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.

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.

This invisibility, however, means that the opportunities for creative research are infinite.

There is no rational reason to doubt that the universe has existed indefinitely, for an infinite time. It is only myth that attempts to say how the universe came to be, either four thousand or twenty billion years ago.

The experience of democracy is like the experience of life itself-always changing, infinite in its variety, sometimes turbulent and all the more valuable for having been tested by adversity.

Genius is an infinite capacity for taking pains.

Think of something finite molded into the infinite, and you think of man.

There are infinite shadings of light and shadows and colors... it's an extraordinarily subtle language. Figuring out how to speak that language is a lifetime job.

Most human beings have an almost infinite capacity for taking things for granted.

The ultimate creative capacity of the brain may be, for all practical purposes, infinite.

I think if I had been writing fiction, where the work is entirely dependent on the writer's creativity and the potential directions the narrative might take are infinite, I might have frozen.

Only a great actor finds the difficulties of the actor's art infinite.

In the order of literature, as in others, there is no act that is not the coronation of an infinite series of causes and the source of an infinite series of effects.

An infinite God can give all of Himself to each of His children. He does not distribute Himself that each may have a part, but to each one He gives all of Himself as fully as if there were no others.

Younger anthropologists have the notion that anthropology is too diverse. The number of things done under the name of anthropology is just infinite; you can do anything and call it anthropology.

Invention consists in avoiding the constructing of useless contraptions and in constructing the useful combinations which are in infinite minority.

Infinite growth of material consumption in a finite world is an impossibility.

There are writers in Germany who drink the Absolute like water; and there are books in which even the dogs make references to the Infinite.

The Indian Summer of life should be a little sunny and a little sad, like the season, and infinite in wealth and depth of tone, but never hustled.

Our spiritual attitude is determined by our conception of our relation to infinite spirit.

What grieves me most in my past offenses, O my loving God, is not so much the punishment I have deserved, as the displeasure I have given You, Who are worthy of infinite love.

Ideas are infinite, original, and lively divine thoughts.

Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.

The infinite vibratory levels, the dimensions of interconnectedness are without end. There is nothing independent. All beings and things are residents in your awareness.

By mere burial man arrives not at bliss; and in the future life, throughout its whole infinite range, they will seek for happiness as vainly as they sought it here, who seek it in aught else than that which so closely surrounds them here - the Infinite.

Once the realization is accepted that even between the closest human beings infinite distances continue, a wonderful living side by side can grow, if they succeed in loving the distance between them which makes it possible for each to see the other whole against the sky.

There is a concept that is the corrupter and destroyer of all others. I speak not of Evil, whose limited empire is that of ethics; I speak of the infinite.
