another ?

this may sound stupid but I'm not to sure on it.  The race that speaks
this lang. never use I, me, you, him, her, it etc.  they instead use a
term simular to the british use of 'one'  like "One does not think one
should do such a thing." Is this considered 3rd person or not and (heres
the stupid part) should it actually be the number 1.  They do use things
like they and we though so where would this fit in.

Thanks
