In a new Apostolic Letter released on the day he would have turned 400, Pope Francis praises the âbrilliant and inquisitive mindâ of the French thinker Blaise Pascal.
By Joseph Tulloch
“A tireless seeker of the truth”.
Thatâs how Pope Francis defines Blaise Pascal, the French mathematician, physicist and philosopher born 400 years ago today.
The Pope has dedicated an Apostolic Letter to him, stressing his scientific brilliance, concern for the poor, and relentless search for God.
The letter
A key theme of Pope Francisâ letter is the âbrilliant and inquisitive mindâ of Pascal. A child prodigy, he made important breakthroughs in mathematics and, at age 19, invented an arithmetic calculator, a forerunner of the modern computer.
The Pope stresses that Pascal used his intellectual gifts to wrestle with âthe questions that troubled his ageâ, inventing, for example, the âfive-penny coachesâ system, the worldâs first public transport network.
The Holy Father goes on to praise Pascal â who, aged 31, underwent a conversion experience he referred to as the âNight of Fireâ â for his nuanced understanding of the role of reason in religious belief.
On the one hand, the Pope says, Pascal argued for the “reasonableness of faith in Godâ; on the other, precisely because of his own intellectual prowess, he also recognised reasonâs limits, and stressed the importance of responding with faith to Godâs call.
A final theme to emerge from the letter is Pascalâs attention to those less well-off than himself.
The Pope quotes Pascalâs words on his deathbed: âIf the physicians tell the truth, and God grants that I recover from this sickness, I am resolved to have no other work or occupation for the rest of my life except to serve the poor.â
âIt is moving,â Pope Francis writes, âto realize that in the last days of his life, so great a genius as Blaise Pascal saw nothing more pressing than the need to devote his energies to works of mercy.â
Cardinal Tolentino: Pope âprofound admirerâ of Pascalâs
At a press conference convened to present the Apostolic Letter, Cardinal Tolentino de Mendonça â the Prefect of the Vaticanâs Dicastery for Culture and Education â stressed that Pope Francis is a âprofound admirerâ of Pascal.
The Cardinal noted that the Pope has released (or is planning to release) a number of such Apostolic Letters, on figures, such as Dante Alighieri and Saint Therese of Lisieux, whom he judges âbeaconsâ for the contemporary world.
Pascal, the Portuguese Cardinal said, is one such beacon, because he âbrings everything togetherâ: science and faith, philosophy and mathematics, spirituality and a practical mindset.
He also stressed that Pope Francisâ letter, as well as discussing the well-known aspects of the French writerâs life, makes an original contribution in that it delves into lesser-known territory, such as his concern for the poor.
In response to a question about Pascalâs association with Jansenism, a controversial theological movement in the early modern Church, the Cardinal said that the French writer was âperfectly Catholic.â
