Andrei Mirovan I do not see a distinction between cognition and consciousness.
A “mind” suffers the same linguistic error I think. “minding” is an activity but there is no mind without a minding activity.
So I see mind, conscious and cognition as equivalent and interchangeable.
I know that I mind – i cognate – i am being conscious.
I know this takes place while I sleep as my body responds to internal and external stimuli.
An active nervous system or equivalent system connecting extants together is all I think is required for a form of consciousness.
My second message on extended brain is my acknowledgement that this may be a product of the mammal/bird extending body nap to include tool space.
Your car becomes part of your body while you drive for example. You feel the wheels as if they are you.
And when we watch movies we can map ourself upon characters feeling and thinking as we think they do.
So it is possible that I am extending tool space or mapping myself upon other objects or beings.
