The Trajan Column was built in order to celebrate the victories of the Roman Armies in the conquest of Dacia, during the 2nd century AD. It shows that the Romans knew and used propaganda, although in forms that for us look primitive. In those times, just as in ours, a dying empire could be kept together for a while by lies, but not forever.
At the beginning of the 5th century AD, Augustine, bishop of Hippo, wrote his "De Mendacio" ("On Lying"). Reading it today, we may be surprised at how rigid and strict Augustine was in his conclusions. A Christian, according to him, could not lie in any circumstances whatsoever; not even to save lives or to avoid suffering for someone. The suffering of the material body, said Augustine, is nothing; what's important is one's immortal soul. Later theologians substantially softened these requirements, but there was a logic in Augustine's stance if we consider his times: the last century of the Western Roman Empire.
By the time of Augustine, the Roman Empire had become an Empire of lies. It still pretended to uphold the rule of law, to protect the people from the Barbarian invaders, to maintain the social order. But all that had become a bad joke for the citizens of an empire by then reduced to nothing more than a giant military machine dedicated to oppressing the poor in order to maintain the privilege of the few. The Empire itself had become a lie: that it existed because of the favor of the Gods who rewarded the Romans because of their moral virtues. Nobody could believe in that anymore: it was the breakdown of the very fabric of society; the loss of what the ancient called the auctoritas, the trust that citizens had toward their leaders and the institutions of their state.
Auguistine was reacting to all this. He was trying to rebuild the "auctoritas", not in the form of mere authoritarianism of an oppressive government, but in the form of trust. So, he was appealing to the highest authority of all, God himself. He was also building his argument on the prestige that the Christians had gained at a very high price with their martyrs. And not just that. In his texts, and in particular in his "Confessions" Augustine was opening himself completely to his readers; telling them all of his thoughts and his sins in minute details. It was, again, a way to rebuild trust by showing that one had no hidden motives. And he had to be strict in his conclusions. He couldn't leave any openings that would permit the Empire of Lies to return.
Augustine and other early Christian fathers were engaged, first of all, in an epistemological revolution. Paulus of Tarsus had already understood this point when he had written: "now we see as in a mirror, darkly, then we'll see face to face." It was the problem of truth; how to see it? How to determine it? In the traditional view, truth was reported by a witness who could be trusted. The Christian epistemology started from that, to build up the concept of truth as the result divine revelation. The Christians were calling God himself as witness. It was a spiritual and philosophical vision, but also a very down-to-earth one. Today, we would say that the Christians of late Roman times were engaged in "relocalization", abandoning the expensive and undefendable structures of the old Empire to rebuild a society based on local resources and local governance. The age that followed, the Middle Ages, can be seen as a time of decline but it was, rather, a necessary adaptation to the changed economic conditions. Eventually, all societies must come to terms with Truth. The Western Roman Empire could not do that, It had to disappear, it was unavoidable.
Now, let's move forward to our times and we have reached our empire of lies. On the current situation, I don't think I have to tell you anything that you don't already know. During the past few decades, the mountain of lies tossed at us by governments has been perfectly matched by the disastrous loss of trust in our leaders on the part of the citizens. When the Soviets launched their first orbiting satellite, the Sputnik, in 1957, nobody doubted that it was for real and the reaction in the West was to launch their own satellites. Today, plenty of people even deny that the US sent men to the moon in the 1960s. They may be ridiculed, they may be branded as conspiracy theorists, sure, but they are there. Perhaps the watershed of this collapse of trust was with the story of the "Weapons of Mass Destruction" that we were told were hidden in Iraq. It was not their first, nor it will be their last, lie. But how can you ever trust an institution that lied to you so brazenly? (and that continue to do so?)
Today, every statement from a government, or from an even remotely "official" source, seems to generate a parallel and opposite statement of denial. Unfortunately, the opposite of a lie is not necessarily the truth, and that has originated baroque castles of lies, counter-lies, and counter-counter lies. Think of the story of the 9/11 attacks in New York. Somewhere, hidden below the mass of legends and myths that have piled up on this story, there has to be the truth; some kind of truth. But how to find it when you can't trust anything you read on the Web? Or think of peak oil. At the simplest level of conspiratorial interpretation, peak oil can be seen as a reaction to the lies of oil companies that hide the depletion of their resources. But you may also see peak oil as a scam created by oil companies that try to hide the fact that their resources are actually abundant - even infinite in the diffuse legend of "abiotic oil". But, for others, the idea that peak oil is a scam created in order to hide abundance may be a higher order scam created in order to hide scarcity. Eve higher order conspiracy theories are possible. It is a fractal universe of lies, where you have no reference point to tell you where you are.
Eventually, it is a problem of epistemology. The same that goes back to Pontius Pilate's statement "what is truth?" Where are we supposed to find truth in our world? Perhaps in science? But science is rapidly becoming a marginal sect of people who mumble of catastrophes to come. People whom nobody believes any longer after they failed to deliver their promises of energy too cheap to meter, space travel, and flying cars. Then, we tend to seek it in such things as "democracy" and to believe that a voting majority somehow defines "truth". But democracy has become a ghost of itself: how can citizens make an informed choice after that we discovered the concept that we call "perception management" (earlier on called "propaganda")?
Going along a trajectory parallel to that of the ancient Romans, we haven't yet arrived at having a semi-divine emperor residing in Washington D.C., considered by law to be the repository of divine truth. And we aren't seeing yet a new religion taking over and expelling the old ones. At present, the reaction against the official lies takes mostly the form of what we call "conspiratorial attitude." Although widely despised, conspirationism is not necessarily wrong; conspiracies do exist and much of the misinformation that spreads over the web must be created by someone who is conspiring against us. The problem is that conspirationism is not a form of epistemology. Once you have decided that everything you read is part of the great conspiracy, then you have locked yourself in an epistemological box and thrown away the key. And, like Pilate, you can only ask "what is truth?", but you will never find it.
Is it possible to think of an "epistemology 2.0" that would allow us to regain trust on the institutions and on our fellow human beings? Possibly, yes but, right now, we are seeing as in a mirror, darkly. Something is surely stirring, out there; but it has not yet taken a recognizable shape. Maybe it will be a new ideal, maybe a revisitation of an old religion, maybe a new religion, maybe a new way of seeing the world. We cannot say which form the new truth will take, but we can say that nothing new can be born without the death of something. And that all births are painful but necessary.
