“The ideas of economists and political philosophers, both when they are right and when they are wrong, are more powerful than is commonly understood. Indeed, the world is ruled by little else. Practical men, who believe themselves to be quite exempt from any intellectual influences, are usually the slaves of some defunct economist. […] I am sure that the power of vested interests is vastly exaggerated compared with the gradual encroachment of ideas.”
This is how Keynes concluded his General Theory. I wonder whether this is still true (if ever it was) in the post-modern era when tecnology rather than culture seems to be the dominating force. But if it was at least in part still the case, than we must develop a system of political ideas that are capable of enslaving "practical men" to serve the building of a new society of justice, truth and absence of plunder.
I do not think this set of ideas can be scientific. Rather they should form an ideology and a practical strategy. Because an ideology disconnected from a long term strategy is like theory without practice or practice without theory: "theoria sine praxis rota sine axis. Praxis sine theoria coecum in via".
