Don't become a mere recorder of facts, but try to penetrate the mystery of their origin.

While you are experimenting, do not remain content with the surface of things.

It is not accidental that all phenomena of human life are dominated by the search for daily bread - the oldest link connecting all living things, man included, with the surrounding nature.

As was to be expected, the discovery of the nervous apparatus of the salivary glands immediately impelled physiologists to seek a similar apparatus in other glands lying deeper in the digestive canal.

Finally, as the digestive canal is a complex system, a series of separate chemical laboratories, I cut the connections between them in order to investigate the course of phenomena in each particular laboratory; thus I resolved the digestive canal into several separate parts.

It has long been known for sure that the sight of tasty food makes a hungry man's mouth water; also lack of appetite has always been regarded as an undesirable phenomenon, from which one might conclude that appetite is essentially linked with the process of digestion.

The gastric laboratory uses its protein ferment under an acid reaction.

Perfect as the wing of a bird may be, it will never enable the bird to fly if unsupported by the air. Facts are the air of science. Without them a man of science can never rise.

Physiology has, at last, gained control over the nerves which stimulate the gastric glands and the pancreas.

Our success was mainly due to the fact that we stimulated the nerves of animals that easily stood on their own feet and were not subjected to any painful stimulus either during or immediately before stimulation of their nerves.

Don't become a mere recorder of facts, but try to penetrate the mystery of their origin.

Our experiments not only proved the existence of a nervous apparatus in the above-mentioned glands, but also disclosed some facts clearly showing the participation of these nerves in normal activity.

Thanks to our present surgical methods in physiology we can demonstrate at any time almost all phenomena of digestion without the loss of even a single drop of blood, without a single scream from the animal undergoing the experiment.

The digestive canal represents a tube passing through the entire organism and communicating with the external world, i.e. as it were the external surface of the body, but turned inwards and thus hidden in the organism.

The physiologist who succeeds in penetrating deeper and deeper into the digestive canal becomes convinced that it consists of a number of chemical laboratories equipped with various mechanical devices.

From the described experiment it is clear that the mere act of eating, the food even not reaching the stomach, determines the stimulation of the gastric glands.

In the case of the stomach, however, the nerves of the glandular cells were always severed when constructing an artificially isolated pouch and this, naturally, affected the normal work of the stomach.

Edible substances evoke the secretion of thick, concentrated saliva. Why? The answer, obviously, is that this enables the mass of food to pass smoothly through the tube leading from the mouth into the stomach.

Only by observing this condition would the results of our work be regarded as fully conclusive and as having elucidated the normal course of the phenomena.

Appetite, craving for food, is a constant and powerful stimulator of the gastric glands.

It is clear to all that the animal organism is a highly complex system consisting of an almost infinite series of parts connected both with one another and, as a total complex, with the surrounding world, with which it is in a state of equilibrium.

It goes without saying that the desire to accomplish the task with more confidence, to avoid wasting time and labour, and to spare our experimental animals as much as possible, made us strictly observe all the precautions taken by surgeons in respect to their patients.

But man has still another powerful resource: natural science with its strictly objective methods.

As we have seen bread and especially dry bread evokes secretion of considerably larger quantities of saliva than meat.

The reporter is the daily prisoner of clocked facts. On all working days, he is expected to do his best in one swift swipe at each story.

As far as I know, only a small minority of mathematicians, even of those with Platonist views, accept the idea that there may be mathematical facts which are true but unknowable.

Facts do not speak for themselves. They speak for or against competing theories. Facts divorced from theories or visions are mere isolated curiosities.

The truth is more important than the facts.

Rude contact with facts chased my visions and dreams quickly away, and in their stead I beheld the horrors, the corruption, the evils and hypocrisy of society, and as I stood among them, a young wife, a great wail of agony went out from my soul.

We don't focus as much in schools on educational knowledge which requires thinking and application, as we do on acquiring facts.

He is indebted to his memory for his jests and to his imagination for his facts.

Facts, according to my ideas, are merely the elements of truths, and not the truths themselves; of all matters there are none so utterly useless by themselves as your mere matters of fact.

The intelligence investigation under the leadership of Senator Church, which I know has helped cause this investigation by you, points out that the agencies did not disclose certain facts to us and that certain plots were going on.

There are no eternal facts, as there are no absolute truths.

Facts can be turned into art if one is artful enough.

Exclusively oral cultures are unencumbered by dead knowledge, dead facts. Libraries, on the other hand, are full of them.

Truth in science is always determined from observational facts.

I have fully cooperated with the investigation and before the grand jury, and I'm quite confident at the end of the day that we'll know what facts are in this particular case.

When it comes to atoms, language can be used only as in poetry. The poet, too, is not nearly so concerned with describing facts as with creating images.

Neither facts nor pictures seem to sink into our centers of feeling any more.

One of the most obvious facts about grown-ups, to a child, is that they have forgotten what it is like to be a child.

I knew the wild riders and the vacant land were about to vanish forever... and the more I considered the subject, the bigger the forever loomed. Without knowing how to do it, I began to record some facts around me, and the more I looked the more the panorama unfolded.

Facts are, insurance ratings are really dependent on the notion that some people are higher risk than others.

To do so, we are creating a Fairness for Switzerland Committee that will not only disseminate some of the facts, but also protect a relationship that is important to all of us in North America.

Entertaining these opinions of the course to be pursued, I beg of gentlemen to look at the question, as I have done, in a calm review of facts and of principles.

In writing biography, fact and fiction shouldn't be mixed. And if they are, the fictional points should be printed in red ink, the facts printed in black ink.

Advocates of unrestricted abortion do not want the public to focus on these undeniable facts of fetal development, but the facts cannot be ignored.

In science, all facts, no matter how trivial or banal, enjoy democratic equality.

One of the most untruthful things possible, you know, is a collection of facts, because they can be made to appear so many different ways.
