sounds like you're describing Jungs collective unconscious in ways.... Jung claims we are all connected thru stories going all the way back in time... memories and common 'characters' bind us together....

in Cosmic Humanism, we are all interconnected... as in 'my psychology impacts your psychology'...

going one step further... if ppl are spiritual in nature, we are connected thru common stories of God and beliefs... making us a part of the greater whole of all....

describing yourself as one cell is saying you are one organism in the larger body called 'us' which is made up of all the organisms together... a good point of view in my opinion....

it creates a togetherness.. a connectedness.. a brother and sisterhood of man... just what we need in order to effectively voice our selves and be heard as a group, rather than pawns in someone elses game of chess...
