Premise: Maybe we should ask. So if you're asking me if I feel it's enough or if it's -- I'm not sure what it is you're asking me about that. I feel, actually, that there are topics that probably could be explored in more detail, but I understand that there are limitations within any textbook that you have to hit on core concepts. I believe that core concepts are covered, but I think that, in my opinion, what I've looked at, it's historical context.
Hypothesis: core concepts have been taught by tifa
