Erasmus à Paris.

La Sorbonne ou l'université Denis Diderot, c'est la question! The former sounds better, of course, for it's a well-known name. The latter on the other hand offers a master on "Identité, alterité" with quite an interest seeming programme. YES ! I'm thinking of studying in PARIS. I just don't know where.
To make matters more complicated there are different professors responsible for nominating Erasmus out-going canditates, so I don't know whether it's better to apply for both things or to settle for one. GAH! Desicions!
