Defining clear terms is a problem here as there is so much gray as we try to distinguish the difference between knowledge and education. An example: a couple of years ago I watched a webinar lecture from Harvard's free online course lectures series about "Historical Preservation in Havana, Cuba." Many universities now offer this type of service. For me this was self-directed knowledge. I gained some useful knowledge that I could apply in a practical way had I chosen. Could this same knowledge also be considered education. Harvard would not likely acknowledge my watching their free lecture as education unless I paid them tuition. If I paid Harvard tuition, would the same lecture immediately transform from knowledge into education?
Some say education is a process or systematic distribution of knowledge. In this case I could claim that I did receive an education and that I can now apply this knowledge.
