The question(s)

3 minutes after the Big-Bang there was no cognition and at the scale of 10-20 meters there is no cognition...
How did cognition arise, how is it sustained?
How can we specify cognition as a natural phenomenon which is distinct from those that surround it, underlay it and preceed it?
How did the fundamental distinction between subject and object of knowledge appear in the history of nature (where no subject or object as such could be found before)?
