"Here is a conclusion I've come to after many years: among all the errors we may have committed, the greatest of them all was that we believed that someone really knew something about socialism, or that someone actually knew how to build socialism. It seemed to be a sure fact, as well-known as the electrical system conceived by those who thought they were experts in electrical systems. Whenever they said: “That’s the formula”, we thought they knew. Just as if someone is a physician. You are not going to debate anemia, or intestinal problems, or any other condition with a physician; nobody argues with the physician. You can think that he is a good doctor or a bad one, you can follow his advice or not, but you won't argue with him. Which of us would argue with a doctor, or a mathematician, or a historian, or an expert in literature or in any other subject? But we must be idiots if we think, for example, that economy is an exact and eternal science and that it existed since the days of Adam and Eve, and I offer my apologies to the thousands of economists in our country."
