John Gray is a professor of History who introduces the commentary speaking about the general thought of the economical crisis being part of the past and the situation being continuously getting better. Then he throws the rethorical question which would make the listener to keep tuned, curious: "Are we fooling oursevles?"
This professor distinguishes between things which are known but people do not pay attention to them, things that are not known and, finally, things which people do know but prefer to pretend to forget or ignore - i.e. things we choose not to know.
The first example is the Iraq war and the massive destruction weapons topic, which ended up to be just a justification. However, as Sadam was in some way linked to Al-Qaeda and the USA was expected to settle democracy in this country, no one has complained. The speech is not about what happned or did not happen, but about the fact that people rathers not to know, as it is more comfortable.
The second example is about the financial crisis and how, all along history, just before the crack everything was perfect. From a historical point of view, a crisis does not occur from day to night - there are many factors which indicate it and vaticcinates its advent long before it happens. However, people just ignores them, for it is easier to live in a not so realistic world.
As a conclusion, he suggests that it is the system itself which provokes this evading-minded people, as it is the only way it can work. And, although all crisis and tragedies are similar to others which have already happened, people rather to forget and ignore.
It is remarkable that John Gray appeals to examples which are common and known by everybody -in fact, he does not give any data, just opinion- but no one really knows concretely about them, not even experts. Thus, he contacts with the listener, making him believe that this reasoning could have been developed by him or her.
