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

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.

Roosevelt's magic lay in one facet of his personality: He knew how to take the risk. No other man in public life I knew could so readily take the challenge of the new.

Man was born free, and he is everywhere in chains.

Photography is a major force in explaining man to man.

The world is... the natural setting of, and field for, all my thoughts and all my explicit perceptions. Truth does not inhabit only the inner man, or more accurately, there is no inner man, man is in the world, and only in the world does he know himself.

I am neither a child, a young man, nor an ancient; nor am I of any caste.

I want the municipality to be a helping hand to the man with a desire of sympathy, to help the fallen when it is not in their power to help themselves.

I always looked for a man to rescue me and bring me happiness. I bought into that myth, of course, and looked for my own Prince Charming.

A desire to be observed, considered, esteemed, praised, beloved, and admired by his fellows is one of the earliest as well as the keenest dispositions discovered in the heart of man.

Nonviolence is a powerful and just weapon. which cuts without wounding and ennobles the man who wields it. It is a sword that heals.

Let me first state that I believe that marriage is a sacred union between one man and one woman.

A man must be strong in that profession, he must have vigor of body and mind, yet I am all out of breath if I walk up a hill; I have not the heart to crush even a fly.

An intelligent man is sometimes forced to be drunk to spend time with his fools.

I believe that if a man does a job as well as a woman, he should be paid as much.

For a man to strike any women is most brutal, and I, as well as everyone else, think this far worse than any attempt to shoot, which, wicked as it is, is at least more comprehensible and more courageous.

There is always a type of man who says he loves his fellow men, and expects to make a living at it.

A man may be in as just possession of truth as of a city, and yet be forced to surrender.

The bravest sight in the world is to see a great man struggling against adversity.

If a man is dumb, someone is going to get the best of him, so why not you? If you don't, you're as dumb as he is.

Happy the man who has been able to learn the causes of things.

Work is not man's punishment. It is his reward and his strength and his pleasure.

'Thou shalt not get found out' is not one of God's commandments; and no man can be saved by trying to keep it.

Sex is the most beautiful thing that can take place between a happily married man and his secretary.

Man has done a lot to make himself dangerous and animals get the worst of all of it. But then, man too is an animal.

A writer may tell me that he thinks man will ultimately become an ostrich. I cannot properly contradict him.

I think I had a more European outlook about the body and sex. The body is in no way dirty, and sex is something beautiful to give to and share with a lover. It has nothing to do with promiscuity, because I only believe in being in love with one man at a time.
