Textele publicate în acest volum îl fac pe cititor părtaş la două evenimente ale anului 1983, care au stârnit senzaţie. În februarie 1983, doi renumiţi oameni de ştiinţă s-au întâlnit la Altenberg, în Viena. Karl R. Popper, teoretician al ştiinţei şi filosof şi Konrad Lorenz, medic, zoolog şi cercetător al comportamentelor au discutat despre munca lor ştiinţifică, despre interpretarea rezultatelor obţinute şi despre convingerile lor filosofice. Tema centrală a fost: Ce ştim despre viitor? Suntem profeţi? Lorenz pesimistul optimist şi Popper, interpretul
Sir Karl Raimund Popper, FRS, rose from a modest background as an assistant cabinet maker and school teacher to become one of the most influential theorists and leading philosophers. Popper commanded international audiences and conversation with him was an intellectual adventure—even if a little rough—animated by a myriad of philosophical problems. He contributed to a field of thought encompassing (among others) political theory, quantum mechanics, logic, scientific method and evolutionary theory.
Popper challenged some of the ruling orthodoxies of philosophy: logical positivism, Marxism, determinism and linguistic philosophy. He argued that there are no subject matters but only problems and our desire to solve them. He said that scientific theories cannot be verified but only tentatively refuted, and that the best philosophy is about profound problems, not word meanings. Isaiah Berlin rightly said that Popper produced one of the most devastating refutations of Marxism. Through his ideas Popper promoted a critical ethos, a world in which the give and take of debate is highly esteemed in the precept that we are all infinitely ignorant, that we differ only in the little bits of knowledge that we do have, and that with some co-operative effort we may get nearer to the truth.
Nearly every first-year philosophy student knows that Popper regarded his solutions to the problems of induction and the demarcation of science from pseudo-science as his greatest contributions. He is less known for the problems of verisimilitude, of probability (a life-long love of his), and of the relationship between the mind and body.
Popper was a Fellow of the Royal Society, Fellow of the British Academy, and Membre de I'Institute de France. He was an Honorary member of the Harvard Chapter of Phi Beta Kappa, and an Honorary Fellow of the London School of Economics, King's College London, and of Darwin College Cambridge. He was awarded prizes and honours throughout the world, including the Austrian Grand Decoration of Honour in Gold, the Lippincott Award of the American Political Science Association, and the Sonning Prize for merit in work which had furthered European civilization.
Karl Popper was knighted by Queen Elizabeth II in 1965 and invested by her with the Insignia of a Companion of Honour in 1982.
Conhecer o pensamento de Karl Popper é fundamental para falar sobre a Democracia. Este livro já tem sublinhados desde a 1ª vez que o li, e gosto de o manter por perto. É um antídoto contra a mentalidade pessimista com a qual nos deparamos diariamente. Em forma de uma conversa e um simpósio, aborda os temas da igualdade, liberdade, democracia. O papel do pensamento crítico e do rigor científico na evolução humana, na educação e na cidadania.
"Il vero momento della libertà sta nella indeterminatezza."
Metafisica del linguaggio e problema della conoscenza, razionalismo critico, società chiusa e società aperta, e fallibilità del metodo scientifico sono solo alcuni temi di questa raccolta di scritti brevi di alcuni dei maggiori pensatori austriaci del nostro tempo.
