…it is difficult to know how great an edge can be achieved at a particular track until one develops a model for that track and tests it, which requires considerable effort. Should that prove successful, there is still no guarantee that the future will be as profitable as past simulations might indicate. The public may become more skillful, or the dishonesty of the races may increase, or another computer handicapper may start playing at the same time. William Benter, “Computer Based Horse Race Handicapping and Wagering Systems: A Report”
The tyrant has nothing more than the power that you confer upon him to destroy you. Where has he acquired enough eyes to spy upon you, if you do not provide them yourselves? How can he have so many arms to beat you with, if he does not borrow them from you? The feet that trample down your cities, where does he get them if they are not your own? How does he have any power over you except through you? How would he dare assail you if he had no cooperation from you?
