As the subject indicates, I have been thinking about dipping into Seneca lately. I understand that he has written in a wide range of genres (I'd like to stay away from his tragedies for the moment). I also understand that he tends toward a more paratactic style. Are there any of his prose works that are typically recommended as starting-off points for Seneca? Some, maybe, that offer a smooth (easy?) introduction to his style and thought?
Any recommendations would be greatly appreciated.
