I'm sorry, when exactly did I say they are in the same class? I'm not a biologist in any way, nor I ever claimed to be one. You could say the same about Harari

I'm sorry, when exactly did I say they are in the same class? I'm not a biologist in any way, nor I ever claimed to be one. You could say the same about Harari in that respect. I am talking about introductions. It's the same story with Lewin. It's nowhere near The Feynman Lectures on Physics but those are simply not something suitable for self-education(which is what OP has clearly stated).
