Hans Zinsser Quotes

Throughout the early Christian period, every great calamity - famine, earthquake, and plague - led to mass conversions, another indirect influence by which epidemic diseases contributed to the destruction of classical civilization. Christianity owes a formidable debt to bubonic plague and to smallpox, no less than to earthquake and volcanic eruptions.

Man and rats are merely, so far, the most successful animals of prey. They are utterly destructive of other forms of life. Neither of them is of the slightest use to any other species of living things.

The Archbishop [Thomas Becket] was murdered in Canterbury Cathedral on the evening of the twenty-ninth of December. The body lay in the Cathedral all night, and was prepared for burial on the following day. The Archbishop was dressed in an extraordinary collection of clothes. He had on a large brown mantle; under it, a white surplice; below that, a lamb's-wool coat; then another woolen coat; and a third woolen coat below this; under this, there was the black, cowled robe of the Benedictine Order; under this, a shirt; and next to the body, a curious haircloth, covered with linen. As the body grew cold, the vermin that were living in this multiple covering started to crawl out, and as MacArthur quotes the chronicler: 'The vermin boiled over like water in a simmering cauldron, and the onlookers burst into alternate weeping and laughter.

[I]nfectious disease is merely a disagreeable instance of a widely prevalent tendency of all living creatures to save themselves the bother of building, by their own efforts, the things they require. Whenever they find it possible to take advantage of the constructive labors of others, this is the path of least resistance. The plant does the work with its roots and its green leaves. The cow eats the plant. Man eats both of them; and bacteria (or investment bankers) eat the man ...

We have chosen to write the biography of our disease because we love it platonically - as Amy Lowell loved Keats - and have sought its acquaintance wherever we could find it. And in this growing intimacy we have become increasingly impressed with the influence that this and other infectious diseases, which span - in their protoplasmic continuities - the entire history of mankind, have had upon the fates of men.

But however secure and well-regulated civilized life may become, bacteria, Protozoa, viruses, infected fleas, lice, ticks, mosquitoes, and bedbugs will always lurk in the shadows ready to pounce when neglect, poverty, famine, or war lets down the defenses.

Infectious disease is one of the great tragedies of living things - the struggle for existence between two different forms of life... Incessantly, the pitiless war goes on, without quarter or armistice - a nationalism of species against species.

Our task as we grow older in a rapidly advancing science, is to retain the capacity of joy in discoveries which correct older ideas, and to learn from our pupils as we teach them.

Swords, Lances, arrows, machine guns, and even high explosives have had far less power over the fates of nations than the typhus louse, the plague flea, and the yellow-fever mosquito. Civilizations have retreated from the plasmodium of malaria, and armies have crumbled into rabbles under the onslaught of cholera spirilla, or of dysentery and typhoid bacilli. Huge areas have bee devastated by the trypanosome that travels on the wings of the tsetse fly, and generations have been harassed by the syphilis of a courtier. War and conquest and that herd existence which is an accompaniment of what we call civilization have merely set the stage for these more powerful agents of human tragedy.
