I am taking this book slowly and hope to read most of Durant's books as the years go by.

One interesting insight: Durant says the greatest invention was the common noun. He then talks about many primitive societies that did not have separate words for colors or objects like a tree. So they had to come up with a completely different word for a red ash and a white ash. They didn’t have a word for “red,�� “ash�� or even “tree��. That got me thinking about how human beings think and that organization and language are a big part of advanced thinking. Language sort of represents organizational building blocks in our minds and by using a higher level of organization, we can not only communicate much better, but can also think and plan and organize at a much higher level.
