pubOne.info present you this new edition. Most of the chapters which make up the present volume have already appeared, in earlier versions, in certain magazines; and to the editors of The Forum, The North American Review, The Smart Set, and The Bookman, I am indebted for permission to republish such materials as I have culled from my contributions to their pages. Though these papers were written at different times and for different immediate circles of subscribers, they were all designed from the outset to illustrate certain steady central principles of dramatic criticism; and, thus collected, they afford, I think, a consistent exposition of the most important points in the theory of the theatre. The introductory chapter, entitled What is a Play? , has not, in any form, appeared in print before; and all the other papers have been diligently revised, and in many passages entirely rewritten.
