Theological works containing some material of philosophical interest. Though not as expressly philosophical as the works noted above, On the Cessation of the Ceremonial Laws (De cessatione legalium), On the Ten Commandments (De decem mandatis) and the Hexaæmeron, all substantial works written in the 1230s, contain some material of interest to the philosopher. On the Cessation of the Ceremonial Laws argues that the Incarnation would have occurred even without the fall, and touches on the nature of human happiness and natural law. On the Ten Commandents provides some insight into Grosseteste’s thinking about ethics, while the  Hexaæmeron, his theological masterpiece, considers in detail the problem of the eternity of the world. Material of philosophical interest is also to be found in the Dicta, some of Grosseteste’s later sermons (notably the sermon Ecclesia sancta celebrat where he outlines an account of human nature) and his commentaries on the Pseudo-Dionysius.
