There is no such thing as education. The thing is merely a loose phrase for the passing on to others of whatever truth or virtue we happen to have ourselves. It is typical of our time that the more doubtful we are about the value of philosophy, the more certain we are about the value of education. That is to say, the more doubtful we are about whether we have any truth, the more certain we are (apparently) that we can teach it to our children.
