“Just acquiring this amount of "education" will not, by itself, make you an educated person, even less will it give you what Oakeshott calls "judgment." But if the manner of instruction is adequate, the student should be able to acquire this much knowledge in a way that combines intellectual openness, critical scrutiny, and logical clarity. If so, learning will not stop when the student leaves the university.”

“You need to know enough philosophy so that the methods of logical analysis are available to you to be used as a tool. One of the most depressing things about educated people today is that so few of them, even among professional intellectuals, are able to follow the steps of a simple logical argument.”

“There are clear cases in which "understanding" literally applies and clear cases in which it does not apply; and these two sorts of cases are all I need for this argument.”

“I cannot recall a time when American education was not in a "crisis." We have lived through Sputnik , through the era of "Johnny can't read," and through the upheavals of the Sixties. Now a good many books are telling us that the university is going to hell in several different directions at once. I believe that, at least in part, the crisis rhetoric has a structural explanation: since we do not have a national consensus on what success in higher education would consist of, no matter what happens, some sizable part of the population is going to regard the situation as a disaster. As with taxation and relations between the sexes, higher education is essentially and continuously contested territory. Given the history of that crisis rhetoric, one's natural response to the current cries of desperation might reasonably be one of boredom.”

“The sense in which an automatic door "understands instructions" from its photoelectric cell is not at all the sense in which I understand English.”
