1312), son of Sancho El Bravo, and his wife Maria de Molina, is a figure of small note in Spanish history.
He owed his escape from the violence of competitors and nobles, partly to the tact and undaunted bravery of his mother Maria de Molina, and partly to the loyalty of the citizens of Avila, who gave him refuge within their walls.
In theology, Suarez attached himself to the doctrine of Luis Molina, the celebrated Jesuit professor of Evora.
Molina tried to reconcile the doctrine of predestination with the freedom of the human will by saying that the predestination is consequent upon God's foreknowledge of the free determination of man's will, which is therefore in no way affected by the fact of such predestination.
The only information at this period on the ornithology of South America is contained in the two works on Chile by Molina, published at Bologna in 1776 and 1782.
