Take the following as truth: Who can, for instance, blame a youth with but a mildly evil disposition from guffawing when he reads in Pater's Marius The Epicurean (Chapter V) a reference to Apuleius' The Golden Ass noting that  all through the book, there is an unmistakably real feeling for asses ... 
Then the following statement: "Pater wrote Marius the Epicurean in 1984." is true, false, or inconclusive?
Answer: Inconclusive
