The cause of all the problems in modern education can be summarized in three words: Darwin, Marx and Freud

Darwin. Marx. Freud. 
That's right.

The theories of these three men have pervaded all modern thought. Their ideas are much alike in that they are narrow, materialistic, fatalistic, and utterly anti-Christian.

Their influence has been felt far beyond their limited fields.

• Darwin's ideas have contributed to a blind belief in progress. They have also served for justification for cut-throat capitalism and the survival of the fittest mentality in our commercial and political relations.
• Marx's ideas plunged half the world into darkness for most of the last century, but in the other half of the world, they have served as the justification for the extended growth of the State and the loss of the authority of the family and the centrality of the home.
• And Freud's ideas have led to an overemphasis on sex and have served as the justification for the normalization of the abnormal, and the pervasive decline in morality. 

The academic's utter sellout to these three figures has elevated science, economics and psychology above religion. In fact, all of these three have been invoked to explain away religion.

Chesterton says that the primary public duty today is 

"... not to educate the uneducated but to uneducate the educated." 

We can start this process, the process of bring common sense back to education, by tossing out Darwin, Marx and Freud, and all their minions, or studying them solely for the purpose of finding out what the enemy is up to. 

Chesterton does not say there is absolutely no truth in Darwin, Marx and Freud; he says that the minor truths that they got hold of, they stated entirely out of proportion to a thousand other truths.
