Alain de Lille (c.1128-c.1202) French theologian and poet

Alan of Lille was a French theologian and poet. He is sometimes called Alanus de Montepessulano.

He was born in Lille sometime before 1128. His exact date of his death is also unclear - research suggests between 14 April 1202 and 5 April 1203.

Although he was widely known during his lifetime there is not a great deal known about his personal life. He had a very widespread reputation during his lifetime and his knowledge caused him to be called Doctor Universalis.

As a theologian he was opposed to scholasticism in the second half of the 12th century. He claimed in order to understand religious truth and to know God,the wise must believe in faith.

His philosophy was a mixture of Aristotelian logic and Neoplatonic philosophy.

The is a long list of works attributed to him (See List of known works) but there are several Alains so it is uncertain how many of the works listed are actually his.
Notable works actually written by him include*The Plaint of Nature, Anticlaudiamus and the Art of Preaching.
