coupland's Journal: How High Can a Greater Purpose Go?

Based on what I just typed,

If everything you do must have a greater purpose than the act itself, at what point do you achieve the highest purpose? When do you contact the godhead?

If you don't raise your hand simply to shield your eyes, and a higher purpose is a given, then where does the thought train stop? Assume that everything that follows is an attempt to answer this question but also carries the question "yes but for what purpose?":

  - Raise your arm
  - Cover your eyes
  - Block out the sun
  - Prevent pain
  - Pain is unpleasant
  - Unpleasantness detracts from quality of life
  - Maximizing quality of life is the goal of all humans

I suspect that this is the intellectual equivalent of a kid splashing around in a kiddie pool while others swim laps in the deep end. How high can these questions go and shouldn't every question arrive at the same point? The godhead?
