Just a thought.
@modern-prometheus: Of course, philosophers influence a wide variety of people. I was just trying to emphasize the intertwined roles of the artists and philosophers. Artists tend to have roles that make ordinary people understand (philosophical) things that are not normally within the realm of their discourse. There have been many instances in history where art and philosophy are intertwined; one good example I think would be the Greeks. Philosophers also tend to create their roles wherein they reflect about the present state of humanity, its society etc. In turn, their philosophical ramblings would be the source of inspiration for many budding artists, and it just goes on and on.
