Some claim that we are living in a post-true era. In support of this claim, people often use the example of the linked success of Trump and fake news. This does make a good case that untruth has triumphed over truth. But, then again, the truth seems to remain.
Imagine people tenting in the jungle of the real. Within the tent, people create narratives and are rewarded or punished based on whether others believe their tales. Or at least find them useful. Some people realized that it did not matter whether their tales were true and found that lies were often consumed like candy. They became convinced that all that mattered was their stories and the success they brought. But they were wrong.
Outside the tent, stalking the jungle of the real, is a tiger. The tiger does not care about the narratives. The thin fabric is no protection from its claws. The tiger might pass by the tent while doing nothing. But someday, perhaps soon, the tiger will tear through fabric and its hunger will not be satisfied by even the sweetest of lies.
While a metaphor is not an argument, the tale of the tiger can be made into one. The tent is the society we construct that serves the thin wall between us and the rest of world (the jungle of the real). The people in the tent are us and the untrue narratives are the lies. The tiger is truth, which is how things really are. As in the metaphor, no matter what lies people tell, the truth remains true. While people can profit from lies and avoid the consequences, reality remains unchanged. For example, consider the narrative woven by the sugar industry about sugar, fats and heart disease. This tale, told within the tent, has shaped the American diet for decades and has served the sugar industry well. But reality is not changed by these narratives and the consequences are serious. Tobacco companies provide another example and perhaps the best example is climate change. Some claim that climate change is a lie told by a global conspiracy of scientists. Others think that its denial is a lie spread at the behest of those who profit from fossil fuels. One side is weaving a false narrative, but the tiger is out there.
It might be claimed that this is not really a post-truth era in the sense of there being no truth. Rather, the post truth era is defined by the fact that truth matters little, if at all, in some contexts. In one sense, this is true. Trump was, for example, has been rewarded for his relentless untruths and has a good chance of being elected in 2024. Some who peddle fake news and other false content have enjoyed great financial success, thus showing there can be profit in lies. On this view, Ben Franklin is wrong: honesty is no longer the best policy, lying is. At least in the context of politics and business.
In another sense, this is not true. While lying has proven an effective short-term strategy, it will ultimately run up against the truth. Going back to the metaphor, the tiger is always out there. As an example, while the false narrative denying climate change has resulted in short term success, it will prove to be a long-term disaster. Those who believe it is real claim that the danger is climate change. Those who deny climate change claim disaster will result from the catastrophic environmental policies imposed by “the liberals.” Both agree reality will impose a disaster but disagree on its nature. While both cannot be right, they are both right that ignoring the truth will be a disaster.
It could be countered that I am wrong because I am considering the impact of such lies broadly. That is, I am focused on how their consequences can impact people in general. I should, one might argue, focus on the advantages to those engaged in the untruths. In philosophical terms, this is the claim that one should embrace ethical egoism, which is the moral theory that what is right is to maximize value for oneself. Alternatively, one could just accept selfishness as a virtue.
While an unskilled liar can end up in trouble, those with a talent for untruth can benefit from their lies while the harmful consequences impact others. One way this can happen is that the harm can lie in the future. For example, lies about the climate will not harm the liars in the elite classes today for they will be dead before the greatest consequences would impact them. This can also happen when the harms occur to other people and liar avoids them through being far from the harms. For example, lies about the safety of a town’s water would not impact the health of a governor who does not live in that town.
A third way is that the liar might be able to protect themselves through their wealth or position. For example, a rich straight white Christian who lies about things impacting Muslims, blacks, gays or poor people does not reap the harms of those lies. These consequences fall upon the targets of their lies.
A selfish reply to this is that most of us are more likely to be harmed by broad lies than benefited by them. This is because most of us care about our relatives who will be alive when we are gone, because most of us live in the impact zone of lies, and because most of us lack the status and wealth to escape the consequences of broad lies. As such, we have a selfish interest in opposing lying as it will hurt us and those we care about.
An altruistic reply is that we should care about other people and the harm they suffer. This can also be argued for on utilitarian moral grounds—that this lying will create more unhappiness than happiness for everyone. There is also the religious argument. Many religions purport to endorse the truth and enjoin us to show compassion for others, to love each other as God has loved us. As such, the post-truth world should be rejected. Honesty is, as Ben said, the best policy.
