Obviously, a man's judgement cannot be better than the information on which he has based it. Give him the truth and he may still go wrong when he has the chance to be right, but give him no news or present him only with distorted and incomplete data, with ignorant, sloppy or biased reporting, with propaganda and deliberate falsehoods, and you destroy his whole reasoning processes, and make him something less than a man.
Like in the paintings, there has to be moments that are completely right to be able to feel how wrong it is when the space gets flattened or the space collapses. It's the same with the technique in the sculptures: for some to feel really wrong, you have to have parts be really right.
