Though dogged in his desire to confirm this "pseudoscientific" (plain false tbh) model of the solar system, #Kepler also stuck to the data and thus ended up elaborating three robust laws of planetary motion which paved a significant part of the way towards Newton's later laws.
If I've understood the now (imo) become distasteful dispute between #IIT advocates and critics, then I believe this historical example contains important lessons for both.
