Justus Lipsius

Justus Lipsius (born Joest Lips, in Dutch Jodocus Lips) was born in Overijse, in the Duchy of Brabant, in 1547, and died in Leuven in 1606. A philologist and humanist from the Spanish Netherlands, he is remembered as one of the most celebrated scholars of his age, often grouped with Joseph Justus Scaliger and Isaac Casaubon as the great literary scholars of the period. His lasting importance lies in his effort to reconcile ancient Stoicism with Christian belief.

He was educated by Jesuits in Cologne, who fostered his love of Latin and Greek literature, and then studied at Leuven. After early work on textual criticism he entered the service of Cardinal Granvelle, which took him to Rome for two years of study among Latin classics, inscriptions and manuscripts. In 1570 he taught at Jena, where he had to accommodate Lutheran expectations, and after stops in Cologne and Leuven he moved north. In 1579 the newly founded University of Leiden appointed him professor of history, and his eleven years there were the most productive of his career, producing his editions of Seneca and Tacitus and many works on politics and warfare.

His best-known book, De constantia, presents a practical Stoicism drawn chiefly from Seneca and compatible with Christianity: virtue means keeping reason steady in the face of fortune and passion. In his Six Books of Politics he argued that a state should recognise only one religion, a claim that drew criticism and that he had to qualify publicly. Around 1590 he left Calvinism and reconciled with the Catholic Church at Mainz, and afterwards settled in Leuven as a professor of Latin.

His influence was wide. His Christian Stoicism gave rise to Neostoicism, which reached writers such as Francisco de Quevedo. Some historians, notably Gerhard Oestreich, have linked his ideas about the disciplined, rational citizen to the emergence of the modern state, though this view remains contested. His name survives today in the Justus Lipsius building in Brussels, long a seat of European institutions.
