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.

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.

It is living and ceasing to live that are imaginary solutions. Existence is elsewhere.

But the way people commonly use the word nowadays it means something all of whose parts are mutually interdependent - not only for their mutual action, but for their meaning and for their existence.

The problem with allowing God a role in the history of life is not that science would cease, but rather that scientists would have to acknowledge the existence of something important which is outside the boundaries of natural science.

And, moreover, it is art in its most general and comprehensive form that is here discussed, for the dialogue embraces everything connected with it, from its greatest object, the state, to its least, the embellishment of sensuous existence.

Your paradigm is so intrinsic to your mental process that you are hardly aware of its existence, until you try to communicate with someone with a different paradigm.

I'm not sure how aware of the rest of the world I am. I live a rather sheltered existence.

The more unintelligent a man is, the less mysterious existence seems to him.

She made the decision that her existence had lost its meaning. And you cannot judge that.

Progress is measured by richness and intensity of experience - by a wider and deeper apprehension of the significance and scope of human existence.

Creation destroys as it goes, throws down one tree for the rise of another. But ideal mankind would abolish death, multiply itself million upon million, rear up city upon city, save every parasite alive, until the accumulation of mere existence is swollen to a horror.

Dualists hold that body and soul are separate entities and that the soul will continue beyond the existence of the physical body.

Fix reason firmly in her seat, and call to her tribunal every fact, every opinion. Question with boldness even the existence of a God; because, if there be one, he must more approve of the homage of reason, than that of blindfolded fear.

The police are the public and the public are the police; the police being only members of the public who are paid to give full time attention to duties which are incumbent on every citizen in the interests of community welfare and existence.

In this possibly terminal phase of human existence, democracy and freedom are more than just ideals to be valued - they may be essential to survival.

In the usual progress of things, the necessities of a nation in every stage of its existence will be found at least equal to its resources.

Universities are the cathedrals of the modern age. They shouldn't have to justify their existence by utilitarian criteria.

Behind me the branches of a wasted and sterile existence are cracking.

The best argument I know for an immortal life is the existence of a man who deserves one.

No cause is left but the most ancient of all, the one, in fact, that from the beginning of our history has determined the very existence of politics, the cause of freedom versus tyranny.

Whatever is referred to must exist. Let us call this the axiom of existence.

Now it would be as absurd to deny the existence of God, because we cannot see him, as it would be to deny the existence of the air or wind, because we cannot see it.

As the existence of a corps of professors of mathematics is peculiar to our navy, as well as an apparent, perhaps a real, anomaly, some account of it may be of interest.

Analysis brings no curative powers in its train; it merely makes us conscious of the existence of an evil, which, oddly enough, is consciousness.

A vast abortion industry, generating some half a billion dollars annually, sprang into existence in the wake of Roe and Doe.

Thought is more important than art. To revere art and have no understanding of the process that forces it into existence, is finally not even to understand what art is.
