Ivan Pavlov
Ivan Pavlov
Ivan Petrovich Pavlov; 26 September 1849 – 27 February 1936) was a Russian physiologist known primarily for his work in classical conditioning. From his childhood days Pavlov demonstrated intellectual brilliance along with an unusual energy which he named "the instinct for research". Inspired by the progressive ideas which D. I. Pisarev, the most eminent of the Russian literary critics of the 1860s, and I. M. Sechenov, the father of Russian physiology, were spreading, Pavlov abandoned his religious career and devoted his life...

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.
Possibilities are like the wings of birds; they allow man to soar and to climb to the heavens. And facts are like the atmosphere against which those wings must beat, and without which the soaring bird will surely plummet back to earth.
But man has still another powerful resource: natural science with its strictly objective methods.
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.
Mankind will possess incalculable advantages and extraordinary control over human behavior when the scientific investigator will be able to subject his fellow men to the same external analysis he would employ for any natural object, and when the human mind will contemplate itself not from within but from without.
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.
Men are apt to be much more influenced by words than by the actual facts of the surrounding reality
Science demands from a man all his life. If you had two lives that would not be enough for you. Be passionate in your work and in your searching.
Precise knowledge of what happens to the food entering the organism must be the subject of ideal physiology, the physiology of the future.
While you are experimenting, do not remain content with the surface of things. Don't become a mere recorder of facts, but try to penetrate the mystery of their origin.
With each meal, when edible substances find their way into the oral cavity, thick and viscous saliva containing much mucus flows out of these glands.
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.
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.
Facts are the air of the scientists. Without them you never can fly.
