It reads like a doctor's thesis (though it isn't one) -- and its market will be primarily the class room and reading clubs, as a springboard for more intensive reading along the lines of biography. Biography as the coming art, such is his theme. And to prove it he digs back into the history of biography, beginning with Plutarch, and stressing, in its development, English biographers primarily. Only four moderns are discussed at any length, -- Guedalla, Lytton Strachey, Gamaliel Bradford and Andre Maurois. Can't see a general market for this.
