Well of course they are, cornelis! One needs the truth to "lie skillfully."
WRT this: "A guy who creates a totally abstract system that bears no close resemblance to the world of actual reality is a guy that is forgotten."
Help me here, for I do not follow: Of whom are you speaking in this remark? Who is it that we are to forget, on your view?
Marx, the guy you said "created a totally abstract system that bore no close resemblance to the world of actual reality." And I said, "Is that so, betty? In truth it bore very great resemblance." And you wanted details, so I said "A guy who creates a totally abstract system that bears no close resemblance to the world of actual reality is a guy that is forgotten" So this isn't about who we are to forget, this is a reply about the details you asked for when I commented on your comment about . . . Marx.
