This statement is a good way to get people to think back at what they've learned in their own lives. Just think, as a 5 year old child, you thought you knew 95% of everything you needed to get by in the world. Then you go to school and with each passing year you find out a tiny but about a lot of things! You realize that there is so much that you don't know. From a society standpoint, people with little or no education are usually very sure of what they "know". Whereas, people of higher education are often heard saying that they aren't so bright. An educated person gets an immersion into many more topics than most others, and with each new topic they realize that there is so much more that they can/will never know. The undereducated person rarely ventures into new areas so they become experts in what little they do know and this gives them a false feeling of knowing more than others. These undereducated types usually "know" that there are ghosts, Spacemen, Bigfoot, and so on. And when you hear them speaking of such things they will be heard calling educated people idiots because they don't believe the same things they themselves believe in. So the reverse of the statement serves as a "proof"..The less you learn, the more you "know". (Gunslinger)
That's the story behind my signature. What's yours?
