William Hardy McNeill Quotes

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.

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.

The Chinese language lacked terms capable of conveying Buddhist meanings; and not until the fifth century did a handful of scholars become sufficiently at home in both Chinese and Indian learning to be able to translate Buddhist texts into Chinese with a modicum of adequacy. ...the novel and initially alien outlook of the Indian faith had somehow to come to terms with the various strands already woven into Chinese culture, ranging... from Confucian and Taoist learning to local sub-literate peasant magic. ...while accommodating themselves to older Chinese expectations, Buddhist doctrines and practices simultaneously widened and redefined traditional Chinese sensibilities and aspirations.

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.

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.

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.

There was a Christian redaction of the historical vision of reality, associated especially with the thought of St. Augustine of Hippo.

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.

Christian theology was a revised version of Greek philosophy and the effort Plato and his heirs made to discern the permanent behind the sensible, the Ideal and the Real behind the world of individual things — ever in flux, becoming and decaying and never, ever reliably and completely True.

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.

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.

I am old enough to remember well the depression years of the middle 1930s, when economists were quite unable to agree on what public policy should be, and when President Hoover, in need of advice, turned by preference to sociologists to study and illuminate recent social trends. The circumstances of the 1980s seem similar; perhaps contemporary confusions and dismay will mark the dethronement of economics from its privileged place among the social sciences — but perhaps not.

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.

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.

Ssu-ma Ch'ien's many-volumed history of China established the frame within which Chinese history continued to be written almost to the present day. Ssu-ma Ch'ien accepted and made canonical the theory that each dynasty began with an especially virtuous ruler and then gradually dissipated that virtue until Heaven lost patience and substituted a new dynasty in its place.
