Does this mean that the men who served the inquisition were neither fair nor open minded as men or that in their jobs what some people might call fairness or open mindedness did to operate. If the latter point is being made, it seems to me that both are merely the normal characteristics of bureaucracy as seen from the perspective of someone who is getting snarlled in the red tape. I am prepared to agree that the functionaries in a bureaucracy, e.g. the IRS, are rarely regarded as either fair or open minded by their victims and more often than not functionaries of the IRS are considered not to be reasonable in that sense by most taxpayers. I assume that no one is arguing that inquisitors or bureaucrats of any kind must have a psychological formation which makes them unreasonable, unfair, and close minded.
Most people are likely to accept the notion that cognitive dissonance is a normal fact of life.
