Jean Arnauld

Jean Arnauld was a French philosopher and theologian of the 17th century. He predominantly lived in Reims and most of his work was focused on logic and the failure of reason, the topic for which he is best known. He was unrelated to Antoine Arnauld, although contemporaneous.

Life Arnauld was born into an influential, deeply cultured family in Reims. The exact date of his birth is unknown, and there is very little biographical written about him. He was born in 1580-1590 and died in 1645–1660. He studied in Paris L' Erreur de Logique is his most widely know book and discusses the failings of logic and how some sense of faith or intuition is sometimes needed to disprove things that have seemingly be proven by logical arguments. It also discusses the way logic is often used to argue things even when the conclusions are actually logical fallacies. However, his precise arguments are not known in full as the text is no longer extant and so all that remains is a summation of his argument and some passages in secondary sources. Raison et Dieu (Reason and God) was published in 1640 in Paris.
