Aristotle, a Greek philosopher and student of Plato, emphasized in his work \textit{Politics} that:
"Man is by nature a social animal."
He argued that humans cannot live in isolation and require communities for survival and moral development.
Other philosophers:
(A) Auguste Comte – founder of sociology.
(B) Socrates – focused on ethics and dialogue.
(C) Plato – discussed ideal society and justice.
Hence, Aristotle rightly fits the origin of this quote.
