Learning ONLY from experience

I like this recent chapter very much, as it speaks of learning from experience versus learning from school and the combination of both. It states that Russian psychologist Luria( 1979, pp 77-80) described people in the north of Russia who had only seen white bears. When they were told bears can be different colors (black, brown), they would say that unless they saw a brown bear, only white bears existed to them.
Just think about how you immediately picture a certain color when someone says a word. For example, if I said squirrel, you picture a greyish brown color. That is a typical squirrel. There are areas of the country and the world that have black squirrels, etc.
With the internet, books, schools, etc that we are used to , we are learning several different ways. The people who lived many years ago could only learn from what they (or someone else) had actually seen.
Just imagine how many folk tales were created due to one person "learning" from another. If someone said they saw a Bigfoot, then that was all you knew.
Experience is a wonderful way to learn, but it cannot be the only way one learns. In my opinion, a combination of experience and schooling is ideal, since you get your own perception of the world, as well as learned skills from others.
