To reduce the interpretation of the causality of all kinds of climate changes and of global warming to one variable, CO2, or to a small proportion of one variable - human-induced CO2 - is impossible to accept. Elementary rationality and my decades-long experience with econometric modelling and statistical testing of scientific hypotheses tell me that it is impossible to make strong conclusions based on mere correlation of two (or more) time series.

Human relations tend to be more difficult when you're dealing with someone who weighs 30 kilograms more than you do. That's when you worry about whether a well-meaning gesture could produce complications. We have no problems with countries like Madagascar or Bolivia, for example. But Germany is our neighbor and we have a shared past. Besides, Germany is powerful and ambitious and more than four times as large as we are. It makes complete sense that we would act cautiously. It's simply Realpolitik.

And finally, there is another danger: the emergence of nonideological but very aggressive 'isms,' which are really quite new. Let me at least name them: We all care about human rights, but I am afraid of 'human rightism.' We all want to have a healthy environment, but I see the danger in environmentalism. To put it politically correctly, I admire the second gender, but I fear feminism. We all are enriched by other cultures, but not by multiculturalism. I am aware of the importance of voluntary associations, but I fear NGOism.

This is crossing the Rubicon, after which there will be no more sovereign states in Europe with fully-fledged governments and parliaments which represent legitimate interests of their citizens, but only one State will remain. Basic things will be decided by a remote 'federal government' in Brussels and, for example, Czech citizens will be only a tiny particle whose voice and influence will be almost zero. ... We are against a European superstate.

The largest threat to freedom, democracy, the market economy and prosperity, is no longer socialism. It is, instead, the ambitious, arrogant, unscrupulous ideology of environmentalism.

Common foreign policy is completely unnecessary. The various European countries have widely differing priorities, goals and prejudices. It would be wrong to force them all to follow the same course.

My main concern is the political dimension of European integration. This is one of the most important issues of all, as far as I'm concerned. It has to do with our past, with our sensitivity, perhaps even our hypersensitivity in this regard.
