Not long ago, when people set sail to cross oceans, they set off with some charts, a sextant, sight reduction tables, pencils, dividers, parallel rules, a compass, a log to measure knots and a clock. If they knew the speed at which they were sailing, and how long they had sailed, they could determine where they were. They would back that up by taking sights on the stars and the sun and calculating their lat and long.

Man has this propensity to make and change laws. It's a necessity when you have more than 7 billion people trying to occupy this little bit of land mass that is shrinking. I thought things were complicated in the United States of America. Then I moved to Ireland and started to understand what complexity is all about. Millenia of law, altered by invaders and foreign rulers, with precedent upon precedent being reversed, challenged, and rewritten, until no one can tell what's what. Makes it easy to understand how people can evolve into sidestepping behaviors.
