Learning is distributed and nonlinear

This fits well with the first paragogical principle. Depending on the object of study this is more or less true, i.e. studying accounting is more linear than entrepreneurship. Still though, even if you do enter university knowing you want to study accounting your learning will be distributed and nonlinear. You may take the intro courses and then when you're in advanced tax accounting, realize you did not master exactly how the statement of cash flows works and now you need to go back and re-study, even though you've past the course.

Outside the walls of academia, this holds as well. Consider learning how to play ice hockey. At the beginning its pretty linear, you learn how to skate and handle the puck with your stick. After that? Maybe then you focus all your energy on getting a fantastic shot you could place anywhere you want in the net. Fairly linear, right? But then, it turns out you are too slow to ever get an opportunity to shoot, so you have to go back and learn the finer points about exactly where to put pressure on your blade as you skate for maximum efficiency and speed. Then you get a new coach who gets mad at you for only playing on the offensive end of the ice and not trying in the defensive zone, so you have to learn the proper way to backcheck and cover your opponent the entire length of the ice.

At the end of it all, you may be a complete forward able to score and defend, but you didn't get there in a straight line and the learning was distributed over time.
