The Kingdom of Nouns

A fine read on the dangers of program design relying too much on a single metaphor, like Object-Oriented Programming and Java

The residents of the Kingdom of Java aren't merely happy — they're bursting with pride!

StateManager.getConsiderationSetter("Noun Oriented Thinking", State.HARMFUL).run()

Or, as it is said outside the Kingdom of Java, "Noun Oriented Thinking Considered Harmful".

Object Oriented Programming puts the Nouns first and foremost. Why would you go to such lengths to put one part of speech on a pedestal? Why should one kind of concept take precedence over another? It's not as if OOP has suddenly made verbs less important in the way we actually think. It's a strangely skewed perspective. As my friend Jacob Gabrielson once put it, advocating Object-Oriented Programming is like advocating Pants-Oriented Clothing.

Java's static type system, like any other, has its share of problems. But the extreme emphasis on noun-oriented thought processes (and consequently, modeling processes) is more than a bit disturbing. Any type system will require you to re-shape your thoughts somewhat to fit the system, but eliminating standalone verbs seems a step beyond all rationale or reason.
