You are right Godfrey - I will take the blame for messing this up. PD22 clearly belongs with 23-25.
Why don't we plan to focus on 21 and consider the many ramifications of that one, especially the "no need of actions which involve competition."
I think there are varying translations of "competition" and we can also use this to continue to sort out the issue of how much "ambition" is appropriate in the pursuit of pleasure.
