Maurois at his gayest and wittiest in a different genre, a parody of mankind in general, and specifically in an American university. Dumoulin takes a chair at a university for a year and through a colleague becomes involved in the invention of a thought-reading machine, ""Psiki"" which drastically influences university activities for a time. After a brief flare of commercial success, the interest of the public wanes. There is both satire and philosophy presented in frivolous, fantastic manner. Not important but good entertainment.
