本文藉由閱讀《論不平等的起源和基礎》，援引尼采的「系譜」概念所涉及到的起源意義，來解釋盧梭的「起源」藉此凸顯盧梭的「起源」並非一種決定論式解釋。並試圖用傅柯對尼采系譜的解釋一偶然性，反過來去思考盧梭的起源意義，並說明不平等並非一種歷史必然，最後去思考平等的可能。

By reading ＂A discourse on the Origin of Inequality＂ of Rousseau, this article will borrow Nietzsche's concept ＂genealogy＂-following the interpretation of Foucault-to explain that Rousseau's ＂origin＂ is not subject to the deterministic explanation but to the context of accidental occurrence which is the very meaning of the genealogy. After having clarifying the origin in the sense of genealogy, we try to emphasize that Rousseau's inequality is neither based on the logic of identity, nor on the historical necessity. And we have to ask ourselves what the possibility of equality is.
