Given the high degree of specialization in a modern economy, demanding that everything "justify itself before the bar of reason" means demanding that people who know what they are doing must be subject to the veto of people who don't have a clue about the decisions that they are second-guessing.
It means demanding that ignorance override knowledge.
The ignorant are not just some separate group of people. As Will Rogers said, everybody is ignorant, but just about different things.

Every time oil prices shoot up, there are cries of "greed" and demands by politicians for an investigation of collusion by Big Oil. There have been more than a dozen investigations of oil companies over the years, and none of them has turned up the collusion that is supposed to be responsible for high gas prices.
Now that oil prices have dropped big time, does that mean that oil companies have lost their "greed"? Or could it all be supply and demand -- a cause and effect explanation that seems to be harder for some people to understand than emotions like "greed"?
