To amplify on this one:
4 - Bodies also have "qualities" which can and do change without changing their essence, which include slavery, poverty, riches, war, peace, rest, motion. (See Loeb / Hicks edition of DIogenes Laertius, page 600.)
Are in fact rest, motion, and TIME properly considered to be Qualities / Events? I think so based on what I am reading. I point this out because it seems to me it is one thing to consider bondage/liberty/riches/poverty etc to be "qualities" but to consider "time" and "motion" and "rest" to be qualities stretches our normal use of the word "quality."
"Event" seems a much more appropriate word for time and motion and rest than "quality" or "accident," and that's likely another argument for using the term "Event" to describe this category.
