The theory of evolution is often disparaged by its opponents as being “just a theory” — i.e., a speculative hypothesis with little basis in hard, scientific fact. But this claim carries with it the implied accusation that Charles Darwin was “just a theorist” — i.e., he was merely an armchair scientist and that his life’s work was nothing more than an exercise in arbitrary speculation. A look at Darwin’s pioneering discoveries, however, reveals the grave injustice of this accusation. Darwin was not “just a theorist” and evolution is not “just a theory.” In this talk, Dr. Keith Lockitch explores Darwin’s life and work, focusing on the steps by which he came to discover and prove the theory of evolution by natural selection.
Amesh Adalja, M.D., discusses the history of vaccination with special attention to the heroic figures who developed this technology. Particular consideration is given to the chain of reasoning leading to the first vaccine, as well as how the germ theory of disease led to a plethora of vaccines that allowed humans to experience a rapid improvement in lifespan and quality of life.
Adalja is a board-certified physician in infectious disease, critical care medicine, emergency medicine and internal medicine, specializing in the intersection of national security with catastrophic health events. He publishes and lectures on bioterrorism, pandemic preparedness and emerging infectious diseases and appears as a guest on national radio and television programs. This talk was delivered on Wednesday, July 6, 2016, at Objectivist Summer Conference 2016 in Bellevue, Washington.
Two fundamentalist Christian churches — Faith Tabernacle Congregation and First Century Gospel Church — were at the heart of the outbreak. Children had not been vaccinated, and when they became ill, their parents prayed instead of taking them to the hospital to receive the intravenous fluids or oxygen that could have saved their lives of those with the worst cases. “If I go to God and ask him to heal my body,” said a church member, Gordon Korn, “I can’t go to a doctor for medicine. You either trust God or you trust man.”
Public health officials turned to the courts to intervene. First, they got a court order to examine the churches’ children in their homes, then to admit children to the hospital for medical care. Finally, they did something that had never been done before or since: They got a court order to vaccinate children against their parents’ will. Children were briefly made wards of the state, vaccinated and returned to their parents. At the time, a religious exemption to vaccination had been on the books in Pennsylvania for about a decade.
To prevent doctors from violating his church’s beliefs against vaccination, the pastor of the Faith Tabernacle Church asked the American Civil Liberties Union to represent him. It refused. “There is certainly a free exercise of religion claim by the parents,” said Deborah Levy, of the Philadelphia chapter of the A.C.L.U., “but there is also a competing claim that parents don’t have the right to martyr their children.”
When spring came and the epidemic faded, C.D.C. officials published the results of their investigation. Over a third of those infected — 486 of 1,424 — belonged to one of those two churches, as did six of the nine dead children.
At the Children’s Hospital of Philadelphia, we saw more than 200 children in our emergency department and admitted about 40. Children would come in, covered in rashes, squinting in the bright light (a side effect caused by eye irritation), struggling to breathe and often extremely dehydrated. It was like being in a war zone. When I asked their parents why they had done what they had done, they all had the same answer: “Jesus was my doctor.”
“In the 4th century BC the Greek philosopher Aristotle traveled to Lesvos, an island in the Aegean teeming, then as now, with wildlife. His fascination with what he found there, and his painstaking study of it, led to the birth of a new science — biology. Professor Armand Leroi follows in Aristotle’s footsteps to discover the creatures, places and ideas that inspired the philosopher in his pioneering work.”
Comments Nick Romeo on Aristotle in an article in The Daily Beast:
Shortly before his death in 1882, Charles Darwin received a letter from a physician and classicist named William Ogle. It contained Ogle’s recent translation of Aristotle’s The Parts of Animals and a brief letter in which he confessed to feeling “some self-importance in thus being a kind of formal introducer of the father of naturalists to his great modern successor.”
Aristotle is not typically remembered as the father of naturalists, but Darwin acknowledged a line of intellectual descent. “I had not the most remote notion of what a wonderful man he was,” Darwin wrote of Aristotle in his reply to Ogle. “Linnaeus and Cuvier have been my two gods, though in very different ways, but they were mere school-boys to old Aristotle.”
A fascinating new book by the evolutionary biologist and science writer Armand Marie Leroi claims that Aristotle fully deserves Darwin’s high praise. In The Lagoon: How Aristotle Invented Science, Leroi argues that Aristotle developed many of the empirical and analytical methods that still define scientific inquiry.
