RAT IN THE SKULL BY ROG PHILLIPS _Some people will be shocked by this story. Others will be deeply moved. Everyone who reads it will be talking about it. Read the first four pages: then put it down if you can._ [Transcriber's Note: This etext was produced from Worlds of If Science Fiction, December 1958.

Indeed, it is safe to say that until the summer of 1955 he was more "normal", better adjusted, than the average college professor. And we have every reason to believe that he remained so, in spite of having stepped out of his chosen field. At the age of thirty-four, he had to his credit a college textbook on advanced calculus, an introductory physics, and seventy-two papers that had appeared in various journals, copies of which were in neat order in a special section of the bookcase in his office at the university, and duplicate copies of which were in equally neat order in his office at home. None of these were in the field of psychology, the field in which he was shortly to become famous--or infamous. But anyone who studies the published writings of Dr. MacNare must inevitably conclude that he was a competent, responsible scientist, and a firm believer in institutional research, research by teams, rather than in private research and go-it-alone secrecy, the course he eventually followed. In fact, there is every reason to believe he followed this course with the greatest of reluctance, aware of its pitfalls, and that he took every precaution that was humanly possible. Certainly, on that day in late August, 1955, at the little cabin on the Russian River, a hundred miles upstate from the university, when Dr. MacNare completed his paper on _An Experimental Approach to the Psychological Phenomena of Verification_, he had no slightest thought of "going it alone." It was mid-afternoon. His wife, Alice, was dozing on the small dock that stretched out into the water, her slim figure tanned a smooth brown that was just a shade lighter than her hair. Their eight-year-old son, Paul, was fifty yards upstream playing with some other boys, their shouts the only sound except for the whisper of rushing water and the sound of wind in the trees. Dr. MacNare, in swim trunks, his lean muscular body hardly tanned at all, emerged from the cabin and came out on the dock. "Wake up, Alice," he said, nudging her with his foot. "You have a husband again." "Well, it's about time," Alice said, turning over on her back and looking up at him, smiling in answer to his happy grin.
