The other day, my friend Trevor, a PhD-student at La Trobe, sent me these excellent quotes:
The monomaths do not only swarm over a specialism, they also play dirty. In each new area that Posner picks—policy or science—the experts start to erect barricades. “Even in relatively soft fields, specialists tend to develop a specialised vocabulary which creates barriers to entry,” Posner says with his economic hat pulled down over his head. “Specialists want to fend off the generalists. They may also want to convince themselves that what they are doing is really very difficult and challenging. One of the ways they do that is to develop what they regard a rigorous methodology—often mathematical.
“The specialist will always be able to nail the generalists by pointing out that they don’t use the vocabulary quite right and they make mistakes that an insider would never make. It’s a defence mechanism. They don’t like people invading their turf, especially outsiders criticising insiders. So if I make mistakes about this economic situation, it doesn’t really bother me tremendously. It’s not my field. I can make mistakes. On the other hand for me to be criticising someone whose whole career is committed to a particular outlook and method and so on, that is very painful.”
