Crisis economics: Path dependency and intellectual courage

"The study of the history of a certain field is not, as is commonly held, a useless display of its blind alleys or a collection of the field's trials and errors (until we got it right), but history is the fullest possible scope of study of a menu that the given field can offer. Outside of our history, we have nothing more. History of thought helps us to get rid of the intellectual brainwashing of the age, to see through the intellectual fashion of the day, and to take a couple of steps back." (Tomáš Sedlácek, Economics of Good and Evil, p. 4)
