The philosophy taught in the church schools and theological training-grounds in the medieval period. Scholasticism was the dominant philosophical approach in Europe from perhaps the 11th until the 16th century, or the time of Abelard to that of Suárez. It combined religious doctrine, study of the Church fathers, and philosophical and logical work based particularly on Aristotle and his commentators, and to some extent on themes from Plato. Prominent scholastics included Aquinas, Buridan, Duns Scotus, and Ockham.
