​ALAIN DE LILLE [Alanus de Insulis] (c. 1128–1202), French theologian and poet, was born, probably at Lille, some years before 1128. Little is known of his life. He seems to have taught in the schools of Paris, and he attended the Lateran Council in 1179. He afterwards inhabited Montpellier (he is sometimes called Alanus de Montepessulano), lived for a time outside the walls of any cloister, and finally retired to Cîteaux, where he died in 1202. He had a very widespread reputation during his lifetime and his knowledge, more varied than profound, caused him to be called Doctor universalis. Among his very numerous works two poems entitle him to a distinguished place in the Latin literature of the middle ages; one of these, the De planctu naturae, is an ingenious satire on the vices of humanity; the other, the Anticlaudianus, a treatise on morals, the form of which recalls the pamphlet of Claudian against Rufinus, is agreeably versified and relatively pure in its latinity. As a theologian Alain de Lille shared in the mystic reaction of the second half of the 12th century against the scholastic philosophy. His mysticism, however, is far from being as absolute as that of the Victorines. In the Anticlaudianus he sums up as follows: Reason, guided by prudence, can unaided discover most of the truths of the physical order; for the apprehension of religious truths it must trust to faith. This rule is completed in his treatise, Ars catholicae fidei, as follows: Theology itself may be demonstrated by reason. Alain even ventures an immediate application of this principle, and tries to prove geometrically the dogmas defined in the Creed. This bold attempt is entirely factitious and verbal, and it is only his employment of various terms not generally used in such a connexion (axiom, theorem, corollary, etc.) that gives his treatise its apparent originality. Alain de Lille has often been confounded with other persons named Alain, in particular with Alain, archbishop of Auxerre; Alan, abbot of Tewkesbury, Alain de Podio, etc. Certain facts of their lives have been attributed to him, as well as some of their works: thus the Life of St Bernard should be ascribed to Alain of Auxerre and the Commentary upon Merlin to Alan of Tewkesbury. Neither is the philosopher of Lille the author of a Memoriale rerum difficilium, published under his name; and it is exceedingly doubtful whether the Dicta ​Alani de lapide philosophico really issued from his pen. On the other hand, it now seems practically demonstrated that Alain de Lille was the author of the Ars catholicae fidei and the treatise Contra haereticos.
The works of Alain de Lille have been published by Migne, Patrologia latina, vol. ccx. A critical edition of the Anticlaudianus and of the De planctu naturae is given by Th. Wright in vol. ii. of the Anglo-Latin Satirical Poets and Epigrammatists of the Twelfth Century (London, 1872). See Hauréau, Mémoire sur la vie et quelques œuvres d’Alain de Lille (Paris, 1885); M. Baumgartner, Die Philosophie des Alanus de Insulis (Münster, 1896). (P. A.)
