Ingenuity, knowledge, and organization alter but cannot cancel humanity's vulnerability to invasion by parasitic forms of life. Infectious disease which antedated the emergence of humankind will last as long as humanity itself, and will surely remain, as it has been hitherto, one of the fundamental parameters and determinants of human history.

William Hardy McNeill
Decisive breakthroughs in military medical administration came just after the turn of the twentieth century. Until then, in even the best-managed armies, disease was always a far more lethal factor than enemy action, even during active campaigns.

William Hardy McNeill
The single most important stimulus to my thought came by chance when I took a course from Robert Redfield entitled "Folk Society." …His approach was to set up antithetical ideal types, expecting to locate any actual human community somewhere along the spectrum of opposites his fieldwork had suggested to him.... But in 1936 his typology had no time dimension. I was so strongly attracted to his scheme that it is scarcely an exaggeration to describe my subsequent intellectual effort as an attempt to explore the missing time dimension of social change as Redfield envisaged it, not in Yucatan but around the whole earth and across recorded time.

William Hardy McNeill
Ever since language allowed human cultural evolution to impinge upon age-old processes of biological evolution, humankind has been in a position to upset older balances of nature in quite the same fashion as disease upsets the natural balance within a host's body. Time and again, a temporary approach to stabilization of new relationships occurred as natural limits to the ravages of humankind upon other life forms manifested themselves. Yet, sooner or later, and always within a span of time that remained miniscule in comparison with the standards of biological evolution, humanity discovered new techniques allowing fresh exploitation of hitherto inaccessible forms of life.

William Hardy McNeill
Birth control may in time catch up with death control.... But for the present and the short-range future, it remains obvious that humanity is in course of one of the most massive and extraordinary ecological upheavals the planet has ever known.... a sequence of sharp alterations and abrupt oscillations in existing balances between microparasitism and macroparasitism can therefore be expected in the near future as in the recent past.

William Hardy McNeill
Painting responded to the plague-darkened vision of the human condition provoked by repeated exposure to sudden, inexplicable death. Tuscan painters reacted against Giotto's serenity, preferring sterner, hieratic portrayals of religious scenes and figures. The "Dance of Death" became a common theme for art; and several other macabre motifs entered the European repertory.

William Hardy McNeill
Inferences and large dosages of imagination actually have allowed the construction of a far more adequate understanding of the cosmic and human past than earlier generations achieved. I believe that this is the central intellectual accomplishment of the twentieth century. Innumerable cosmologists, physicists, mathematicians, anthropologists, sociologists, historians, ecologists, ethologists, and other specialists have played their part; a few swashbuckling intellects led the way, and the outlines of an evolutionary worldview, uniting natural and human history, has begun to emerge. It may be convincing for generations to come—or again may not.

William Hardy McNeill
Predictive social science does not exist. Indeed, it seems to me that it cannot ever exist, since the behaviour to be predicted reacts to and is partly shaped by the words used by the predictors.

Religious history also offers another striking parallel between Rome and China. The Buddhist faith began to penetrate the Han empire in the first century A. D., and soon won converts in high places. Its period of official dominance in court circles extended from the third to the ninth centuries A. D. This obviously parallels the successes that came to Christianity in the Roman empire during the same period.

William Hardy McNeill
I came away from the two science surveys superficially acquainted with what was already a rather old-fashioned version of contemporary natural science. Relativity and quantum mechanics were mentioned... but not explained; the stars were still eternal; and both subatomic particles and biochemistry were discreetly omitted.... The two courses persuaded me that, in some sense, I understood the natural world. The illusion endured, for later in life... I tagged along by reading popular accounts, believing that the natural world out there was somehow within my reach, even without the mathematics that made quantum mechanics so mysteriously plausible.

William Hardy McNeill
There is a deep irony in the fact that the more nearly an ideal is brought to realization, the more acutely do the saints and heroes who have committed themselves to the task, experience a vehement sense of failure in not having perfected their ideal in its totality; and inversely, the more perfunctory is the pursuit of an ideal, the less are people troubled by discrepancies between practice and principle.

William Hardy McNeill
So far as I can see, coalescence of faith and truth has not been achieved anywhere in the world, not even in American departments of economics...

William Hardy McNeill
Communication always involves slippage, and intellectual discourse is particularly liable to being twisted since a recipient can only accommodate novelty by fitting it into a preexisting structure of ideas.

William Hardy McNeill
John Dewey's Human Nature and Conduct... What struck me... was the related idea that human thought is a reaction to frustrated habit— what people often do when the outcome of their action disappoints their expectation. I concluded that unthinking, habitual action is the natural and truly happy way of life; whereas thought is a symptom of dysfunction but conducive to survival all the same since, every so often, new thoughts find ways of escaping the frustration that provoked them by inventing satisfying new ways to get things done.

William Hardy McNeill
My principles require me merely to invite you to agree, while expecting the contrary. Missionaries do not make converts with such a message: millions are not mobilized by such tepid phrases. That is why the merely intellectual compulsion to regard human diversity and flux is unlikely to prevail against simpler systems of misunderstanding truly capable of altering the world in which we live.

William Hardy McNeill
The rise of Islam offers perhaps the most impressive example in world history of the power of words to alter human behavior in sudden, surprising ways.

William Hardy McNeill
Positivism... may be regarded as a secularized form of the systematic theology which had been considered the crown of all the sciences in medieval European universities.

William Hardy McNeill
The laws of nature, as analyzed mathematically and descriptively by Ptolemy and Galen, bore an interesting, and perhaps not entirely accidental similarity to the law of nations and of nature, as discerned by a long succession of Roman jurists.... The concept of an objective law applicable to human affairs, yet operating in accord with Nature and Reason and apart both from divine revelation and from human whim or passion, was peculiar to Rome and societies descended from Rome.

William Hardy McNeill
When variations could be so extravagantly successful, displacement of one humanoid population by another even more effective group of hunters must have occurred frequently. Survival was more likely for the more formidable in battle as well as for the more efficient in the hunt.

In 1933-34, I took a full-blown college course on the University of Chicago campus. This was part of an experiment by President Hutchins to see whether combining the last two years of high school with the first two years of college might make a more rigorous curriculum possible for what he called "General Education." This he hoped might provide a rational, philosophical guide to adult life and citizenship, replacing the vanished religious certainties he had grown up to reject—and regret.

Before the eighteenth century the demographic impact of the profession of medicine remained negligible. Relatively few persons could afford to pay a doctor for his often very expensive services; and for every case in which the doctor's attendance really made a difference between life and death, there were other instances in which even the best available professional services made little difference to the course of the disease, or actually hindered recovery.... Only with the eighteenth century did the situation begin to change; and it was not until after 1850 or so that the practice of medicine and the organization of medical services begin to make large-scale differences in human survival rates and population growth.

Social science is itself part of the social experience it seeks to interpret and explain.

William Hardy McNeill
The principle obstacle to human dominion over the rain forests is still the rich variety of parasites lying in wait for intruders.

William Hardy McNeill
The diffusion of alchemy westward, like the movement of astrology eastward, became significant only in the centuries after 200 A. D. The conservatism of learning was such that, even when commercial intercourse had made intellectual contacts possible, little serious interchange took place until severe social stress had disturbed the even tenor of the times in China, India, and Europe. Technology was a little, but only a little, less conservative.

William Hardy McNeill
New diseases like syphilis seemed to call for new and "stronger" medicines; and this became one of the stock arguments for resort to the Paracelsian chemical pharmacopeia and mystical medical philosophy. With every fundamental of medicine thus called into question, the only logical recourse was to observe results of cures administered in accordance with the old Galenic as against the new Paracelsian theories, and then to choose whichever worked better. The swift development of European medical practice to levels of skill exceeding all other civilized traditions resulted.
