Albert played an essential role in the diffusion throughout Italy and central Europe of Parisian ideas which bore the mark of Buridan's teachings, but which were also clearly shaped by Albert's own grasp of English innovations. At the same time, Albert was not merely a compiler of the work of others. He knew how to construct proofs of undeniable originality on many topics in logic and physics.
