How Mumbo-Jumbo Conquered the World: A Short History of Modern Delusions: Summary & Key Insights

The Enlightenment was the great leap forward—humankind’s declaration that reason would liberate it from myth and divine whim. Voltaire, Kant, Hume, and many others fought for the idea that evidence, debate, and universal human rights could replace dark superstition. The tragedy, as I see it, is that this legacy has been betrayed. In the closing decades of the twentieth century, the intellectual atmosphere began to thicken with fog once more. Astrology reappeared as lifestyle advice in respectable papers; corporate leaders quoted mystics rather than scientists; even politicians used ‘spiritual energy’ as a policy metaphor. It was as if history had spun backward.

I wanted readers to understand that this betrayal didn’t happen overnight. It crept in gradually, as skepticism was portrayed as cynicism and belief began to seem more virtuous than expertise. The Enlightenment valued the contest of ideas, but today’s culture prizes comfort and affirmation. Rational debate became suspect for its ‘coldness’, as though demanding proof were an act of cruelty. The irony is that the Enlightenment’s tools still exist—education, free inquiry, public discourse—but we wield them timidly. We have allowed 'belief' to occupy spaces once reserved for reason.

To betray reason is to betray democracy itself. When public opinion begins to prefer sentimental reassurance over factual precision, the citizen becomes a consumer, and the politician becomes a performer. My lament in this chapter isn’t nostalgic—it’s a warning that the rational foundations of modern civilization endanger themselves when treated as optional.

Postmodernism arrived disguised as intellectual liberation. It spoke the language of freedom—no grand narratives, no absolute truths, no oppressors in white lab coats insisting that facts exist independently of perspective. Yet, beneath this progressive posture lay a toxin. By denying objective reality, postmodernism unintentionally undermined the very principle that allowed it to flourish: rational critique. The paradox was cruel. The tools forged by Enlightenment reason were being used to dismantle the concept of reason itself.

I watched as this philosophy spilled from art departments into political and social thinking. Suddenly every opinion became equal, every version of truth a cultural artifact rather than a testable statement. Scientific debates were recast as struggles between 'discourses'. Facts were no longer settled by evidence but by the rhetorical power of the speaker. The outcome, unsurprisingly, was chaos—a cacophony where pseudoscience and prophecy claimed academic legitimacy.

When everything is relative, even absurdity finds refuge. Conspiracy theories, faith healing, and magical economic thinking gained immunity because to criticize them was to assert an 'oppressive' rational framework. My argument in this chapter is not merely against postmodernism as a philosophy but against its cultural consequences. Relativism didn’t democratize truth—it privatized it, fragmenting common sense into infinite solipsism. Once we abandon shared standards of verification, civilization becomes a theatre of competing fantasies.
