The whole thing has a slightly unworldly feel. However, this not a particularly accurate reflection of Aristotle's thinking. The life of the contemplator was not to be a life of physical denial. Nor was it a matter of letting the mind roam at random. Actions were to be based on sound reasoning or detailed reflection.
Education involves training people from childhood to 'like and dislike the proper things'.
But there is also something more here. Aristotle places this discipline on a pedestal. It is, for him, the highest form of human activity. Educators, if they are to follow this line, must place the gaining of knowledge for its own sake above, for example, the cultivation of affection and sympathy for other people. This is something that many of us would disagree with.
