Insanity comes in two basic varieties: slow and fast... Viscosity and Velocity are opposites, yet they can look the same. Viscosity causes the stillness of disinclination; velocity causes the stillness of fascination. An observer can't tell if a person is silent and still because inner life has stalled, or because inner life is transfixingly busy.
