Chapter 5 of Chris Gill's Learning to Live Naturally
I'm really enjoying your wonderful series; thank you.
I appreciated your calling out Gill's "brilliant move" to use "motive" instead of "impulse."
To me, "impulse" has always been discordant. That it sends the wrong signal is apparent in the dictionary definition: "a sudden strong and unreflective urge or desire to act." The Stoic conception is anything but "unreflective" or "sudden;" fortunately, "motive" avoids all that, in addition to the other benefits you mention.
