Postulating Pain
 
The five postulates in geometry may be paraphrased as a unique straight line can be drawn from any point to any other point. Pain is at the end of a line from where pleasure leaves off. This slave is steel collar locked in the middle of several retaining straight lines perpendicular in the square, center mass retention for optimum position to receive pain and pleasure.

Postulate transitive verb -·lat·ed, -·lat·ing. Archaic to claim; demand; require to assume without proof to be true, real, or necessary, esp. as a basis for argument to take as self-evident or assumed, a basic principle.
