Bruno -- As an idealist, I think you have it all backward! I would argue that cardinal numbers are the most 'crisp' entities that we know, and this disqualifies them or being primeval. That is, I think it makes sense to see all developments as beginning relatively vaguely and then becoming more definite over time. So, then, it will have taken these numbers a very long period of evolution (passing through the 'real' stage) to have become as definite as they are now. Or, even if cardinal numbers became quite crisp at the time, say, of the origin of chemistry, that too will have been a long way from primeval.
