These people are what I refer to as Template-Types or Type-T personalities. These are the people who instinctively or unconsciously compensate for whatever virtues they might lack in themselves. Like any printing template, it is the part that’s missing, its negative space, that shapes and defines their contributions to the world.
The German philosopher Friedrich Nietzsche, being the classic Type-T personality, actually proposed marriage to Lou Salome through his best friend, Paul Rey. Some Ubermensch he was!
