The original article was about bias in political science university courses, but I think the following quote sums up quite accurately what the aim of a third-level education really is:

The question is, whether students come out of the class having learned to reason about a set of problems or not. The content is not as important, since they’ll forget a lot of the content anyway, and will receive it selectively, both during and after the class. But if you teach them to take things apart and see how they work, to think about social and political causation, to see how things work together, in a particular field, then they can produce their own knowledge and understanding about it thereafter.
