Okay I got it . But do we have any best possible classification system or map . That is most complete. A map which has tried to capture totality of all known human knowledge without leaving anything significant. I want this so I am not unaware of any field of knowledge. Atleast any significant feild of knowledge Practically Best possible . Thank you sir for your response
