=Socialism and Modern Thought.= This is planned for the third volume of the series, and will probably be ready in the summer or fall of 1908. It will be a direct supplement to this present volume, =Evolution, Social and Organic=, which explains the scientific basis on which socialism rests. The second volume, as we have shown, is taken up with an examination of rival theories. The third volume will restate the principles of socialism and show how they are applied to the pressing problems of today. A lecture on “The Economic Interpretation of History” will show how Marx’s historical method throws a search-light on the darkest places in which sociological students have hitherto groped. One on “The Positive School of Criminology” will tell how the socialist scholars of Italy have revolutionized the once hopeless science of crimes and punishments, and have established certain very definite and very fruitful propositions, showing all the while that crime must last while capitalism lasts. In “The Latest Word of Science and Philosophy--Monism,” Mr. Lewis will show how the clearest thinkers in the modern socialist movement have arrived at a conception of the universe that is broad enough to take in all reality, and to show the relation of the facts of mind to the facts of matter. We have room to mention here but one more lecture, and that shall be “The Inevitability of the Triumph of Socialism.” Each of these volumes will be uniform with the present one; advance orders are solicited. The price, postage included, will be fifty cents each. =The Art of Lecturing.= Mr. Lewis had persistently been urged to teach a class in the art of lecturing, but the many demands on his time made this quite out of the question, and as the best way to satisfy his friends, he wrote a series of brief articles for the Chicago Daily Socialist, each article containing some practical suggestions for young socialist speakers, each suggestion the direct fruit of the author’s personal experience. These articles at once attracted wide attention, and long before they had all appeared, there was an unmistakable demand for their publication in book form. That is why this book is issued. There is nothing else quite so helpful for the young man or woman who expects to lecture on the socialist platform. And many others who have no thought of lecturing will enjoy reading the book, because it brings the reader into such close touch with the personality of a man worth knowing. Paper, 25c, postpaid.
