The first person he encounters at ingolstadt is krempe, a professor of natural philosophy. this meeting is described as the work of an evil influence ­ the "angel of destruction." the professor is astounded at the absurd and outdated science that victor has read in the past, and tells him to begin his studies completely anew. at first, the narrator is indifferent to the idea of returning to science: he has developed a deep contempt for natural philosophy and its uses. this changes, however, when victor attends a lecture given by a professor named waldman. victor is completely enraptured by the ideas of waldman, who believes that scientists can perform miracles, acquire unlimited powers, and "mock the invisible world with its own shadows." he decides to return to the study of natural philosophy at once; he visits professor waldman the following day to tell him that he has found a disciple in victor frankenstein.
