I need to research for a theoretical framework about definition of "person"* by different authors. I'm struggling to find any kind of outline to make the research, so I am wondering if I'm trying to search using a wrong concept. I'm constantly stumbling against "Personal Identity", but is not what I'm looking for. I was thinking that I could research about classical ontological dilemmas like monism vs dualism, but I'm also not quite sure if it will help me into compare definitions.
My first idea was to explain about different epochs, something like: what did greeks philosophers think? in medieval times? in renaissance? in the modern era? in the post modern era? ecc.
* in case is useful to answer the question. I'm asking because we are analyzing a text that speaks about a "person centered approach" in health, so we ask ourselves: ok, what/who is a person then?
