The world changed when the Berlin Wall fell in 1989. From a practical perspective, the physical barrier separating communism from capitalism had been removed. But the worldview shift it signified had far greater ramifications for all of us. That momentous event in Germany sounded the death knell for modernism.
Modernism is the worldview that spawned almost every evil ideology that dominated the twentieth century: Darwinism, Marxism, fascism, atheism, theological liberalism, you name it. Science was enshrined, the miraculous denied, and human reason deified. It was the age of rationalism.
But the trail of disasters and dead bodies was impossible to ignore. Postmodernism then usurped the modernistic worldview by rightly acknowledging its immense failures. While postmodernists dispensed with the rationalism of their predecessors, they foolishly did away with rational thought as well.
Getting Propositions Off the Premises
What typifies postmodernism is a general suspicion of rational and logical forms. Postmodernists don’t like to discuss truth in plain propositional terms.
Postmodernism is primarily a reaction against the unbridled rationalism of modernity. But many postmodernist’s response to rationalism is a serious overreaction. Plenty of postmodernists seem to entertain the notion that irrationality is superior to rationalism.
Actually, both ways of thinking are dead wrong and equally hostile to authentic truth and biblical Christianity. One extreme is as deadly as the other. Rationalism needs to be rejected without abandoning rationality.
Rationality (the right use of sanctified reason through sound logic) is never condemned in Scripture. Faith is not irrational. Authentic biblical truth demands that we employ logic and clear, sensible thinking. Truth can always be analyzed and examined and compared under the bright light of other truth, and it does not melt into absurdity. Truth by definition is never self-contradictory or nonsensical. And contrary to popular thinking, it is not rationalism to insist that coherence is a necessary quality of all truth. Christ is truth incarnate, and He cannot deny himself (2 Timothy 2:13). Self-denying truth is an absolute contradiction in terms. “No lie is of the truth” (1 John 2:21).
Nor is logic a uniquely “Greek” category that is somehow hostile to the Hebrew context of Scripture. (That is a common myth that is often set forth in support of postmodernism’s flirtation with irrationality.) Scripture frequently employs logical devices, such as antithesis, if-then arguments, syllogisms, and propositions. These are all standard logical forms, and Scripture is full of them—Paul’s long string of deductive arguments in 1 Corinthians 15:12–19 being a great example.
Yet we often encounter people enthralled with postmodern ideas who argue vehemently that truth cannot be expressed in bare propositions like mathematical formulae. Even some professing Christians nowadays argue along these lines: If truth is personal, it cannot be propositional. If truth is embodied in the person of Christ, then the form of a proposition can’t possibly express authentic truth. That is why most of Scripture is told to us in narrative form—as a story—not as a set of propositions.
The reason behind postmodernism’s contempt for propositional truth is not difficult to understand. A proposition is an idea framed as a logical statement that affirms or denies something, and it is expressed in such a way that it must be either true or false. There is no third option between true and false. (This is the “excluded middle” in logic.) The whole point of a proposition is to boil a truth-statement down to such pristine clarity that it must be either affirmed or denied. In other words, propositions are the simplest expressions of truth value used to express the substance of what we believe. Postmodernism, frankly, cannot endure that kind of stark clarity.
In reality, however, postmodernism’s rejection of the propositional form turns out to be totally untenable. It is impossible to discuss truth at all—or even tell a story—without resorting to the use of propositions. Until fairly recently, the validity and necessity of expressing truth in propositional form was considered self-evident by virtually everyone who ever studied logic, semantics, philosophy, or theology. Ironically, to make any cogent argument against the use of propositions, a person would have to employ propositional statements! So every argument against propositions is instantly self-defeating.
Let’s be clear: truth certainly does entail more than bare propositions. There is without question a personal element to the truth. Jesus Himself made that point when He declared Himself truth incarnate. Scripture also teaches that faith means receiving Christ for all that He is—knowing Him in a real and personal sense and being indwelt by Him—not merely assenting to a short list of disembodied truths about Him (Matthew 7:21–23).
So it is quite true that faith cannot be reduced to mere assent to a finite set of propositions (James 2:19). I have made that point repeatedly in several books. Saving faith is more than a merely intellectual nod of approval to the bare facts of a minimalist gospel outline. Authentic faith in Christ involves love for His person and willingness to surrender to His authority. The human heart, will, and intellect all consent in the act of faith. In that sense, it is certainly correct, even necessary, to acknowledge that mere propositions can’t do full justice to all the dimensions of truth.
On the other hand, truth simply cannot survive if stripped of propositional content. While it is quite true that believing the truth entails more than the assent of the human intellect to certain propositions, it is equally true that authentic faith never involves anything less. To reject the propositional content of the gospel is to forfeit saving faith, period.
Postmodernists are uncomfortable with propositions for an obvious reason: They don’t like the clarity and inflexibility required to deal with truth in propositional form. A proposition is the simplest form of any truth claim, and postmodernism’s fundamental starting point is its contempt for all truth claims. The “fuzzy logic” of ideas told in “story” form sounds so much more elastic—even though it really is not. Propositions are necessary building blocks for every means of conveying truth—including stories.
But the attack on propositional expressions of truth is the natural and necessary outworking of postmodernism’s general distrust of logic, distaste for certainty, and dislike for clarity. To maintain the ambiguity and pliability of “truth” necessary for the postmodern perspective, clear and definitive propositions must be discounted as a means of expressing truth. Propositions force us to face facts and either affirm or deny them, and that kind of clarity simply does not play well in a postmodern culture.
As you may be aware, the General Data Protection Regulation (GDPR) comes into full effect on 25th May 2018. GDPR is the new European privacy regulation, which will replace the Data Protection Act 1998 in the UK and the equivalent legislation across the EU Member States.
Here at Grace to You Europe we take our data protection responsibilities very seriously and, as you would expect, have undertaken a significant programme of work to ensure that we are ready for this important legislative change.
