Similar to the use of Marxism for "explaining" how societies must change, Freudianism became dominant in the 20th century. For a few decades it was, anyway.

Freudianism was used to attack all established societies. Its proponents defined anything they didn't like as “repressed”. In the middle of the 1900s, academic writing was filled with Freudian references and concepts.

But when medical science provide psycho-therapeutic treatments, Freudiannism faded away.

And yet, it's the widespread willful belief of "scientific societies" that's interesting. Why do educated people eagerly accept such claims?

This blog will return to this theme again. Why thy pseudo-religious acceptance of socialism?
