If Leonardo da Vinci were to go on a speaking tour, what would an evening in his presence entail? Would he pontificate endlessly on the human form, engaging his audience with a PowerPoint of the Vitruvian Man? Or lecture on his musings of tectonic plates, maybe even topographic anatomy? The point is, you would go, because rarely in life does one have the opportunity to sit in the presence of a true polymath, (someone whose breadth of knowledge spans multiple subjects). While Rollins' talking points may come in various forms -- from political diatribe to punk philosophy to spoken word poetry -- these true Renaissance men express intellectual insight that's luminous as the art they create.
