Your Majesties, Your royal highnesses, excellencies, fellow laureates, ladies and gentlemen. I feel honored and furthermore blessed to be standing here today in recognition of my work on the physiology of digestion and I would like to express my deep appreciation to the Nobel committee for awarding me the honour to be here today. Behind every success lies insatiable passion to discover the unknown, which through dedication and hard work can lead to realms beyond ours. Realms of yet discovered truths, realms of the future – a better future.Science has always been my passion despite the fact that five generations in my family been in the clergy, the apple doesn’t fall far from the tree, right? (haha). It is as Laurence Sterne once said, “The desire of knowledge, like the thirst for riches, increases ever with the acquisition of it, “and my desire for knowledge led me to providing the physiological basis for mechanistic, acting out of behaviorism. Please allow me to explain how analyzing the digestive system contributed to understanding the human consciousness and how it’s related to bodily processes. The digestive canal is a complex system. Thousands of vigorous experiments and a long series of chemical laboratories were needed to be done, in order to analyze precisely the amount and quality of gastric secretions to process ingested foods. The experiments focused mainly on the secretory activity of digestion in dogs, by implanting esophageal fistulas food failed to reach the stomach which resulted in producing gastric secretions just like real food did. This led to the rather logical realisation, that the central nervous system was involved in this phenomenon. Many experiments were done to obtain an accurate result. The results occurred to be inaccurate as the dogs varying physical qualities and personality traits influenced these experimental results. To narrow the margin of error and to further simplify upcoming studies, measurements were applied on salivation. Saliva drops and logic combined, were used to understand the inner life of the dog and eventually human being. Thus, creating a conceptual nervous system allowed us to understand and train dogs emotions and personality. Allow me to illustrate this with an example: the phenomenon of «psychic secretion», which is caused by food stimulus at a distance from the animal causes the dog to salivate, which means any other neutral stimulus such as a bell sound associated with the food would also cause the dog to salivate and give a conditioned response and that is when hearing the bell sound, only. The shorter the intervals between repeated stimulations, the weaker the salivary glands grew, until the reaction reached zero, and vice versa. This conditional reflex or rather conditional response is not a phenomenon, it’s merely a method to understand the subjective, emotional and intellectual life of human beings. In hope that these conditional reflexes would be utilized to analyze and treat depression, drug addiction, and a plethora of other mental diseases, to give human beings the capacity to enjoy – what we like to define – a normal life. My speech is reaching its end, and there’s no better way to end it than to, once again, thank you from the bottom of my soul for this great honour which was bestowed upon me, and I hope that my work would help mankind reach a brighter futureThank you.
