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.

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.

What is concisely referred to as global warming, is a fatal mistake of the present time.

Then in 1969, I spent the spring term at Cornell University in New York. The invasion of August 1968 had already happened, but the hardline regime took several months to crack down on dissidents.

I also helped write the five-page statement of principles that Civic Forum issued in late November. That was the first public expression of what the new government wanted to do.

The development of European integration can be divided into two phases. The first era ended with the Maastricht Treaty. It was a liberalization phase, with the main goal of European integration at the time being the removal of various barriers and borders in Europe. The second phase is a homogenization or standardization phase, one that involves regulation from the top and growing control over our lives. This no longer has anything to do with freedom and democracy.

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.
