What does "educated" mean?

What does it mean to be "educated"? It means that one shows evidence of learning. This is different than showing evidence of schooling; there all one might produce is a diploma.  A display of learning is different in that it makes manifest evidence of knowledge gained about a particular subject. Because there are so many variables here, qualifiers are often added.  He is self-educated. She is formally educated. They are college educated. These adjectives indicate where the education came from but say nothing about the quality of the learning. Hence, we sometimes describe people as well educated.  This indicates that the learning displayed is somehow deemed worthy, valuable, even impressive by those witnessing its display. This, of course, is open to personal opinion. Saying that one is well educated seems to imply a well-roundedness that can come from education about a variety of subjects, not necessarily calling for expertise in any one.
