Poison Quotes (34 quotes)

A barbarous practice, the inconsistency, folly, and injury of which no words can sufficiently describe.
Condemning the use of mercurial medicines.
Quoted in Wooster Beach, A Treatise on Anatomy, Physiology, and Health (1848), 177.
Science quotes on:  |  Drug (43)  |  Medicine (344)  |  Mercury (44)

A study of Disease—of Pestilences methodically prepared and deliberately launched upon man and beast—is certainly being pursue in the laboratories of more than one great country. Blight to destroy crops, Anthrax to slay horses and cattle, Plague to poison not armies but whole districts—such are the lines along which military science is remorselessly advancing.

Alcoholism, the opium habit and tobaccoism are a trio of poison habits which have been weighty handicaps to human progress during the last three centuries. In the United States, the subtle spell of opium has been broken by restrictive legislation; the grip of the rum demon has been loosened by the Prohibition Amendment to the Constitution, but the tobacco habit still maintains its strangle-hold and more than one hundred million victims of tobaccoism daily burn incense to the smoke god.
In Tobaccoism: or, How Tobacco Kills (1922), Preface, 7.

All disease, at some period or other of its course, is more or less a reparative process, not necessarily accompanied with suffering: an effort of nature to remedy a process of poisoning or of decay, which has taken place weeks, months, sometimes years beforehand, unnoticed.
In Notes on Nursing: What It Is and What It Is Not (1859), 5.

BELLADONNA, n. In Italian a beautiful lady; in English a deadly poison. A striking example of the essential identity of the two tongues.
The Collected Works of Ambrose Bierce (1911), Vol. 7, The Devil's Dictionary,  36.
Science quotes on:  |  Humour (103)

Carl Sagan quote A Subject Called Chemistry
Wellington College. CC by-NC 2.0 (source)
Chlorine is a deadly poison gas employed on European battlefields in World War I. Sodium is a corrosive metal which burns upon contact with water. Together they make a placid and unpoisonous material, table salt. Why each of these substances has the properties it does is a subject called chemistry.
In Broca's Brain: The Romance of Science (1979), 18, footnote.

During this [book preparation] time attacks have not been wanting—we must always be prepared for them. If they grow out of a scientific soil, they cannot but be useful, by laying bare weak points and stimulating to their correction; but if they proceed from that soil, from which the lilies of innocence and the palms of conciliation should spring up, where, however, nothing but the marsh-trefoil of credulity and the poisonous water-hemlock of calumniation grow, they deserve no attention.
Carl Vogt

Everything is poisonous, nothing is poisonous, it is all a matter of dose.
In Pathologie expérimenta1e (1872), 72. From the original French, “Tout est poison, rien n’est poison, tout est une question de dose.”
Science quotes on:  |  Dose (13)  |  Drug (43)  |  Therapy (12)

Gentlemen and ladies, this is ordinary alcohol, sometimes called ethanol; it is found in all fermented beverages. As you well know, it is considered by many to be poisonous, a belief in which I do not concur. If we subtract from it one CH2-group we arrive at this colorless liquid, which you see in this bottle. It is sometimes called methanol or wood alcohol. It is certainly more toxic than the ethanol we have just seen. Its formula is CH3OH. If, from this, we subtract the CH2-group, we arrive at a third colorless liquid, the final member of this homologous series. This compound is hydrogen hydroxide, best known as water. It is the most poisonous of all.
In Ralph Oesper, The Human Side of Scientists (1975), 189.

He, who for an ordinary cause, resigns the fate of his patient to mercury, is a vile enemy to the sick; and, if he is tolerably popular, will, in one successful season, have paved the way for the business of life, for he has enough to do, ever afterward, to stop the mercurial breach of the constitutions of his dilapidated patients. He has thrown himself in fearful proximity to death, and has now to fight him at arm's length as long as the patient maintains a miserable existence.
Quoted by William M. Scribner, 'Treatment of Pneumonia and Croup, Once More, Etc,' in The Medical World (1885), 3, 187.
Science quotes on:  |  Medicine (344)  |  Mercury (44)

I should regard them [the Elves interested in technical devices] as no more wicked or foolish (but in much the same peril) as Catholics engaged in certain kinds of physical research (e.g. those producing, if only as by-products, poisonous gases and explosives): things not necessarily evil, but which, things being as they are, and the nature and motives of the economic masters who provide all the means for their work being as they are, are pretty certain to serve evil ends. For which they will not necessarily be to blame, even if aware of them.
From Letter draft to Peter Hastings (manager of a Catholic bookshop in Oxford, who wrote about his enthusiasm for Lord of the Rings) (Sep 1954). In Humphrey Carpenter (ed.) assisted by Christopher Tolkien, The Letters of J.R.R. Tolkien (1995, 2014), 190, Letter No. 153.

If you could see what I almost daily see in my practice … persons … in the very last stages of wretched existence, emaciated to a skeleton, with both tables of the skull almost completely perforated in many places, half the nose gone, with rotten jaws, ulerated throats, breaths most pestiferous more intolerable than poisonous upas, limbs racked with the pains of the Inquisition, minds as imbecile as the puling babe, a grievous burden to themselves and a disgusting spectacle to others, you would exclaim as I have often done, 'O! the lamentable want of science that dictates the abuse (use) of that noxious drug calomel!'
[Calomel is the mercury compound, Hg2Cl2.]
Quoted in Wooster Beach, A Treatise on Anatomy, Physiology, and Health (1848), 177.
Science quotes on:  |  Drug (43)  |  Medicine (344)  |  Mercury (44)

If you poison the environment, the environment will poison you.
Science quotes on:  |  Environment (181)

In 1810, the Triumph man-of-war and Phipps schooner received on board several tons of quicksilver, saved from the wreck of a vessel near Cadiz. In consequence of the rolling of the bags the mercury escaped, and the whole of the crews became more or less affected. In the space of three weeks, two hundred men were salivated, two died, and all the animals—cats, dogs, sheep, fowls, a canary bird, nay, even the rats, mice and cockroaches were destroyed.
[The leather bags of mercury had been salvaged and stored without the original wooden cases. Some were stowed in sleeping quarters, and the in same hold as spirit rations.]
The Edinburgh Medical And Surgical Journal, 6. Quoted in Alva Curtis, A Fair Examination and Criticism of All the Medical Systems in Vogue (1855), 38. For more information on the incident, see John Emsley, The Elements of Murder (2006), 38-9.
Science quotes on:  |  Mercury (44)

In fact, almost everything in this isle [Ireland] confers immunity to poison, and I have seen that folk suffering from snake-bite have drunk water in which scrapings from the leaves of books from Ireland had been steeped, and that this remedy checked the spreading poison and reduced the swelling.

Nine-tenths of diseases are medicinal diseases.
[Lamenting the diseases resulting from the continued prescribing of harmful medicinal remedies.]

Only after the last tree has been cut down. Only after the last river has been poisoned. Only after the last fish has been caught. Only then will you find that money cannot be eaten.
Cree Indian prophecy. Quoted by the United Nations Director for the Environment at a conference in Geneva. Recalled by a writer in Ann: Zoologische wetenschappen Issues 275-276 (1984), 16.

Poison should be tried out on a frog.
African proverb, Bantu
Science quotes on:  |  Proverb (24)

Satire is a composition of salt and mercury; and it depends upon the different mixture and preparation of those ingredients, that it comes out a noble medicine, or a rank poison.
In Tryon Edwards (ed.), A Dictionary of Thoughts (1908), 502.

Science is dangerous. There is no question but that poison gas, genetic engineering, and nuclear weapons and power stations are terrifying. It may be that civilization is falling apart and the world we know is coming to an end. In that case, why no turn to religion and look forward to the Day of Judgment, ... [being] lifted into eternal bliss ... [and] watching the scoffers and disbelievers writhe forever in torment.

Technology, when misused, poisons air, soil, water and lives. But a world without technology would be prey to something worse: the impersonal ruthlessness of the natural order, in which the health of a species depends on relentless sacrifice of the weak.
Editorial, 'Nature As Demon', (29 Aug 1986), A26.

The realization of the role played by DNA has had absolutely no consequence for either therapy or prevention…. Treatments for cancer remain today what they were before molecular biology was ever thought of: cut it out, burn it out, or poison it.
From review, 'Billions and Billions of Demons', of the book, The Demon-Haunted World: Science as a Candle in the Dark, by Carl Sagan, in New York Review of Books (9 Jan 1997).

The results of science, in the form of mechanism, poison gas, and the yellow press, bid fair to lead to the total downfall of our civilization.

The vacuum-apparatus requires that its manipulators constantly handle considerable amounts of mercury. Mercury is a strong poison, particularly dangerous because of its liquid form and noticeable volatility even at room temperature. Its poisonous character has been rather lost sight of during the present generation. My co-workers and myself found from personal experience-confirmed on many sides when published—that protracted stay in an atmosphere charged with only 1/100 of the amount of mercury required for its saturation, sufficed to induce chronic mercury poisoning. This first reveals itself as an affection of the nerves, causing headaches, numbness, mental lassitude, depression, and loss of memory; such are very disturbing to one engaged in intellectual occupations.
Hydrides of Boron and Silicon (1933), 203.

Things stand apart so far and differ, that
What’s food for one is poison for another.

Science quotes on:  |  Food (154)

This [cyanide] poison is for professors of chemistry only. You, as a professor of mechanics, will have to use the rope.
Said during the Nazi occupation of Norway.
Quoted in Kaufman, Industrial Chemist and Chemical Manufacturer, Jan 1988.

We starve the rats, creosote the ticks, swat the flies, step on the cockroaches and poison the scales. Yet when these pests appear in human form we go paralytic.

Why Become Extinct? Authors with varying competence have suggested that dinosaurs disappeared because the climate deteriorated (became suddenly or slowly too hot or cold or dry or wet), or that the diet did (with too much food or not enough of such substances as fern oil; from poisons in water or plants or ingested minerals; by bankruptcy of calcium or other necessary elements). Other writers have put the blame on disease, parasites, wars, anatomical or metabolic disorders (slipped vertebral discs, malfunction or imbalance of hormone and endocrine systems, dwindling brain and consequent stupidity, heat sterilization, effects of being warm-blooded in the Mesozoic world), racial old age, evolutionary drift into senescent overspecialization, changes in the pressure or composition of the atmosphere, poison gases, volcanic dust, excessive oxygen from plants, meteorites, comets, gene pool drainage by little mammalian egg-eaters, overkill capacity by predators, fluctuation of gravitational constants, development of psychotic suicidal factors, entropy, cosmic radiation, shift of Earth's rotational poles, floods, continental drift, extraction of the moon from the Pacific Basin, draining of swamp and lake environments, sunspots, God’s will, mountain building, raids by little green hunters in flying saucers, lack of standing room in Noah’s Ark, and palaeoweltschmerz.

[Alchemists] finde out men so covetous of so much happiness, whom they easily perswade that they shall finde greater Riches in Hydargyrie [mercury], than Nature affords in Gold. Such, whom although they have twice or thrice already been deluded, yet they have still a new Device wherewith to deceive um again; there being no greater Madness…. So that the smells of Coles, Sulphur, Dung, Poyson, and Piss, are to them a greater pleasure than the taste of Honey; till their Farms, Goods, and Patrimonies being wasted, and converted into Ashes and Smoak, when they expect the rewards of their Labours, births of Gold, Youth, and Immortality, after all their Time and Expences; at length, old, ragged, famisht, with the continual use of Quicksilver [mercury] paralytick, onely rich in misery, … a laughing-stock to the people: … compell’d to live in the lowest degree of poverty, and … at length compell’d thereto by Penury, they fall to Ill Courses, as Counterfeiting of Money.
In The Vanity of the Arts and Sciences (1530), translation (1676), 313.

[Mercurial medicines] affect the human constitution in a peculiar manner, taking, so to speak, an iron grasp of all its systems, and penetrating even to the bones, by which they not only change the healthy action of its vessels, and general structure, but greatly impair and destroy its energies; so that their abuse is rarely overcome. When the tone of the stomach, intestines, or nervous system generally, has been once injured by this mineral ... it could seldom be restored.
Quoted in Wooster Beach, A Treatise on Anatomy, Physiology, and Health (1848), 177.
Science quotes on:  |  Drug (43)  |  Medicine (344)  |  Mercury (44)

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
