:
"I am always happy to be in the minority. Concerning the climate models, I know enough of the details to be sure that they are unreliable. They are full of fudge factors that are fitted to the existing climate, so the models more or less agree with the observed data. But there is no reason to believe that the same fudge factors would give the right behavior in a world with different chemistry, for example in a world with increased CO2 in the atmosphere."
Optimism:
"It is true that the tradition of Judeo-Christian religion is strongly coupled with philosophical optimism. Hope is high on the list of virtues. God did not put us here on earth to moan and groan. As my mother used to say, "God helps those who help themselves".
"I am generally optimistic because our human heritage seems to have equipped us very well for dealing with challenges, from ice-ages and cave-bears to diseases and over-population. The whole species did cooperate to eliminate small-pox, and the women of Mexico did reduce their average family size from seven to two and a half in fifty years. Science has helped us to understand challenges and also to defeat them."
Academia:
"The academics are suffering from business envy, in the USA as well as in Britain. .... The academics preaching doom and gloom are indeed hoping to take their revenge on the business community by capturing the government."
Religion - U.K. & U.S.A.
"The extremes of religious dogmatism in the USA and of atheistic dogmatism in Britain are greatly exaggerated by the media. In both countries, the average atheist and the average Christian are not dogmatic or unreasonable. So far as I can see, there is about the same variety of beliefs on both sides of the ocean. Certainly we do not need any accurate navigation to find a middle way between the two extremes. Probably ninety percent of the population are somewhere in the middle."
Intelligent Design
"My opinion is that most people believe in intelligent design as a reasonable explanation of the universe, and this belief is entirely compatible with science. So it is unwise for scientists to make a big fight against the idea of intelligent design. The fight should be only for the freedom of teachers to teach science as they see fit, independent of political or religious control. It should be a fight for intellectual freedom, not a fight for science against religion."
