In contrast to the Master, who remains forever fixed in his humanity as Master, the Slave develops and perfects his humanity, [which was] servile at its origin. He raises himself to [the level of] discursive thought and elaborates the abstract notion of freedom; and he creates himself also as a Citizen who is free and ultimately fully satisfied, by transforming the given World through the Labor that he performs in the Service of the community. It is therefore he [the Slave-Citizen], and not the Master, who is Man properly speaking, the individual who freely creates History. But we must not forget to notice that Service and Labor are free and creative only to the extent that they are accomplished within [or in terms of] the Dread that is born of the consciousness of death. It is therefore, when all is said and done, this consciousness of death that humanizes Man and constitutes the ultimate basis of his humanity.
