When most people close their eyes and imagine a motorcycle, that motorcycle looks very much like a Harley-Davidson. That's because Harley builds the archetypal motorcycle, the mythic bike that exists beyond the input provided by our traditional senses. This is what the philosopher Kant called a priori knowledge, knowledge we can't learn but only intuit. That makes a Harley-Davidson the a priori motorcycle. The Harley-Davidson Motor Co. builds motorcycles that look the way the primordial biker inside each of us feels a motorcycle should be built. This is why Harley-Davidson defines the very word motorcycle for so many people.
