Gilbert de la Porrée (zhēlbĕrˈ də lä pôrāˈ) [key], 1076–1154, French scholastic philosopher, b. Poitiers. He taught for 20 years at Chartres, where he was for some time chancellor. He later lectured at Paris. In 1142 he was made bishop of Poitiers. He was twice accused of heresy. Gilbert's works— De sex principiis, an elucidation of Aristotle's last six categories, and his commentary on the De trinitate ascribed to Boethius—reveal his somewhat obscure position in scholastic realism, to which he adhered in a moderated form.
