Just out of curiosity, by extension of your column, would you say that "character determines conduct" or "conduct determines character"
IMHO, I would say that sequentially the identity frame of reference (I) defines the character (cognitive thoughts, values, concepts) which defines and directs emotions (feelings), and conduct (behavior).
"I" feel, "I" think, "I" do, and "I" am. All lead from the central elusive and possibly mythical "I" as a common denominator.
Change them all separately, or just change the "I".
