Great quote, George. I have one from earlier than that:
Perhaps we are not fully aware of the extent to which instruction and education are accepted as being essentially the same thing. I think you would find, if you looked into it, for instance, that all the formal qualifications for a teacher’s position rest on this understanding. A candidate is certificated — is he not? — merely as having been exposed satisfactorily to a certain kind of instruction for a certain length of time, and therefore he is assumed eligible to a position which we all agree that only an educated person should fill. Yet he may not be at all an educated person, but only an instructed person. We have seen many such, and five minutes’ talk with one of them is quite enough to show that the understanding of instruction as synonymous with education is erroneous. They are by no means the same thing. Let us go no further at present in trying to determine what education is, but merely take note that it is not the same thing as instruction.
