Viv;...All made possible by the air we breathe, is a statement, it is NOT trying to identify the type of spirit as in gods, demons etc, but rather identfies the ancient concept of the physical air which without we would not be able to communicate as we are now doing, with great spirit I might add.
The ancients had many things they called spirit. You are picking thing arbitrarily out of a hat and pretending it's everything. It's a metaphor, picked at random. It gets us no closer to an answer.
Am I right in believing the spirit you are trying to identify is of the supernatural kind? As I have said previously I don't believe there is such a thing.
I wrote the OP, please re-read it you don't understand.
The ability to make higher order abstractions has nothing to do with intellect. I was not insinuating posters are stupid, just not as able as others in this area.
Since you have yet to explain why accepting a non-answer is a good thing and a sign of being able to perform abstract thinking, you really are just telling people they don't have the ability to get it, that they are lacking. Should you be able to connect the dots and demonstrate WHY this answer requires any form of abstract thinking, you may be approaching the state of "having a point" at that time. So far, we have a non-answer your stance that others just don't have the ability to get it.
You'll need to do better than that. Assuming other people aren't capable is a horrible, ignorant and usually wrong starting position.
By saying my comments are off topic, you indicate I have failed in my explanation.
To assist, please read the entire post, since it is easy to extract individual sentences and project them as being off topic when in actuality they are merely smaller parts of a larger whole.
You were asking biology questions. Start a biology thread if that is what you want to discuss.
Here's where it links to the current topic.
The rest of your comment can be summed up as "We don't know." That answer has already been covered.
So far, we are no closer to an answer.
