Doubtful Descent of Human Rights from Stoicism
(Section omitted from

If the Stoics contributed to the development of human rights or even natural rights in the modern sense, we would expect this tendency to be expressed in the writings and actions of the Greek and Roman Stoics. There ought to be historical evidence of commitment to something like human rights even if they would not have used our terminology. Let us look in particular in the writings of Roman-era Stoics like Seneca and that Stoic-friendly Skeptic Cicero, who gave positive expression to Stoic ideas in his dialogues.
not permit a thorough discussion of
No things are private by nature but either through long occupancy . . . or through victory [i.e., conquest in war] or by [due process of] law, bargain, purchase, or allotment . . . Whence of [originally common] things [some] became each one’s own, what had fallen to each, each one should retain it.

The Roman-era Stoics did occasionally address the issue of gender equality. Musonius Rufus, a first-century Stoic philosopher whose students left us notes on his discourses, addressed the question of the capacities of women for virtue and philosophy. In his view women’s capacities in this respect are equal to men’s but one should not infer from this that there should be any major change in male and female social roles.
Seneca’s writings on slavery are famous. He discusses the condition of those who are slaves by legal status in a number of places. He argues for kind treatment of such slaves and insists that masters should not act as haughty superiors toward them.
In his essay On Benefits Seneca praises the virtue “humanitas” at some length. This virtue seems to connote kindness or liberality toward the needy and socially vulnerable within one’s sphere of influence and avoidance of cruelty. Yet because ancient and medieval writers commonly distinguish the sphere of justice from that of generosity and gratitude, even if there are analogous features in the corresponding duties, it is unlikely that humanitas can generate a doctrine even of very limited human rights. A virtue related to what modern philosophers would have called imperfect duties, humanitas does not correspond to duties that call for legal enforcement.
In his letters on slavery Seneca stresses that virtually everyone is a slave. His message is the standard Stoic one that all but the rare sage are slaves to external things because of their false judgments about the value of externals. Adopting a metaphor more suggestive of the Platonic tripartite model of the soul than the unitary model of the early Stoics, Seneca suggests that many “free” people are slaves to lust or greed or ambition or fear. He calls for masters to treat slaves kindly to win respect from them. The larger context of the letter shows that Seneca opposes what he considers cruel and inhumane treatment of slaves, but he proposes neither abolition of slavery nor the gradual emancipation of slaves. He knew how much slaves hated their condition and wished to escape it. “In exchange for freedom they pay out the saving which they have scraped together by cheating their own bellies.” But his real aim is to convince his reader to escape from the more serious slavery that derives from not knowing or not practicing the precepts of philosophy: “[Moral] liberty cannot be bought. You must . . . seek [this good] from yourself.”
Elsewhere Seneca addresses the question of slaves’ moral status in a discussion of whether slaves can properly be said to benefit their master. He insists on the humanity of the slave: “He who denies that a slave can sometimes give a benefit to his master is ignorant of the nature of the bond connecting human beings [ius humanum]; for not the [social] status, but the intention, of the one who bestows is what counts. Virtue closes the door to nobody.” Later he explains:
It is a mistake for anyone to believe that the condition of slavery penetrates into the whole being of a man. . . . Only the body is at the mercy and disposition of a master; but the mind is its own master. It is, therefore, the body that Fortune hands over to a master . . . that inner part cannot be delivered into bondage [unless, of course, it delivers itself by judging externals to be truly good or evil—J.G.]. 
This is surely an eloquent passage, but it does not
transcend the standard Stoic teaching about moral freedom. Far more letters are
reliably attributed to Seneca than to
Thus we have seen that although the natural law as the Stoics understood it clearly dictated certain moral attitudes, it did not call for a concerted effort, as modern human rights doctrine does, to promote or defend legal or constitutional standards or to pressure states to modify their policies toward sections of their own population. The absence of such a mandate is reflected in the actual practice of influential Stoics during the Roman imperial era.
The Stoic writers, especially in
the imperial era, were politically
very cautious. That fact did not rule out acts of courage, as when Stoic
philosopher Musonius Rufus tried personally, even if
ineffectively, to prevent armies engaged in a civil war from carrying their
mayhem into the streets of
