From Heidelberg he went to Leipzig, then famous for the new studies in psychology which were making the science of the mind almost as exact as that of the body, and became interested in the comparison of race characteristics as influenced by environment, history and language. This probably accounts for the advanced views held by Rizal, who was thoroughly abreast of the new psychology. These ideas were since popularized in America largely through Professor Hugo Munsterberg of Harvard University, who was a fellow-student of Rizal at Heidelberg and also had been at Leipzig. A little later Rizal went to Berlin and there became acquainted with a number of men who had studied the Philippines and knew it as none whom he had ever met previously. Chief among these was Doctor Jagor, the author of the book which ten years before had inspired in him his life purpose of preparing his people for the time when America should come to the Philippines. Then there was Doctor Rudolf Virchow, head of the Anthropological Society and one of the greatest scientists in the world. Virchow was of intensely democratic ideals, he was a statesman as well as a scientist, and the interest of the young student in the history of his country and in everything else which concerned it, and his sincere earnestness, so intelligently directed toward helping his country, made Rizal at once a prime favorite. Under Virchow's sponsorship he became a member of the Berlin Anthropological Society. Rizal lived in the third floor of a corner lodging house not very far from the University; in this room he spent much of his time, putting the finishing touches to what he had previously written of his novel, and there he wrote the latter half of "Noli Me Tangere" The German influence, and absence from the Philippines for so long a time, had modified his early radical views, and the book had now become less an effort to arouse the Spanish sense of justice than a means of education for Filipinos by pointing out their shortcomings. Perhaps a Spanish school history which he had read in Madrid deserves a part of the credit for this changed point of view, since in that the author, treating of Spain's early misfortunes, brings out the fact that misgovernment may be due quite as much to the hypocrisy, servility and undeserving character of the people as it is to the corruption, tyranny and cruelty of the rulers.
