Bartolomé de Medina

Bartolomé de Medina was a Spanish Dominican theologian of the School of Salamanca. Born at Medina de Rioseco in 1527, he joined the Dominicans and studied at Salamanca under Francisco de Vitoria and Domingo de Soto. He spent most of his teaching career there, winning its principal chair of theology.

His theological writings were chiefly commentaries on Aquinas's Summa Theologica, in which he formulated probabilism, which permits following a solidly probable opinion even when the contrary seems more probable. He died at Salamanca around 1580.
