Reality is a formidable opponent. It never loses. Sometimes the victory is immediate; in the political, cultural, and economic domains, it may take a while longer. In any human confrontation with the intractable facts of life, physical or historical, the outcome is never in doubt. Ignorance is a serious liability in any transaction with the real world. Denial is ultimately lethal.
The most succinct definition of reality I know of is the deceptively simple dictum of the pre-Socratic philosopher Parmenides in his fragmentary poem “On the Order of Nature”: “Whatever is is!” Human error and ensuing catastrophe consist in the unfortunate propensity for believing that “things that are not are.” The modern update of the formulation is Ludwig Wittgenstein’s “Tractatus Logico-Philosophicus,” where we read, “The world is the totality of facts” (Proposition 1.1). A lie is also in itself a fact, but it is not a part of the structure of reality – that is, in the philosopher’s words, it does not satisfy the criterion of its “unalterable form.” A lie is a “negative fact,” pointing to the “non-existence of certain states of affairs.”
Lies, like imaginary objects, are protean; they can shift, change, recompose. Reality is what is “unalterable”: 2+2=4, the Archimedes Principle, the gravitational law of inverse squares, the Coriolis Effect, Ohms Law, the force of entropy, and so on. One cannot violate or deny these facts with impunity. They simply are. The same is true of historical facts, for example: over-taxation depletes a country’s resources by impoverishing its productive classes; a falling reproductive ratio leads in time to national decline; military adventurism creates domestic turmoil, but “peace in our time” is the harbinger of war; magical ceremonies do not cure serious diseases; hyperinflation can “Weimar” a loaf of bread; public entitlements cause personal dependency; and so on. Pretending otherwise, and acting on the pretence, is a recipe for an empty larder and a house in disarray.
It is much easier, of course, to reject or dismiss facts or truths where the damage is not immediate, to conflate “things which are not” with things that “are,” if the harm is deferred to a later date. One can deny sexual dimorphism, for example, and posit 32 different genders or gender identities along with a welter of ludicrous pronouns before the result of such folly becomes evident in cultural degeneration and social collapse. One can refute the fecund marriage of a man and a woman – that is, the family, as the historically validated foundation of a robust, viable, and productive society before social and cultural disintegration inevitably set in. One can suppress the provable fact of differential climate change over the eons and replace it with fashionable and scientifically untenable theories such as man-made global warming before the inevitable economic effects reduce a nation to increasing financial hardship.
