| > I could understand one person not quite fathoming the question, but all these people insisting is really odd. If everyone is misunderstanding your question then maybe the problem is with how the question is formed. > This thread doesn't explain the Incas at all Yeah. Nobody is going to explain a whole civilisation with everything involved in a few short sentences. You were asking specificaly how the bridge building knowledge was spread without literacy. That is what was explained to you. Repeatedly. > And then people playing down literacy Nobody is “playing down literacy”. It is just clear from your question that you do not understand how something can happen without it. So I have pointed out examples where skills are transmitted without reading/writing. It is called tacit knowledge and it has a huge role in all kind of skills and technology. > the Middle Ages were fine, secret prehistorical societies had advanced technology, who needs literacy, etc.? What are you talking about? Why are you making things up? > It's just hard to fathom. I can say the same about your weird whatever that list is. |
