collapse of the old society

Right so this is a different concept to the definition of "duty" you gave previously.

It isn't.

Please explain the difference between both to prove it.

I provided an analogy. Which doesn't contradict anything.

I also already provided the definition of what an analogy is so I could mention it now.

Because your ignorance is very predictable.

I also accurately guessed you'd be backpedaling to saying there's a seperate concept of duty.

And here we are.

Next up - you refusing to explain your own claimed differences between the concepts of duty.

The problem isn't my answer. It's your willful ignorance to understand it.

Simply put:

I asked about duty, not about "biological duty".

Explain how these are different. Otherwise they aren't.
