These speeches and essays were written over a period of twenty-four years. The fact that James did not collect and publish them himself in a single volume does not reflect on their intrinsic worth or on their importance in James's philosophical work, since they include some of the best known and most influential of his writings. All the essays, throughout their varied subject matter, are consistently and characteristically Jamesian in the freshness of their attack on the problems and failings of humankind and in their steady faith in human powers.
