I always say I can't find what I'm not looking for, which doesn't mean I always know what I'm looking for. And not knowing what I want is unsettling. Recently, I was reminded of the thoughts of French polymath-philosopher René Girard (19232015), who suggested that people are not actually motivated by specific things like lust or capital or power, as major philosophers have declared, but by subtle, disconcerting forces of existential desire for something outside ourselves, never actually knowing what that something is.
Girard explains how this not knowing drives history and invention. His main premise is that we feel desire but, not knowing
what we desire, mimic the desires of others. These "others" we mimic constitute a third element, interrupting the lines of force between a person and the objects desired. This, according to Girard, makes desire, and by extension human evolution, a nebulous but powerful anthropological force engaged in forming human cultures.
In other words, you might like big speakers and fat speaker cables, but maybe only because people around you appear to like them. Same with cars and clothes and lovers.
