" For verily thou dost hereby cut thyself off from other work, that is, by thinking what so and so is doing and why, what he is saying, having what in mind, contriving what, and all the many like things such as whirl thee aside from keeping close watch over thine own ruling Reason. "

― Marcus Aurelius , Delphi Complete Works of Marcus Aurelius (Illustrated) (Delphi Ancient Classics Book 37)
