No mystic experience is continuous and permanent. All mystic experiences come to man in broken fragments. It is therefore the task of philosophy to turn them into a coherent and systematic correlation with the rest of man's experience. And it can do this successfully only by examining mysticism with as much criticism as sympathy; it should neither take trance-reports at their face value nor dismiss them as being of less importance than ordinary sense reports.
