It is no secret to us, that emotions (and the First System in general) are not opposed to rationality but are instead yet another set of tools to be used, with proper measure of caution, by the aspiring rationalist; like everything. I have long outgrown the "Straw Vulcan" phase, thank you very much.

Also, it's true that there is nothing about any tools in OP. I wrote that, I would know. I'll probably write something about that at some later point. Or not. There's actually a lot of solid material concerning the means of changing one's mind, I just hadn't seen anything specifically about identity and the problems with it.
