Whether in English or in French, I don’t believe Foucault ever uttered the words, ‘It is meaningless to speak in the name of – or against – Reason, Truth, or Knowledge‘*, but I don’t think he’d disagree with the sentiment.
Foucault was a postmodernist, and on balance, political Conservatives (Rightists?) dislike the notion of postmodernism. Evidently, a lot of Postmodernists are also Leftists (Progressives or Liberals in the US), so somehow critics such as Jordan Peterson conflate the two clearly distinct concepts.
A basis for Conservatism is the notion of an objective truth, and despite recent sociopolitical trends, they at least say they are guardians or truth and purveyors of knowledge. Conservatives (OK, so I am broad-brushing here) are staunch individualists who believe strongly in possession and property, of material, of an objective reality. Fundamentally, the are aligned to a monotheistic god or at least some discernible (and objective) moral compass.
On the Left, especially post-Enlightenment, they’ve substituted God with some anthropomorphic Nature. In fact, they find comfort in natural laws and human nature. Science is often their respite because science is objective. Isn’t it? Leftists are friends or Reason, and one can’t acquire enough knowledge. Moderation need not apply here; the more the merrier.
This being said, evidently, many on the Left seem to have abandoned this comfort zone. Of course, this may be because the Left-Right dichotomy doesn’t capture the inherent nuance, and so they were miscategorised—perhaps, much in the same manner as persons are miscategorised in a binary gender system. No. It must be something else.
In any case, both side claim to the parties of knowledge, reason, and truth because the opposing parties are clearly abject morons. There is no hint of irony in the situation where each side claims some objective notion of truth—whether divinely granted or self-evidently reasoned—, yet they can’t resolve what the true truth is. If only the other side were more rational.
By now, we are well aware of the demise of homo economicus, the hyper-rational actor foundational to modern economic theory. In reality, humans are only rational given the loosest definitions, say, to (in most cases) know enough to get in the shade on a 37.2°C day. However, as behavioural economist Dan Ariely noted by the title of his book, people are Predictably Irrational. Ariely is just standing on the shoulders of Kahneman and Tversky and Richard Thaler. My point is that humans are only marginally rational.
As I’ve written elsewhere, truth is nothing more than a rhetorical endpoint. It is hardly objective. It’s a matter of opinion. Unfortunately, systems of government and jurisprudence require this objective truth. In truth—see what I did there?—, social fabric requires a shared notion of truth.
A shared notion doesn’t imply that this notion is objective, but if it’s not objective, how does one resolve differences of opinion as to which is the better truth. Without establishing a frame and a lens, this is impossible. The problem is that frames and lenses are also relative. Whether the members accept a given frame or lens is also a matter of rhetoric. It’s turtles all the way down.
Even if all members agree on all parameters of truth at day 0, there is nothing to prevent opinion changes or from new members not to share these parameters. Such is always the problem with social contract theory. [How does one commit to a contract s/he is born into with little recourse to rescind the contract, renegotiate terms, or choose a different contract option. The world is already carved up, and the best one can do is to jump from the frying pan into the fire.]
In the end, the notion of truth is necessary, but it doesn’t exist. Playing Devil’s advocate, let’s say that there is a single purveyor of Truth; let’s just say that it’s the monotheistic Abrahamic God of Judeo-Christian beliefs. There is no (known) way to ascertain that a human would have the privilege to know such a truth nor, if s/he were to encounter, say, a burning bush of some sort, that this entity would be conveying truth; so, we aren’t really in a better place. Of course, we could exercise faith and just believe, but this is a subjective action. We could also take Descarte’s line of logic and declare that a good God would not deceive us—sidestepping that this ethereal being was good, as advertised. I’m afraid it’s all dead ends here, too.
And so, we are back to where we started: no objective truth, limited ability to reason, and some fleeting notion of knowledge. We are still left with nothing.
Enter the likes of Jordan Peterson, he with his fanciful notion of metaphysics and morality—a channeller of Carl Jung. His tactic is to loud dog the listener and outshout them indignantly. His followers, already primed with a shared worldview, are adept (or inept) cheerleaders ready to uncritically echo his refrain. To them, his virtue-ethical base, steeped in consequentialism awash in deontology, Peterson speaks the truth.
He also potentiates the selfish anti-collective germ and rage of the declining white man. He’s sort of a less entertaining Howard Stern for the cleverer by half crowd. He gives a voice to the voiceless—or perhaps the thoughtless. He uses ‘reason’ to back his emotional pleas. He finds a voice in the wilderness where white Western males are the oppressed. If only they hadn’t been born centuries earlier—albeit with iPhones and microwaves.
Those would be the days.
