this human aversion to the unknown or the unexplained, nietzsche warns, may cause people to accept ideas based solely on their emotional appeal rather than on their factual accuracy. when experiencing an event, nietzsche describes, a subject compares this current event to similar events in the past in his or her memory. as a result, the subject develops “causal interpretations,” habits of memory and not an examination of the actual causes of the event in question. this is done, nietzsche believes, because, causes or events that we find in memory are comforting to us because they are familiar. causes that are “new,” “unexperienced,” or “strange,” are not valued because they do not soothe our anxiety over the unknown.
