_The Evening Post_ (New York) says: "However strong the reader's prejudice * * * * he cannot lay down Prof. Walsh's volume without at least conceding that the author has driven his pen hard and deep into the 'academic superstition' about Papal Opposition to science." In a previous issue it had said: "We venture to prophesy that all who swear by Dr. Andrew D. White's History of the Warfare of Science with Theology in Christendom will find their hands full, if they attempt to answer Dr. James J. Walsh's The Popes and Science." _The Literary Digest_ said: "The book is well worth reading for its extensive learning and the vigor of its style." _The Southern Messenger_ says: "Books like this make it clear that it is ignorance alone that makes people, even supposedly educated people, still cling to the old calumnies." _The Nation_ (New York) says: "The learned Fordham Physician has at command an enormous mass of facts, and he orders them with logic, force and literary ease. Prof. Walsh convicts his opponents of hasty generalizing if not anti-clerical zeal." _The Pittsburg Post_ says: "With the fair attitude of mind and influenced only by the student's desire to procure knowledge, this book becomes at once something to fascinate. On every page authoritative facts confute the stereotyped statement of the purely theological publications." Prof. Welch, of Johns Hopkins, quoting Martial, said: "It is pleasant indeed to drink at the living fountain-heads of knowledge after previously having had only the stagnant pools of second-hand authority." Prof. Piersol, Professor of Anatomy at the University of Pennsylvania, said: "I have been reading the book with the keenest interest, for it indeed presents many subjects in what to me at least is a new light. Every man of science looks to the beacon--truth--as his guiding mark, and every opportunity to replace even time-honored misconceptions by what is really the truth must be welcomed." _The Independent_ (New York) said: "Dr. Walsh's books should be read in connection with attacks upon the Popes in the matter of science by those who want to get both sides."
