If you are a scientist or mathematician you are going to love this book. It will give you goosebumps of pleasure. You will likely bypass the many contradictions in this work to rationality itself. You will likely see the great leap forward of the industrial revolution and the next 100 years that followed, without remembering the millions killed in the two world wars because of its success. You will likely forget that the world threatened by climate change is caused by such wonderful advances. You will embrace the concept of life, liberty, and the pursuit of happiness made by men who owned slaves, denying such freedoms to some. You mad conclude that if we were more rational the German people would not have believed in the Nazis who persuaded that your friends and neighbors of yesterday should now be eliminated. Rationality is and has always been a moving target, driven by some out of reason and by others out of self-interest and power. Rationality should accomplish much, but often doesn't because other virtues are more appealing. It would be rational if politicians were representative of the people or if wealth was shared, but power and control are more appealing. When I look at the biggest decisions in my life, none would meet the rationality test. Each has provided learning because I haven't judged with reason, logic, or formulas. Rationality today will be seen as foolishness tomorrow and if humanity is going to take a leap forward it's not going to be because of rationalty, but because of compassion which leads to better outcomes for all.
