Siger of Brabant and Thomas Aquinas on Divine Power and the Separability of Accidents.

The author reflects on the contrasting philosophies of Siger of Brabant and Thomas Aquinas on the concepts of divine power and separability of accidents. He cites that Siger believes that a primary cause cannot produce the effect of the secondary cause without the secondary cause while Thomas Aquinas believes that God operates in things in such a way however that things have their own operations. The author mentions Duns Scotus who believes in divine omnipotence which is understood as the ability on God's part to produce on his own any effect that he does with a secondary cause.
