So whereas Aristotle’s syllogisms depend on four key logical terms – “all”, “some”, “is” and “is not” – Stoic syllogisms have their own set of four key terms: “if”, “and”, “or” and “not”.

“Sporadic cases of plague were discovered throughout the summer and fall of 1900. Most alarming, at least to the native-born American population of San Francisco, was the first white plague victim discovered in August. In January 1901, U.S. Secretary of the Treasury Lyman J. Gage, who oversaw both the Marine Hospital Service and the Immigration Bureau, commissioned three nationally prominent plague experts to investigate the health conditions in San Francisco. Their report, using the best bacteriological methods then available, confirmed that plague did, in fact, visit San Francisco. The experts explained that the wisest precaution to take against plague's potential return was not to isolate people based on race but, instead, to intensify cleansing and fumigation efforts in any area where plague was found. Between March 1, 1900 and February 29, 1904, 121 cases of plague were diagnosed in San Francisco with 113 resulting in death. Of these deaths, 107 were Chinese, 4 were Japanese, and 2 were white.59 Alas, this episode hardly brought an end to the all-too-reflexive impulse Americans often have in establishing quarantine or public health policy based on race, ethnicity, or social disen-franchisement.”

“As the new century began, AIDS researchers pondered this roster of different viral lineages: seven groups of HIV-2 and three groups of HIV-1. The seven groups of HIV-2, distinct as they were from one another, all resembled SIVsm, the virus endemic in sooty mangabeys. (So did the later addition, group H.) The three kinds of HIV-1 all resembled SIVcpz, from chimps. (The eventual fourth kind, group P, is most closely related to SIV from gorillas.) Now here’s the part that, as it percolates into your brain, should cause a shudder: Scientists think that each of those twelve groups (eight of HIV-2, four of HIV-1) reflects an independent instance of cross-species transmission. Twelve spillovers. In other words, HIV hasn’t happened to humanity just once. It has happened at least a dozen times—a dozen that we know of, and probably many more times in earlier history. Therefore it wasn’t a highly improbable event. It wasn’t a singular piece of vastly unlikely bad luck, striking humankind with devastating results—like a comet come knuckleballing across the infinitude of space to smack planet Earth and extinguish the dinosaurs. No. The arrival of HIV in human bloodstreams was, on the contrary, part of a small trend. Due to the nature of our interactions with African primates, it seems to occur pretty often.”

“When reporting on epidemic diseases that primarily struck the poor in Upper Silesia in 1848, the famed German pathologist Rudolf Virchow observed: “it is the curse of humanity that it learns to tolerate even the most horrible situations by habituation, that it forgets the most shameful happenings in the daily shame of events.”82 The toleration of horrible situations that affect only the health of others is a phenomenon, sadly, that is still very much with us.”

“This tense situation exploded early one January morning in 1917 when a group of Mexican women mounted an angry revolt against the immigration officials stationed along the El Paso, Texas–Ciudad Juárez, Mexico, border. They earned their living by day cooking and cleaning in the homes of well-to-do Texans, and each night returned to their homes in Ciudad Juárez. But this particular morning, instead of quietly waiting to cross the border so that they could begin their workdays, the women became enraged over a newly established quarantine against the possible entry of typhus fever. The ironclad measure was established by edict of the surgeon general of the United States. It applied to every Mexican— both immigrants and dayworkers each time they crossed the border into the United States—and included physical examinations, mandatory disinfection of all baggage and personal belongings, and delousing baths with a mixture of kerosene, gasoline, and vinegar. Most intolerable to the Mexicans was the inherent danger of bathing in flammable and noxious agents like gasoline and kerosene. Only nine months earlier, a group of twenty-six Mexicans incarcerated in the El Paso jail underwent a similar disinfection procedure and, soon after a newly arrived prisoner lit a cigarette, were burned to death. While this practice offended and frightened those who were to be subjected to the baths, its dangerous nature seemed to be all but lost on the Americans ordering them.”
