Attention and precaution have subsided, which especially the EU integration process shows, Klaus writes.
At present, almost no one in Europe and the USA is ashamed to introduce measures that were once definitively discredited and that ended along with the end of communism, Klaus writes.
Klaus is a well-known critic of the EU developments. In his book he assesses the 23 years that have elapsed since the fall of the Iron Curtain.
The book are no memoirs, however. According to Klaus, it expresses his "certain disappointment" at what not only the Czech Republic but also the whole present world look like.
"When I compare the present world with what it seemed to be at the time of the fall of communism and within all the expectations we had then, I must say the [present] world is worse," Klaus said.
The world is less free than in the past, he added.
He said when writing the book he borrowed, for example, the words philosopher Jose Ortega y Gasset used after the end of World War One.
"We find ourselves in a similar crisis moment of our European and world history as was the one Ortega described along with what he viewed as the twilight of the Western Civilisation," Klaus said.
Klaus has written on his website that he "must state, though not with pleasure, that the world he lives in now is much more socialist, if not communist, and by all means more unfree than he imagined then, at the time of the initial vigour and enthusiasm" after the late 1989 fall of communism in the then Czechoslovakia.
"This feeling of disappointment I have, or the defence and explanation of my present feeling, is the book's objective. At the same time it indicates why the book has been written," Klaus writes.
He says the book tries to "track" the key and breakthrough moments of the [post-1989] period that contributed to the present situation, and indicates what path should be taken now.
Klaus, whose second and last possible mandate expires on March 7, also plans to issue another of his annual books mapping his past year as president in the days to come.
The book presentation at Prague Castle Wednesday was also attended by politicians, including Justice Minister Pavel Blazek (for Civic Democrats, ODS, a party Klaus founded and headed in the 1990s), some senators, former ODS MP Vlastimil Tlusty and extra-parliamentary Sovereignty party chairwoman and former MEP Jana Bobosikova, known for her Euro scepticism close to Klaus's.
