This book looks at Kierkegaard with a fresh perspective shaped by the history of ideas, framed by the terms romanticism and modernism. 'Modernism' here refers to the kind of intellectual and literary modernism associated with Georg Brandes, and such later nineteenth and early twentieth century figures as J. P. Jacobsen, Nietzsche, Dostoevsky, Ibsen (all often associated with Kierkegaard in early secondary literature), and the young Georg Lukacs. This movement, currently attracting increasing scholarly attention, fed into such varied currents of twentieth century thought as Bolshevism (as in Lukacs himself), fascism, and the early existentialism of, e.g., Shestov and the radical culture journal 'The Brenner' (in which Kierkegaard featured regularly, and whose readers included Martin Heidegger).
