[A vitamin is] a substance you get sick from if you don't eat it.

[For] those suffering under the thraldom of the vice [of opium eating] … it is well to avoid undue harshness with the patient; and it should be carefully remembered, that in many instances the sufferers are more objects of pity than of blame.

[In] death at least there would be one profit; it would no longer be necessary to eat, to drink, to pay taxes, or to [offend] others; and as a man lies in his grave not one year, but hundreds and thousands of years, the profit was enormous. The life of man was, in short, a loss, and only his death a profit.

'[R]eductionism' is one of those things, like sin, that is only mentioned by people who are against it. To call oneself a reductionist will sound, in some circles, a bit like admitting to eating babies. But, just as nobody actually eats babies, so nobody is really a reductionist in any sense worth being against.

[When questioned on his longevity] First of all, I selected my ancestors very wisely. ... They were long-lived, healthy people. Then, as a chemist, I know how to eat, how to exercise, keep my blood circulating. ... I don't worry. I don't get angry at people. I don't worry about things I can't help. I do what I can to make the world a better place to live, but I don't complain if things aren't right. As a scientist I take the world as I find it.
[About celebrating his 77th birthday by swimming a half mile in 22 minutes] I used swim fins and webbed gloves because a man of intelligence should apply his power efficiently, not just churn the water.

Question: Why do the inhabitants of cold climates eat fat? How would you find experimentally the relative quantities of heat given off when equal weights of sulphur, phosphorus, and carbon are thoroughly burned?
Answer: An inhabitant of cold climates (called Frigid Zoans) eats fat principally because he can't get no lean, also because he wants to rise is temperature. But if equal weights of sulphur phosphorus and carbon are burned in his neighbourhood he will give off eating quite so much. The relative quantities of eat given off will depend upon how much sulphur etc. is burnt and how near it is burned to him. If I knew these facts it would be an easy sum to find the answer.

SIR TOBY: Does not our lives consist of the four elements?
SIR ANDREW: Faith, so they say; but I think it rather consists of eating and drinking.
SIR TOBY: Thou'rt a scholar; let us therefore eat and drink.

A nuclear power plant is infinitely safer than eating, because 300 people choke to death on food every year. (1977)

A work of genius is something like the pie in the nursery song, in which the four and twenty blackbirds are baked. When the pie is opened, the birds begin to sing. Hereupon three fourths of the company run away in a fright; and then after a time, feeling ashamed, they would fain excuse themselves by declaring, the pie stank so, they could not sit near it. Those who stay behind, the men of taste and epicures, say one to another, We came here to eat. What business have birds, after they have been baked, to be alive and singing? This will never do. We must put a stop to so dangerous an innovation: for who will send a pie to an oven, if the birds come to life there? We must stand up to defend the rights of all the ovens in England. Let us have dead birds..dead birds for our money. So each sticks his fork into a bird, and hacks and mangles it a while, and then holds it up and cries, Who will dare assert that there is any music in this bird’s song?

After eating, do amphibians need to wait an hour before getting OUT of the water?

After the German occupation of Holland in May 1940, the [last] two dark years of the war I spent hiding indoors from the Nazis, eating tulip bulbs to fill the stomach and reading Kramers' book “Quantum Theorie des Elektrons und der Strahlung” by the light of a storm lamp.

All that would be required to prevent the disease [cholera] would be such a close attention to cleanliness in cooking and eating, and to drainage and water supply, as is desirable at all times.

Animals, even plants, lie to each other all the time, and we could restrict the research to them, putting off the real truth about ourselves for the several centuries we need to catch our breath. What is it that enables certain flowers to resemble nubile insects, or opossums to play dead, or female fireflies to change the code of their flashes in order to attract, and then eat, males of a different species?

As was the case for Nobel's own invention of dynamite, the uses that are made of increased knowledge can serve both beneficial and potentially harmful ends. Increased knowledge clearly implies increased responsibility. We reject the notion advocated in some quarters that man should stop eating from the tree of knowledge, as if that were humanly possible.

Be temperate in wine, in eating, girls, & sloth;
Or the Gout will seize you and plague you both.

Cheese and salt meat, should be sparingly eat.

Eat to live, and not live to eat.

Eating the Honey of Words.

Eating too much kills more quickly than eating too little.

Even when all is known, the care of a man is not yet complete, because eating alone will not keep a man well; he must also take exercise. For food and exercise, while possessing opposite qualities, yet work together to produce health.

For the evolution of science by societies the main requisite is the perfect freedom of communication between each member and anyone of the others who may act as a reagent.
The gaseous condition is exemplified in the soiree, where the members rush about confusedly, and the only communication is during a collision, which in some instances may be prolonged by button-holing.
The opposite condition, the crystalline, is shown in the lecture, where the members sit in rows, while science flows in an uninterrupted stream from a source which we take as the origin. This is radiation of science. Conduction takes place along the series of members seated round a dinner table, and fixed there for several hours, with flowers in the middle to prevent any cross currents.
The condition most favourable to life is an intermediate plastic or colloidal condition, where the order of business is (1) Greetings and confused talk; (2) A short communication from one who has something to say and to show; (3) Remarks on the communication addressed to the Chair, introducing matters irrelevant to the communication but interesting to the members; (4) This lets each member see who is interested in his special hobby, and who is likely to help him; and leads to (5) Confused conversation and examination of objects on the table.
I have not indicated how this programme is to be combined with eating.

Geology is part of that remarkable dynamic process of the human mind which is generally called science and to which man is driven by an inquisitive urge. By noticing relationships in the results of his observations, he attempts to order and to explain the infinite variety of phenomena that at first sight may appear to be chaotic. In the history of civilization this type of progressive scientist has been characterized by Prometheus stealing the heavenly fire, by Adam eating from the tree of knowledge, by the Faustian ache for wisdom.

He who plants a Walnut-Tree, expects not to eat of the fruit.

I have no doubt that it is a part of the destiny of the human race, in its gradual improvement, to leave off eating animals, as surely as the savage tribes have left off eating each other, when they came in contact with the more civilised.

In Japan, an exceptional dexterity that comes from eating with chopsticks … is especially useful in micro-assembly. (This … brings smiles from my colleagues, but I stand by it. Much of modern assembly is fine tweezer work, and nothing prepares for it better than eating with chopsticks from early childhood.)

In not a few the [opium-eating] habit has crept upon them almost unconsciously, during the medicinal use of opiates to soothe pain, to remove sleeplessness, or to arrest protracted bowel-complaint. The risk of this evil should therefore be carefully borne in mind, for life-long misery has often been caused by undue laxity in the prescribing of opiates.

It is a fair question whether the results of these things have induced among us in a large class of well-to-do people, with little muscular activity, a habit of excessive eating [particularly fats and sweets] and may be responsible for great damage to health, to say nothing of the purse.

Just as eating contrary to the inclination is injurious to the health, so study without desire sports the memory, and it retains nothing that it takes in.

Man is an eating animal, a drinking animal, and a sleeping animal, and one placed in a material world, which alone furnishes all the human animal can desire. He is gifted besides with knowing faculties, practically to explore and to apply the resources of this world to his use. These are realities. All else is nothing; conscience and sentiment are mere figments of the imagination. Man has but five gates of knowledge, the five senses; he can know nothing but through them; all else is a vain fancy, and as for the being of a God, the existence of a soul, or a world to come, who can know anything about them? Depend upon it, my dear madam, these are only the bugbears by which men of sense govern fools.

Mathematics is of two kinds, Rigorous and Physical. The former is Narrow: the latter Bold and Broad. To have to stop to formulate rigorous demonstrations would put a stop to most physico-mathematical inquiries. Am I to refuse to eat because I do not fully understand the mechanism of digestion?

Meat-eating has not, to my knowledge, been recorded from other parts of the chimpanzee’s range in Africa, although if it is assumed that human infants are in fact taken for food, the report that five babies were carried off in West Africa suggests that carnivorous behavior may be widespread.

Our ability to think is the one survival tool we have. Science is applied thought. Without science, we’re living in caves and eating cockroaches.

Sarcophagus is a stone that devours dead bodies, for in Greek σάρκος means “flesh” and φαγώ “eating”. Some of the ancients first made coffins for the dead of this stone because in the space of thirty days it consumed the dead… . For this reason stone monuments are called sarcophagi.

The chief pleasure [in eating] does not consist in costly seasoning, or exquisite flavor, but in yourself.

The custom of eating the lover after consummation of the nuptials, of making a meal of the exhausted pigmy, who is henceforth good for nothing, is not so difficult to understand, since insects can hardly be accused of sentimentality; but to devour him during the act surpasses anything the most morbid mind could imagine. I have seen the thing with my own eyes, and I have not yet recovered from my surprise.

The human species was born when one isolated group of bipedal apes got itself stuck and then speciated to get better survival value out of eating meat.

The way a child discovers the world constantly replicates the way science began. You start to notice what’s around you, and you get very curious about how things work. How things interrelate. It’s as simple as seeing a bug that intrigues you. You want to know where it goes at night; who its friends are; what it eats.

There was a golden period that I look back upon with great regret, in which the cheapest of experimental animals were medical students. Graduate students were even better. In the old days, if you offered a graduate student a thiamine-deficient diet, he gladly went on it, for that was the only way he could eat. Science is getting to be more and more difficult.

These turdy-facy-nasty-paty-lousy-fartical rogues, with one poor groat's worth of unprepared antimony, finely wrapt up in several scartoccios, are able, very well, to kill their twenty a week, and play; yet, these meagre, started spirits, who have half stopt the organs of their minds with earthy oppilations, want not their favorers among your shrivell’d sallad-eating artizans, who are overjoyed that they may have their half-pe’rth of physic; though it purge them into another world, it makes no matter.

This discovery, indeed, is almost of that kind which I call serendipity, a very expressive word, which as I have nothing better to tell you, I shall endeavour to explain to you: you will understand it better by the derivation than by the definition. I once read a silly fairy tale, called The Three Princes of Serendip: as their highnesses travelled, they were always making discoveries, by accidents and sagacity, of things which they were not in quest of: for instance, one of them discovered that a mule blind of the right eye had travelled the same road lately, because the grass was eaten only on the left side, where it was worse than on the right—now do you understand serendipity?

Timorous readers, however, need entertain no feverish fear, on, visiting the Isle of Sheppey, of encountering either wild elephants, crocodiles, sharks, serpents, or man-eating birds of huge dimensions, bearing strange names, and armed with sets of teeth for masticating and digestive purposes, as the author can assure them that they all died out a million or so of years ago, before he undertook to look up their records and write the history of this wonderful little island. Visitors may, however, honestly deplore the absence of the feathery palm trees bearing the luscious date and the lacteous cocoa-nut; but by prosecuting a diligent search they may, at least, be consoled by procuring some of these, rare fossil remains, reminiscent of an incalculable period of time when our particular portion of this hemisphere performed its diurnal revolutions in the immediate zone of the tropics.

We are all dietetic sinners; only a small percent of what we eat nourishes us, the balance goes to waste and loss of energy .

What can you conceive more silly and extravagant than to suppose a man racking his brains, and studying night and day how to fly? ... wearying himself with climbing upon every ascent, ... bruising himself with continual falls, and at last breaking his neck? And all this, from an imagination that it would be glorious to have the eyes of people looking up at him, and mighty happy to eat, and drink, and sleep, at the top of the highest trees in the kingdom.

What would life be without art? Science prolongs life. To consist of what—eating, drinking, and sleeping? What is the good of living longer if it is only a matter of satisfying the requirements that sustain life? All this is nothing without the charm of art.

When you think about flying, it’s nuts really. Here you are at about 40,000 feet, screaming along at 700 miles an hour and you’re sitting there drinking Diet Pepsi and eating peanuts. It just doesn’t make any sense.

You ask me how, with so much study, I manage to retene my health. ... Morpheous is my last companion ; without 8 or 9 hours of him yr correspondent is not worth one scavenger's peruke. My practices did at ye first hurt my stomach, but now I eat heartily enou' as y’ will see when I come down beside you. [On the value of sleep, and harm of eating poorly while intent on study.]
