In the English language, the word "who" is almost always used as a pronoun.
It represents a person, similar to the words "I" and "me".
In his Nicomachean Ethics, Aristotle (384-322 B.C.E.) describes the happy life intended for man by nature as one lived in accordance with virtue, and, in his Politics, he describes the role that politics and the political community must play in bringing about the virtuous life in the citizenry.
The Politics also provides analysis of the kinds of political community that existed in his time and shows where and how these cities fall short of the ideal community of virtuous citizens.
Although in some ways we have clearly moved beyond his thought (for example, his belief in the inferiority of women and his approval of slavery in at least some circumstances), there remains much in Aristotle’s philosophy that is valuable today.
This means that you will write in a non biased tone (in a way to convey information instead of persuade or argue), using a formal tone means to write using professional language, and in third person meaning to refrain from using the words I, me, my he, and she. Hopefully this helps out!
