Blaise Pascal: The Man Who Made the Modern World
'Readable and expert - a brilliant guide to the life and thought of 17th century Europe's supreme polymath'
Tom Holland
'A richly detailed account of Pascal's life and times, which displays an energetic sympathy for Pascal's startling combination of intellectual precocity and humble faith.'
Rory Stewart
'A beautiful, accessible account of one of the era's most remarkable lives'
Katherine Rundell
He lived for just 39 years, yet Blaise Pascal was one of the most remarkable and creative figures of the seventeenth century.
He is known for his famous (though often misunderstood) argument 'the Wager', but there's so much more to him than that. Pascal can lay claim to have built an early version of the modern computer, done ground-breaking work in mathematics and geometry, invented urban bus transport and virtually invented probability theory. He also produced one of the most haunting and effective works of Christian apologetics ever written. He is a major intellectual figure at the beginning of the modern age who blends together in his own person and thinking issues that are critical to our age. Blaise Pascal is therefore a crucial not just in the history of European thought, but for how he can shed light on our many contemporary debates.
From science to scepticism; mystical experience to distraction; religion to politics, self-love and death, Pascal's thinking was far-reaching. In this captivating biography, Graham Tomlin explores Pascal's short but extraordinary life, and the sweeping impact and relevance of his ideas to the modern world.

Easily one of my favorite books of the year. Tomlin not only offers insight to Pascal and his times but also applies those lessons for today in ways that stir the affections and also the intellect.

August 17, 2026Few philosophers stand at the intellectual crossroads of humanity like Blaise Pascal. Few are so poignant, centuries after their death; few stir the heart as much, and few ask the questions that Pascal asks. Nearly a universally beloved figure, cited by Christian thinkers such as T. S. Eliot and by atheists such as Friedrich Nietzsche, in many ways, Pascal acts as the catalyst for the modern debates raging today and which have raged in the centuries following his brief but influential life. The Enlightenment vs. Romanticism; Christianity vs. rampant atheism; skepticism or rationalism; predestination or free will? In this newest biography of this prominent intellectual, author Graham Tomlin places Pascal within his intellectual and cultural time, yet posits that his ideas are as relevant in our age as they were to his. Mathematician, physicist, apologist, and Christian thinker, Pascal inhabited a world in which the old synthesis of faith, philosophy, and nature was beginning to fracture, even as the new scientific enterprise was taking shape.
Tomlin argues that it was part of the collapse between the scientific world and the metaphysical brought about by Descartes that led to the latter skepticism of figures like David Hume. The problem with this is that Descartes was a rationalist; that is, someone who believed not in the empirical or scientific world, but in the rational world. Whereas Hume certainly collapsed the two into one, Descartes did not. Tomlin actually points this out earlier in the book when he writes that “Descartes’ vision of human life was deeply intellectual, almost as if the body does not really matter.” This suggests that Pascal, in science if not in metaphysics, was far more of an empiricist than a rationalist, which helps to explain both Descartes’ disdain for Pascal and Pascal’s contempt for Descartes. Tomlin’s point on collapsing the empiric world with the metaphysical, or the scientific with the religious, is certainly worth taking into consideration. He argues that had this collapse not occurred and had Pascal’s separation of the two been considered, perhaps this would have prevented the rise of modern atheism.
The problem with Pascal’s division, however, is precisely the one that Thomas Aquinas had to dispute with five centuries earlier in Latin Averroism and which would again manifest itself post-Aquinas in nominalism. This is the division between science or philosophy and theology, which led to the creation of two completely separate worlds which had nothing to say about each other. Although Pascal certainly did not go as far as to say that the two did, or could, contradict each other, separation certainly leaves this possibility open to the point where reason loses all point. Tomlin also argues that when seeking evidence for God from a scientific standpoint, Pascal’s contemporaries could find nothing unambiguous, and so embraced atheism, yet this presupposes that those who searched for unambiguous evidence were coming from the empiricist viewpoint: seeing science, or that which could be proven by the senses, as the only things which could be considered “unambiguous.” This ignores the teleological, ontological, and other classical arguments for the existence of God which are by no means unambiguous, but which would, in turn, only work if one assumes the Thomistic understanding that, though it begins with the senses, reason can lead to metaphysical conclusions.
An important distinction which Tomlin makes is that Pascal did believe that there was room for reason and argumentation. “Similarly, he thinks there is a role for reason and evidence in confirming the truth of the Christian religion – he just doesn’t think it can get you there in the first place.” Pascal believed that Christianity was the religion which best fit the facts, though there is still a question about whether Pascal believes the facts fit Christianity. Pascal also argued that there were things that had to be accepted in what Kant would call a priori, that is, to reason at all, or to conduct experimentation, they must be assumed for anything else to be concluded. This is true. Aquinas would call these first principles or the principles of practical reasoning. Tomlin concludes that “The scientific enterprise is not wholly lacking in faith either.” If by faith he means that which cannot be proven, then he is, of course, correct, yet classically, faith has been seen as more than that. Writes Paul in Hebrews 11, “Faith is the substance of things hoped for, the evidence of things not seen.” Christ also commands us to have faith in him, yet also grants that not everyone does, which grants faith a certain level of freedom, one which would simply not apply to the first principles, which are not a matter of choice: you cannot reject them, for by rejecting them you at the same time affirm them.
On the other side of the dilemma, Tomlin writes that “Pascal stands as one of the key figures at the start of the modern project of experimental science, who sees no incompatibility at all between faith in the God of Jesus Christ and a total commitment to the scientific enterprise and wherever it takes you.” It is an interesting and helpful conclusion, yet one struggles to see how Pascal’s assertion that reason can confirm but never establish Christianity avoids reducing faith to a fundamentally non-rational attribute; if reason cannot furnish any positive grounds for belief prior to belief itself, there is little reason for supposing that any positive grounds will be submitted post-belief. One may argue that faith enables one to see in a new light that which was not seen before; it would hardly seem to fit the Pauline description of faith as “substance” and “evidence.”
The author also wades into the debate over Jansenism which preoccupied Pascal and many others of his time. This theological movement could be loosely associated with Calvinism in that it stressed the sovereignty of God over human fate, yet, as the Reverend makes clear, it was entirely distinct from Calvinism in its commitment to remaining within the confines of the Roman Catholic Church. The Catholic Church, on the other hand, was committed with equal rigor to distancing itself from the Jansenists. The Court of Louis was hostile to them; Catholic scholars committed still to the Jesuits would attack them in the news brutally, showing no mercy and no nuance to the valid points made by many of the Jansenist theologians. Without wading into the centuries-long debate over free will and predestination, Tomlin clearly and convincingly shows us how Jansenism saw the world and what they were ready to do about it, while also showing how Pascal played a vital role in the defense of this group, a group with which he would eventually break.
The book discusses also Pascal’s conception of a hidden God. This idea helps explain why he did not believe that reason, or human reason, could lead to a true knowledge of God. It doesn’t, for the record, prove that Pascal is right, but it shows a surprising internal consistency in that if God is hidden, then reason loses all effect in leading the repentant sinner to grace. His argument is that God hides himself from those who do not wish to accept him, thus making it impossible for them to find him, and making reason useless in the process. Reason, for Pascal, is helpful for the believer, yet ineffectual for the unbeliever for precisely this reason. For reasons outlined above and below, it seems that this answer is a bit too simplistic, yet his broader point stands. Indeed, it seems to affirm some sort of human freedom, despite his Calvin-like belief in the sovereignty of God over human fate, for he believes that for those who do not seek Him, they shall not be sought by Him.
Where Tomlin succeeds marvelously is in placing Pascal within his time. If we look at his ideas, or the ideas of any other philosopher for that matter, as simple ideas, and leave out the context, that makes the ideas no less true or false, but it certainly decreases our ability to properly understand why these ideas were held. Tomlin helps us understand, not only by explaining Pascal’s life - the fact that he was unhealthy for much of his life contributed significantly to his rejection of Descartes’ mind-body dualism - but also those of his contemporaries. One of the most fascinating of these is Michel de Montaigne. Perhaps Tomlin would dispute this, but Pascal and Montaigne seem similar in one significant way: like Pascal, Montaigne seems to be very focused not on the abstracts of Aristotelianism or Platonism, but on the experiential, particularly when it comes to the self. Like Pascal, he is less concerned with the objective reality and more concerned with how we relate to that reality. Indeed, at first glance, the two philosophers seem to be on the same path; certainly, they have started at the same point. These three men are the key to understanding the French philosophical world of the seventeenth century. Descartes believes that belief can be achieved: belief rooted not in itself, but in reason; this belief, posits Descartes, corresponds to reality. Pascal is far less certain. In a way which the author does not state but which could be easily concluded from reading the book, Pascal is the intermediary between the two extremes of Descartes and Montaigne. He too believes that certainty can be attained, but he seems far less preoccupied with the importance of certainty and more preoccupied with why the certainty is necessary in the first place. On the other hand, Montaigne does not believe that certainty is possible, and if it was, he doesn’t really care. It is more of a utilitarian, pragmatist approach, one which Pascal seems to echo in The Wager, in his own way. Writes Montaigne, “Our intellectual faculties and our senses have no foundation to stand on but only fly about in the wind.” Further, Montaigne claims that Christianity itself “did not come to us through reasoned arguments or from our own intelligence; it came to us from outside authority, by commandments.” This is indeed one of the many reasons why the Protestant Reformation was carried out. While Luther would likely have agreed far more with Pascal than with Aquinas on reason and faith - he famously called reason “Aristotle’s whore” - other Reformers would have been different. Calvin was friendly to reason; Melanchthon friendlier still. The Reformers understood that the lack of reasoned argumentation came from a lack of reading of Scripture itself. This is why there was such an emphasis on the printing of the Bible in the lingua franca: because argumentation ultimately could lead to the demonstration of truth claims, and because, as Paul himself instructs, we are to “test all spirits.” The author distinguishes Montaigne and Pascal in a significant area, and that is their treatment of life and the afterlife. Montaigne argued for methods of contemplation which would lead one to finally lose all angst and enable one to enjoy life to the fullest.
Pascal rejects this solution, in a way that more Christians today likely should as we face a Montaigne-like hedonism: for Pascal, angst comes not only from the temporal and should be relieved not because of the temporal, but because of the eternal. It is not a matter of living better in this life, for Pascal, but of being certain about the other. In this, both Thomistic Christians and Pascaline Christians can agree. We may differ on where such a certainty comes from, yet we must agree that the achievement of such certainty is of vital importance. The enduring debate between Descartes, Pascal, Aquinas, Montaigne - and to this we should likely add Augustine and Luther as well - will likely never be fully solved, but with Pascal, we can discover that it is impossible to be fully indifferent to the question of certainty.

Blaise Pascal died in 1662. He lived a relatively short life of 39 years, but he packed a lot into that life, making some momentous contributions to Physics, Mathematics and to Philosophy. He was also surprisingly modern in some of his thinking. He was among the first to wear his watch on his arm, as a wrist watch. And at the end of his life he developed one of the first bus companies, to help the poor travel across the city of Paris.
Pascal was an extraordinary thinker who deserves to be much better known. He comes across with some social awkwardness, but also with a passion for social justice which led him to try to help the poor and disadvantaged.
His mind was constantly occupied, jumping about and making connections which no one else had thought of. For example, at the age of 19 he invented the Pascaline, which became the first calculating machine.
He also planned and carried out one of the first examples of a scientific experiment. He postulated that the air had a weight which would exert different pressures at different altitudes. He then sent people up a mountain with a tube of mercury to confirm that that really was the case.
Pascal also contributed to philosophy and theology. He is well known for his ‘wager’, which is usually interpreted as an argument that it is better for a person to believe in God, rather than risk the consequences of failing to do so. One of the interesting aspects of this book is that it looks closely at Pascal’s wider writings, and then it suggests that it is an oversimplification to think of the wager as an argument for God’s existence.
The author shows that Pascal had a sophisticated understanding of how and why people adopt religious beliefs. He thought that arguments were largely irrelevant, and that people believed due to deeper emotional and psychological factors. It is those deeper factors which his wager is trying to address. So, reading it as an ‘argument’ is potentially to completely misunderstand Pascal’s viewpoint.
That is a very interesting reading of Pascal, especially as the author explains it by drawing heavily upon Pascal’s wider writings.
Some lives of Pascal get bogged down in the theological intricacies involved in Pascal’s dealings with the Jesuits and Jansenists. One of the particularly commendable features of this book is that it manages to narrate those complicated issues in a very focused and accessible way.
This is partly because the author made a thoughtful decision to focus each chapter around specific themes. The book still narrates Pascal’s life in a chronological way, but there are specific chapters dealing with science, theology (etc). This makes it easier for readers to focus on specific areas of interest, and it also means that the book has a tight and focused structure.
One of the things which this book does very well, is that it sets Pascal into his historical context, with an excellent analysis of contemporary events and personalities. It also ranges across later commentators, noting how people like Foucault and Nietzsche (among others) have reflected on Pascal.
There are occasional minor errors in the text. For example, in chapter 16 (at 87%) ‘viaticum’ is confused with ‘mass.’ (Viaticum is the communion host which is consecrated at mass. It is not the mass itself, as the book seems to assume). But tiny errors like that are inconsequential in what is otherwise a masterful portrayal of a complex figure in a complicated era.
Overall, this is a well-researched and well-produced account of a fascinating individual. It is well-written to be accessible to readers from any background, and it includes around 10% of the text as notes and indices for academic readers.
(These are honest comments on a digital ARC (Advanced Review Copy) version of the text).

Very nice book on the man behind the science & mathematics… with a main focus on his Christian faith and philosophy.

This is the best biography of BP available in English, far superior to O'Connell's, which I found rather sterile. Tomlin found a way to tell Pascal's story, which isn't overtly exciting, in a compelling and engaging manner and does justice to him as a scientist, mathematician, inventor, and theologian. His exposition of his Penses, in general, and The Wager, in particular, is outstanding - equal to Kreeft (Christianity for Modern Pagans), and in some way, better. And I deeply appreciated Tomlin's explanation of Pascal's relationship to Augustine, Jansenism, and Roman Catholicism. Since he is not a Roman Catholic, he didn't have a dog in that fight, and wasn't compelled to affirm the condemnations of 4 popes: Urban VIII, Innocent X, Alexander VII, and Clement XI. In fact, the Pascal that emerges from the Penses, The Provincal Letters, etc., which is deeply indebted to Augustine, has much in common with English (and American) Puritanism, as well as Evangelicalism, at least in terms of their: 1) robust doctrine of the Fall and Original sin; 2) the absolute need for effectual grace; 3) moral seriousness and mortification; 4) a critique of nominal, cultural Christianity; 5) the important of spiritual habits and the means of grace. Those who love C.S. Lewis will love Pascal. The same is true of Augustine. The same is true of Nietzche, and in some ways, Luther as well. All superb theologians of humanity and the human heart.
The best book I've read this year, and quite possibly, in a couple of years.

A comprehensive book about an amazing man. Scientist, inventor, theologian, mathematician, philosopher and a man of lived-out Christian character. Pascal, who died young at the age of 39, lived in 17th century France. He proved the existence of the vacuum, the weight of air and is the originator of modern probability theory.
He also invented modern public transportation as a means of serving the poor, gave up is home to an an indigent family while also inventing the first mechanical calculator. It is no surprise that one of the early computer programming languages was named after him.
He centered himself on his Christian belief, especially after a conversion experience he described as the Night of Fire. He struggled with some Catholic (particularly Jesuit) doctrine and aligned himselve with the Jansenists who, while rejecting Protestantism, stressed the grace of God that was missing from Catholic teaching.
He may be best known for the Pensées (literally "thoughts") that were the outline of an apologetic for belief in Christianity. He rejected rationalism, which many of the traditional apologetics of his day promoted, as an inadequate way to find God. However, he was not anti-reason. Famously he wrote "Men despise religion. They hate it and are afraid it may be true. To cure this we have to first show that religion is not at all contrary to reason. It is worthy of reverence and respect. Next make it attractive. Make good men wish it were true. And then show that it is true. Worthy of respect because it really understands human nature. Attractive because it promises true good."
Blaise Pascal is also famous for "The Wager" which has been misunderstood by so many, including by Voltaire, almost since he first wrote it. Common misconceptions are that it is arguing that it is better to just believe Christianity because you have more to gain and less to lose. This is at the very least reductionist, and actually misses his point completely. To understand what Pascal really meant read the book. If you're interested in history generally, or would like to learn more about a slice of French history, or to read about an amazing mind and his discoveries, or to understand one of the great philosophers and his reasons for life-transforming belief in God, also read this book.
A couple more quotes, from the book and Blaise Pascal himself:
- For a generation that is bombarded with distractions: "the sole cause of man’s unhappiness is that he does not know how to stay quietly in his room."
- For our present world that seems to end up with doubtlful leaders: ‘the power of kings is founded on the reason and the folly of the people, but especially on their folly."
- And a snippet from 'The Wager': "I should be much more afraid of being mistaken and then finding out that Christianity is true than to have been mistaken in believing it to be true. "
He also invented modern public transportation as a means of serving the poor, gave up is home to an an indigent family while also inventing the first mechanical calculator. It is no surprise that one of the early computer programming languages was named after him.
He centered himself on his Christian belief, especially after a conversion experience he described as the Night of Fire. He struggled with some Catholic (particularly Jesuit) doctrine and aligned himselve with the Jansenists who, while rejecting Protestantism, stressed the grace of God that was missing from Catholic teaching.
He may be best known for the Pensées (literally "thoughts") that were the outline of an apologetic for belief in Christianity. He rejected rationalism, which many of the traditional apologetics of his day promoted, as an inadequate way to find God. However, he was not anti-reason. Famously he wrote "Men despise religion. They hate it and are afraid it may be true. To cure this we have to first show that religion is not at all contrary to reason. It is worthy of reverence and respect. Next make it attractive. Make good men wish it were true. And then show that it is true. Worthy of respect because it really understands human nature. Attractive because it promises true good."
Blaise Pascal is also famous for "The Wager" which has been misunderstood by so many, including by Voltaire, almost since he first wrote it. Common misconceptions are that it is arguing that it is better to just believe Christianity because you have more to gain and less to lose. This is at the very least reductionist, and actually misses his point completely. To understand what Pascal really meant read the book. If you're interested in history generally, or would like to learn more about a slice of French history, or to read about an amazing mind and his discoveries, or to understand one of the great philosophers and his reasons for life-transforming belief in God, also read this book.
A couple more quotes, from the book and Blaise Pascal himself:
- For a generation that is bombarded with distractions: "the sole cause of man’s unhappiness is that he does not know how to stay quietly in his room."
- For our present world that seems to end up with doubtlful leaders: ‘the power of kings is founded on the reason and the folly of the people, but especially on their folly."
- And a snippet from 'The Wager': "I should be much more afraid of being mistaken and then finding out that Christianity is true than to have been mistaken in believing it to be true. "

What:
====
A detailed examination of significant parts of Pascal’s rather short life (he was under 40 when he died), his contemporaries and the religious milieu of which he was one (rather vocal) part. We get more theology than biography in this book, bear that in mind.
Some High Points, Reasons to Read:
============================
We get an in-depth understanding of the complicated religious environment that was at play in France in the second half of the 17th Century. The theology and priorities of the Jesuits are set in clear contrast to other groups. As usual, the game is to get any minority who disagrees with you or calls out your failings certified as heretics. Nothing new under the sun there! (Either for Jesuits or people in general.)
Though the author goes on a bit too long, we do get a proper explanation of Pascal’s Wager in its full and right context - which is quite a bit more subtle and complex than the over-simplified version you can find most places. The author makes a good case that Pascal never intended or imagined his Wager as an irrefutable argument in any sense.. His real goal was apologetics and his argument (of which the Wager is one piece) was complex and intricate.
Pascal is an interesting character though I can imagine his friends and relatives might have frequently found him to be “too much”. This book does a good job of placing Pascal’s later focus on faith and theology in a full context.
Too often, Pascal gets summed up as “brilliant mathematician and scientist who became a religious fanatic and died young”. This book paints a much more complete and far more accurate picture of the man.
If you want to see a minority view of faith within French Catholicism, Pascal and the Jansenists he was associated with (always a complex relationship) give a very interesting twist on the topic, especially in contrast to the much more commonly seen (and politically connected) Jesuit perspective.
Weaknesses, Reasons to Skip
=======================
The author does *not* deliver on the title’s premise in his book. In no sense did Pascal “make” the modern world.
This book is largely about Pascal’s theology and work on apologetics. It contains a fair amount of biographical content and certainly spends time on his mathematics and physics contributions (including his mechanical calculator!), but I wouldn’t describe it as a biography.
I frequently fell asleep reading this - not a good sign of the book’s ability to engage a reader, or at least, this reader. But, I kept coming back to it and finished it.
Pascal died young and as such, we are dealing with unfinished business in his writings and much of the early editing of his work posthumously was done by others with an agenda. That might be unsatisfying for some.

Book Review: Blaise Pascal: The Man Who Made the Modern World by Graham Tomlin
Graham Tomlin’s Blaise Pascal: The Man Who Made the Modern World is a masterful intellectual biography that illuminates the extraordinary life and enduring legacy of the 17th-century polymath. In this meticulously researched yet accessible work, Tomlin captures Pascal’s dual brilliance as a scientific pioneer and profound religious thinker, arguing convincingly for his underappreciated role in shaping modernity. The book balances rigorous scholarship with narrative flair, making it equally valuable for academics and general readers interested in the intersection of faith, reason, and innovation.
Tomlin’s greatest achievement lies in synthesizing Pascal’s multifaceted contributions—from the invention of the mechanical calculator to the formulation of probability theory and his seminal Pensées—into a coherent portrait of a restless genius. The author excels at contextualizing Pascal’s scientific breakthroughs within the broader intellectual ferment of the Scientific Revolution, while also exploring how his late-career religious awakening influenced his philosophical outlook. Particularly compelling are the chapters dissecting Pascal’s Wager, where Tomlin elucidates its logical structure without oversimplifying its theological nuances.
The biography adopts a roughly chronological structure but thematically clusters Pascal’s endeavors, allowing for deep dives into specific domains. While this approach highlights the remarkable breadth of his achievements, some transitions between scientific and theological discussions feel abrupt. Tomlin might have strengthened the work by more explicitly tracing how Pascal’s mathematical mind informed his later existential reflections. Nevertheless, the prose remains engaging throughout, with vivid depictions of Pascal’s Parisian milieu and insightful analyses of his correspondence with contemporaries like Fermat and Descartes.
Rating: 4.7/5
Section Scoring Breakdown:
-Biographical Depth: 5/5 – Exhaustively researched with fresh interpretive angles
-Interdisciplinary Synthesis: 4.5/5 – Seamlessly connects science/philosophy/theology
-Narrative Flow: 4/5 – Occasionally uneven pacing between technical and reflective passages
-Modern Relevance: 4.8/5 – Persuasive case for Pascal’s contemporary significance
-Accessibility: 4.5/5 – Clarifies complex concepts without dilution

This book is exhausting. No, strike that. I am exhausted. But not so much by this book, but rather by reading about the life of Pascal. This guy lived to be only 39 (eight years younger than I am now), but he managed to cram more into those few years than most people could in five lifetimes. He was the ultimate overachiever and a total natural at physics, math, and philosophy.
What really surprised me was how much of a trendsetter he was. Did you know he wore one of the first-ever wristwatches? He even started a bus company for the poor in Paris. This he did late in life while suffering and in pain and while practically on his deathbed. The man's brain never seemed to shut off. At only 19 years old, he built the Pascaline, a mechanical calculator that basically made the abacus obsolete.
Pascal wasn't just a "book smart" guy, either. When he had a theory about air pressure, he didn’t just write it down; he sent people hiking up a mountain with tubes of mercury to prove it. It was like a giant 17th-century "flex." I can almost see him smirking and saying, "See? I told you so."
Most people know him for "Pascal’s Wager," which is often boiled down to a simple logic puzzle about whether or not to believe in God. But Tomlin’s book shows that the wager, when seen in context, was way more sophisticated than that. He wasn’t just drawing a flowchart for your soul; he really understood human psychology and the deep emotions that drive people toward faith. For him, belief wasn't about winning a debate; it was about the struggle of being human.
It’s incredible to see the range of his mind. He invented probability theory (which is why we have modern statistics, the only math class back in high school I didn't absolutely hate), and he proved that a vacuum could exist in nature.
Despite being a genius, he had a huge heart. Near the end of his life, he gave up his own house to a poor family and dedicated himself to helping others. He seemed to realize that even the most brilliant mind is nothing without compassion. To me, that’s the real takeaway: Pascal didn't just leave us with great ideas; he left us with a reminder to use our talents to make the world a better place.

I have had a 25-year fascination with Blaise Pascal, and this book did nothing but nurture my admiration even more. He applied his fecund mind to so many topics and discovered the vacuum, pioneered computation, founded probability theory and conic sections, and wrote one of the most enigmatic yet persuasive defenses of Christianity's reasonableness. Any book that helps me swap my wits with his, even if only by a little, helps me become better at so many levels.
It's too much to ask any one book to capture all of Pascal's genius, and this book expectedly falls short. Written by a theologian, it focuses on Pascal's religious identity and does not enter into the history of science much, other than basically in passing. From a biographical perspective, that's unfortunate because religious folks, too, need to learn to connect science and religion in today's world. Understanding how Pascal unified them in one person better could dissipate some antagonism popularly portrayed.
As a spiritual biography, this book does an excellent job chronicling Pascal's journey from an ambitious scientist to his famous mystical experience in his "Night of Fire." It shows how he enters into the controversies of his day without being defined by them. It tells of his association with Jansenism and his sister's nunnery, both of which ran afoul of the Roman Catholic hierarchy. Finally, it shows his saintly heart in associating with the poor, not the salons, as his life waned.
Such spiritual drama illustrates the stuff of humble genius, and this book offers readers a chance to meet wits and spirits with this great luminary. Anyone looking to grow as a person - whether or not they follow Pascal at every point - can benefit from wrestling with this great mind. Even those who disagreed with him most - Voltaire and Nietzsche - agree with the supreme value of Pascal's mind. And of course, traditional Christians, especially those in the Augustinian/Reformed camps, will benefit from Pascal's keen observations on human life. I'm grateful to have spent time perusing these pages.

Tomlin gives us here a comprehensive biography of one of the 17th century’s most important thinkers, clearly positioning him in his place and time and explaining as accessibly as possible his scientific, mathematical, philosophical and religious achievements and ideas. I knew very little about Pascal until I embarked on this book, really little more than his famous wager, and I am now so much more knowledgeable. I can’t pretend to have followed all the maths and science, but that is my problem not the author's. Although the book focusses more on Pascal’s mind and work than the life, there’s still much excellently researched biography here, and I found the book an absorbing if sometimes challenging read.

informative and easy to read
I knew very little about Pascal but saw this book highly reccomended. The author does a great job of explaining the context Pascal was living in, so that his writings make a lot more sense. Some parts were a little repetitive, and because it was thematic rather than chronological it was at times a little confusing when different events occurred, but overall was a lot easier to read than I thought it would be, and really an enjoyable read.

Readable for those both casually and academically interested in the life of Blaise Pascal, the author sets the background with what is happening in the world as well as telling his life in sections based loosely chronologically, but also themed. I enjoyed it a lot more than I expected!
Thank you to NetGalley and the publisher for an ARC.

Tomlin does an excellent job covering the short life of Pascal. His contributions to thinking, science and religion are incredible given his short life, and the author does a great job of bringing these accomplishments to the modern age. I do wish there was a little more discussion on his scientific and mathematical achievements.

Best book I’ve read this year. Written in a very engaging and easy to read style and yet getting to the heart of Pascal, his thinking, theology, personality and controversy. I was challenged and inspired by this.

Content is good but the flow and non linear story telling was hard to follow for me. Content was cool!
