Taleb`s main idea, is that we do not live in a linear world. Many people prefer to believe, that we do live in a linear world. In fact, it is a much more comforting way to go through life. The idea of not being able to fully comprehend a particular subject, is rejected by a lot of people. Most of the time, people search for a simple black and white answer. Taleb wishes to challenge readers into, "having the guts to admit, they just don`t know". Yes there are ideas out there, that are beyond our current understanding.
Talib labels these surprise revaluations;Black Swans. These are game changing ideas. Things that in the past, could never be considered possible.
Talib lists all sorts of examples of Black Swans. Most of the examples, will make for very good reading.
This was a very interesting book. Talib however, does have some very sharp opinions. Talib appears to suffer from some form of arrogance. It is quite possible, that the perspective reader may be offended.
