Does this group still work?

Hi, I need help with a 3rd year scociology module, I think I might like to argue that there is me, not me, and something else. If two people can stand in different space and time and then describe what their seeing to someone else and have that person relize what your describing, then there must be something else, as well as me and not me, as this something is a creation. I kind of want to make Descartes math work, what with math bein a construct and that. anybody got any pointers?
