We use the word ‘person’ to signify a particular human being. But it was not always so.
The word person comes from the Latin word persona, maybe from the earlier Etruscan persu, a sort of mask through which actors spoke (per-sonare). Just one or two centuries ago person was still used to signify the exterior appearance of the individual, not the whole being including the human interior.
The word person has subsequently expanded to connote the whole human being, precisely at a time when materialism has been in the ascendant, psychology reduced to an objective science, and inner spiritual/soul experience increasingly denied.
“Once we were human beings, now we are persons.”
Thus language reflects changes in consciousness. Being aware of this helps us to understand how we got where we are, and maybe what has been lost in the process.
This fascinating thread of argument is presented in Anders Lidén’s article ‘Rimbaud and the Breaking Down of the Mask’ in the Jan-Mar 2018 issue of The Beacon magazine.
