Schools of Economic Thought

How many different schools of thought exist in Economics?

Over thirty, and well, given the admirable innovativeness of researchers, we are still counting.

The following list attempts to mention most schools that we assume are relevant (we are leaving out very very old and obscure ones):

1. Classical Political Economy
2. American
3. French Liberal
4. German Historical
5. French Historical
6. Utopian
7. Marxian
8. State Socialism
9. Ricardian
10. Anarchist
11. Institutional and New Institutional
12. Neo Classical (called Orthodox these days)
13. Austrian
14. Stockholm
15. Keynesian
16. Chicago
17. Carnegie
18. Regulation
19. Neo Ricardian
20. Post Keynesian
21. New Keynesian
22. New Classical Macroeconomics
23. Evolutionary
24. Non-equilibrium

Which one do you find the most reasonable and least absurd?
