  Before Grosseteste, Aristotle's text was considered very difficult, both in doctrine and in language, and it seems to have caused some concern because of its apparent disagreement with the dominant Augustinian theory of knowledge. Grosseteste not only explained the book clearly, but also reconciled it with Augustine by treating demonstration as the means by which a fallen humanity must come to knowledge of the world. Augustine's Neoplatonic account of knowledge is reserved for our restored or supernaturally assisted nature in its contemplation of God, or of the natural world in God. No doubt, Grosseteste's position as a well-known and conservative Bishop helped to legitimize the science of demonstration for his more conservative readers.
