In the first one, I understand that Addison is a social reformer and that Addison is criticizing something, but who is trying to change society and is he using writing to change society? From the second I gather that it's Addison who writes, not whoever it is that is trying to change society.

These are simply too complicated. We need more subjects and more finite verbs and fewer gerunds and participles for clear writing.
