Platonic Academy
The title of Drummond's book refers to the "later" Platonic Academy, which was, in fact, not so much Platonist as Sceptical in orientation, based on the work of Pyrrho the Sceptic and later followers of Pyrrho such as Carneades. "Academical Questions" is a work in the Sceptic tradition, in this case influenced by the Sceptical Scottish philosopher David Hume.
