He [Paracelsus] was a Swiss, a queer mixture of a man, of keenest intellect and coarsest fiber, an unusual combination. Like most students of these times, he led a wandering life. That was the only way one could keep in touch with what was going on; there were no scientific periodicals, no newspapers and where a postal service existed, it was uncertain and expensive. Consequently, most of the university students, the professors as well, and many physicians wandered from one university to another. Most of these itinerant students were true vagabonds, begging and stealing for their livelihood.
