French theologian, poet and Latinist, c. 1128-1202.
Fishburn and Hughes: "A French theologian and poet, whose extensive learning won him the title Doctor Universalis. He combined mysticism with rationality. Assuming that the principles of faith were axiomatic, he sought to refute heterodoxy on rational grounds. In a discussion of metaphors of the Universe, Borges quotes Alanus' famous formula: 'God is an intelligible sphere, whose centre is everywhere and whose circumference is nowhere' (TL 352)." (6)
