The work for which Pascal is best remembered, the Pensées (‘Thoughts’), was never meant to terrify anyone except himself: it was a collection of disorderly notes for a more systematic theological treatise which he never managed to write. Had he completed this work, it would probably have become less interesting. Instead, he left us one of the most mysterious texts in literature, a passionate outpouring largely written to try to ward off what he saw as the dangerous power of Montaigne’s Essays.
