The Psychological Basis of the Opposition to Economic Theory 1.
Every new theory encounters opposition and rejection at first.
The adherents of the old, accepted doctrine object to the new theory, refuse it recognition, and declare it to be mistaken. Years, even decades, must pass before it succeeds in supplanting the old one. A new generation must grow up before its victory is decisive. To understand this one must remember that most men are accessible to new ideas only in their youth. With the progress of age the ability to welcome them diminishes, and the knowledge acquired earlier turns into dogma.
