I believe education can be encompassed in the cheesy phrase of "there is a difference between listening and hearing." Education is when one listens with the intent to gain knowledge to better themself, simply know more about something, or they just find something interesting. I believe that to be educated is to hold onto a continuous gain of knowledge. To stop listening or taking in knowledge is to stop being educated. Say for instance we gained knowledge but stopped learning in the third grade, we would not 10 years later be considered educated. One has to have a drive to continuously and voluntarily learn and gain this knowledge.
The difference I see is take a mechanic for instance. Someone showing him how to work his first computer who has been doing it for years may SEE him as uneducated. But, if you were to reverse the tables I bet he could show the computer guy everything about cars. However, if the mechanic stopped learning and educating himself about new cars and new things eventually he will be seen as uneducated by those even wanting to know about cars, and even by the computer guy. This can be seen vice versa between the two as well.
So, in cliffs, to be educated is to continuously strive to gain knowledge and make a voluntary act to gain this knowledge. It cannot be forced into you, because listening is not the same as hearing. It is a voluntary action.
My thoughts.
