In the beginning of The Great Divorce, C.S. Lewis' narrator states:
However far I went I found only dingy lodging houses, small tobacconists, hoardings from which posters hung in rags, windowless warehouses, goods stations without trains, and bookshops of the sort that sell The Works of Aristotle.
I am assuming he means the bookstores were basic and catered to the needs of schoolchildren. Are there any other thoughts on what sort of bookshops sell The Works of Aristotle? To what purpose might Lewis refer to Aristotle at this point in the book?
