“People always learn what they have to, what is appropriate to their environment. Han, you grew up in a culture which has schools for general purpose and schools for every conceivable subclassification of data, but they do not as a rule spread knowledge or wisdom—just assemblies of data. As you have them, schools work on your society just like the differentiating fashions in clothes your sexes use, and hair styles as well—they obscure the innate differences, muddy them, make everyone equal, but it is the equality of a façade. People really are different from one another. And schools obscure the only kinds of knowledge worth knowing.”

–The character Liszendir Srith-Karen in M.A. Foster’s The Warriors of Dawn (1975)
