The answer to the question, what does it mean to be a person in law, presupposes an answer to the questions, what personhood belongs to a man and what meaning has the legal personality resulting from it. The examination of legal personality is undoubtedly possible from the point of view of positive law.
However, is it possible to know and understand "legal personhood" based on a human individual as a real physical creature? Is possible deduce legal consequences from psychological relation of a man to things, which are, or are not, his property? The answer to those questions could be accurately demonstrated on a human and his relationship to a house he owns and vice versa on a homeless, who has nowhere to stay, however it does not exclude an inception of his psychological relation to things, which does not belong to him.
