 About 1640, he joined a small group of solitaires who lived in the countryside near Port-Royal and were associated with the convent. They included Pierre Nicole, Claude Launcelot, and Sacy. The solitaires initiated the petites écoles de Port-Royal which continued in various locations from the late 1630s until 1660. Their students included the dramatist Jean Racine. Later on, Arnauld cooperated with Sacy in the first important French translation of the  Bible.[1]  He also co-authored the Grammaire générale et raisonnée with Lancelot and La Logique ou l’Art de penser (hereinafter Logic), with Nicole. All of these collaborative projects had their origins in the petites écoles. Blaise Pascal was closely associated with the solitaires beginning in 1655.
