Life
Domat was born at Clermont in Auvergne. He studied the humaniora in Paris, where he befriended Blaise Pascal, and later law at the University of Bourges.

However, as a supporter of a Cartesian juridical order, Domat endeavoured to found all law upon ethical or religious principles, his motto being "L'homme est fait par Dieu et pour Dieu"
