The Thinker and His Unfinished Masterwork
Blaise Pascal (1623-1662) was one of the most extraordinary intellects of the seventeenth century - a mathematician who invented the mechanical calculator and founded probability theory, a physicist who demonstrated atmospheric pressure and the vacuum, and a prose stylist whose Provincial Letters (1656-1657) are among the masterpieces of French literature. The Pensees (Thoughts), published posthumously in 1670, eight years after Pascal's death at age thirty-nine, are the fragmentary notes for an Apology for the Christian Religion that he never completed. Despite their unfinished state - approximately 1,000 fragments ranging from single sentences to extended arguments - the Pensees constitute one of the most psychologically penetrating and philosophically rigorous defenses of Christian faith ever written.
Pascal's intellectual crisis came in 1654 when he experienced a mystical encounter with God on the night of November 23 - the 'Night of Fire' - which he recorded on a slip of paper (the 'Memorial') that was found sewn into his coat after his death: 'Fire. God of Abraham, God of Isaac, God of Jacob, not of the philosophers and of the learned.' This experience radicalized his conviction that the God of the Bible is not the abstract deity of philosophical theism but the living God who addresses human beings in their concrete, existential situation.
Biblical Texts Engaged
Romans 5:12 - 'Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned' (KJV) - provides the anthropological foundation of the Pensees. Paul's doctrine of original sin, as developed by Augustine, is Pascal's key to understanding the human condition. Humanity is simultaneously great (created in God's image, capable of thought and love) and miserable (fallen, self-deceiving, mortal). Only the doctrine of the Fall explains this paradox: we are not as God made us, but we retain traces of our original grandeur.
Genesis 3:19 - 'In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou art, and unto dust shalt thou return' - supplies the existential framework: human life is bounded by death, and all human activity (what Pascal calls 'diversion') is an attempt to avoid confronting this reality.
Jeremiah 17:9 - 'The heart is deceitful above all things, and desperately wicked: who can know it?' - informs Pascal's analysis of self-deception. The human heart does not simply fail to know the truth; it actively conceals the truth from itself. This is why rational arguments alone cannot bring a person to faith: the obstacle is not intellectual but volitional.
Pascal also engages Isaiah 45:15 - 'Verily thou art a God that hidest thyself, O God of Israel, the Saviour' - which he takes as the key to his apologetic strategy. God is a Deus absconditus, a hidden God, who provides enough evidence for faith but not enough for certainty, so that faith remains a genuine choice requiring the engagement of the will.
Core Argument
The Pensees follow an apologetic strategy that is psychological rather than metaphysical. Pascal does not begin with proofs of God's existence (he regards the cosmological and ontological arguments as intellectually valid but existentially ineffective) but with an anatomy of the human condition designed to make the reader feel the need for God.
The argument proceeds in stages. First, Pascal establishes the misery of man without God. Human beings are caught between two infinities - the infinitely large (the universe) and the infinitely small (the atom) - and are unable to comprehend either. We are 'thinking reeds' (roseaux pensants): the most fragile things in nature, yet greater than the universe because we know that it crushes us and it does not know. We spend our lives in 'diversion' (divertissement) - hunting, gambling, socializing, working - to avoid confronting our mortality and our emptiness.
Second, Pascal argues that this condition is explicable only by the Christian doctrine of the Fall. Philosophy cannot account for the simultaneous greatness and wretchedness of humanity. The Stoics saw only human greatness and counseled pride; the skeptics saw only human wretchedness and counseled despair. Only Christianity 'teaches men these two truths alike: that there is a God whom men can know, and that there is a corruption in their nature which renders them unworthy of Him' (Fragment 555, Lafuma edition).
Third, Pascal presents the famous 'Wager' (le Pari, Fragment 233). Faced with the impossibility of proving God's existence by reason alone, Pascal argues that the decision to believe or not believe is inescapable - 'you must wager; it is not optional' - and that the rational calculation favors belief: if God exists, the believer gains infinite happiness; if God does not exist, the believer loses nothing of consequence. The Wager is not presented as a proof of God's existence but as a pragmatic argument for beginning the journey of faith - for acting as if one believed, in the expectation that genuine belief will follow.
Fourth, Pascal examines the evidence for Christianity: the fulfillment of prophecy, the miracles, the moral transformation of the apostles, the persistence of the Church. He argues that Christianity fits the human condition better than any alternative - that it alone diagnoses the disease (sin) and provides the cure (grace).
Intellectual Context
Pascal was responding to several intellectual currents. Against Descartes's rationalism - which sought to ground all knowledge in the certainty of the thinking subject - Pascal argued that 'the heart has its reasons, which reason does not know' (Fragment 277). This is not anti-intellectualism but a recognition that existential truths (the reality of other minds, the goodness of first principles, the existence of God) are apprehended by a faculty deeper than discursive reason.
Against the libertine skeptics of seventeenth-century Paris - particularly his friend the Chevalier de Mere and the tradition descending from Montaigne - Pascal argued that skepticism is self-refuting: the skeptic who doubts everything cannot even doubt consistently. But Pascal also appropriated skeptical insights, using them to demolish human pretensions to self-sufficiency and to create the existential vacuum that only God can fill.
Against the Jesuits (in the Provincial Letters), Pascal argued that casuistic moral theology had corrupted Christianity by accommodating it to worldly standards. The Pensees continue this critique implicitly: Christianity is not a comfortable moral system but a radical encounter with a God who demands everything.
Reception and Critique
The Pensees have been received very differently across traditions. Catholic reception has been complicated by Pascal's Jansenism - his association with the Port-Royal movement, which emphasized Augustinian doctrines of grace and predestination that the Jesuits considered quasi-Protestant. Pope Alexander VII condemned five propositions attributed to Jansenius in 1656, and Pascal's Provincial Letters were placed on the Index of Forbidden Books in 1657. Nevertheless, the Pensees have been widely admired by Catholic thinkers; Romano Guardini called them 'the most important apologetic work of modern times.'
Protestant reception has been more straightforwardly positive. Kierkegaard acknowledged Pascal as a predecessor in the existential approach to faith. Karl Barth, despite his general suspicion of apologetics, respected Pascal's insistence on the qualitative difference between God and humanity. T.S. Eliot, an Anglo-Catholic, wrote an influential introduction to the Pensees (1931) praising Pascal's psychological acuity and arguing that the Wager, properly understood, is not a cynical gambit but a recognition that faith begins with a practical commitment.
Secular critics have engaged the Wager extensively. Voltaire dismissed it as mercenary. William James, in 'The Will to Believe' (1896), offered a more sympathetic treatment, arguing that in cases where evidence is insufficient, the will plays a legitimate role in forming belief. Ian Hacking, in The Emergence of Probability (1975), situated the Wager in the history of probability theory, showing that Pascal was applying his own mathematical invention to the most consequential of all decisions.
Legacy and Influence
Pascal's influence extends far beyond apologetics. In philosophy, he anticipated existentialism by two centuries. His analysis of 'diversion' prefigures Heidegger's concept of 'fallenness' (Verfallenheit) and Sartre's 'bad faith' (mauvaise foi). His insistence on the irreducibility of human existence to rational categories influenced the phenomenological tradition from Husserl onward.
In literature, Pascal's style - aphoristic, paradoxical, psychologically acute - influenced La Rochefoucauld, Nietzsche, Dostoevsky, and Kafka. His analysis of the human condition as simultaneously grand and wretched is the template for modern tragic humanism.
In theology, Pascal established a mode of apologetics - beginning with human experience rather than metaphysical proof - that has been developed by Kierkegaard, C.S. Lewis (whose Mere Christianity follows Pascal's psychological strategy), and Timothy Keller (The Reason for God, 2008).
Key Passages
Fragment 72 (Lafuma): 'Man is but a reed, the most feeble thing in nature; but he is a thinking reed. The entire universe need not arm itself to crush him. A vapour, a drop of water suffices to kill him. But, if the universe were to crush him, man would still be more noble than that which killed him, because he knows that he dies and the advantage which the universe has over him; the universe knows nothing of this.'
Fragment 277: 'The heart has its reasons, which reason does not know. We feel it in a thousand things. It is the heart which experiences God, and not the reason. This, then, is faith: God felt by the heart, not by the reason.'
Fragment 555: 'Know then, proud man, what a paradox you are to yourself. Humble yourself, weak reason; be silent, foolish nature; learn that man infinitely transcends man, and learn from your Master your true condition, of which you are ignorant. Hear God.'
Contemporary Relevance
Pascal's diagnosis of 'diversion' has never been more relevant than in the age of smartphones and social media, when the capacity to distract oneself from existential questions has been technologically amplified beyond anything Pascal could have imagined. His analysis of the human condition as characterized by restlessness ('All of man's misfortune comes from one thing, which is not knowing how to sit quietly in a room,' Fragment 139) speaks directly to contemporary anxiety, attention deficit, and the epidemic of loneliness.
The Wager has been revived in the context of artificial intelligence and existential risk. Nick Bostrom's 'Pascal's Mugging' thought experiment and the debate over whether to take low-probability, high-consequence scenarios seriously (asteroid impact, pandemic, superintelligent AI) echo the Wager's structure. The philosopher Peter Kreeft has argued that Pascal's approach - taking the consequences of being wrong seriously, even when certainty is unavailable - is the appropriate response to the great questions of existence.
