There isn’t exactly right or wrong about the meaning of logistikon, thymoeides, nous etc. Plato doesn’t exactly demonize the feelings, the fear, the anger …(thymoeides), the desires (epithymetikon), etc. These have their virtues, too (their one side of the coin) and what makes the difference is how one uses them. But, above all, the logistikon, the noetic part, is the one that has to be “in charge”, for the other two to be used virtuously, not dragging someone here and there(or “down”). When the logistikon keeps the reins, we are able to react with more clarity in front of any external condition/challenge. Because the target isn’t for parts of self to be killed, but to be lifted up to the level of the Soul. For harmony.
When I use “noetic” or “nous”, I don’t mean just “thinking”, as you have understood. “Thinking” is something that everybody does. And it contains many things; the voice that talks all the time in our head, the voice of anger, the voice of arrogance, the voice that just repeats events again and again, the ability to try to understand the world, etc.
Nous is more than that. You have understood how I see it.
There’s is also subjectivity to matters like this. For example, to you, Roosevelt may have used his thymoeides is a “virtuous” way, but to others, he may haven’t. You see the point. You can catch the point, I know.
I know how you ask, and the words weren’t used in a “wrong” way, though it’s not so much of a language-matter.
You honoured the meanings. And you did it your way, authentically.
