This bachelor´s thesis argues for a paradigm shift that emerged as a direct consequence of the gradually developed knowledge regarding the etiology of beriberi.
We are used to the medical and nutritional values of vitamins, we cherish their effectiveness against diseases, or plunge into debates on whether vegans face the risk of running low on B12. What we, however, do not conceive of so much is how the knowledge of vitamins, in the early 20th century, changed the way medical scientists and practitioners theorized disease causation. With the advent of modern microbiology almost every disease was thought to be caused by external agents like bacteria, viruses, or protozoal pathogens. But what if some diseases cannot be explained by such "intrusions"? What if, when, without the "intrusion" of diminutive things the bodily functions will cease? The answer is a gradual transformation of a medical paradigm of disease causation by external factors into a paradigm of internal ones.

Objectives and Topics
This thesis examines the scientific progress and paradigm shift concerning the etiology of the disease beriberi between 1900 and 1920. By conducting a discourse analysis of articles from the medical journal The Lancet, the work traces how the medical perception shifted from external factors to internal nutrient deficiencies, subsequently modeling this transition as an iterative process of cumulative and discontinuous phases.
- Discourse analysis of medical scientific literature from 1900 to 1920.
- Application of Thomas S. Kuhn’s framework of scientific paradigms and revolutions.
- Identification of "observational shifts" in the etiological research of beriberi.
- Development of an iterative model for the synthesis of cumulative and discontinuous scientific progress.
- Critical reflection on the transformation of medical knowledge and terminology.
Excerpt from the Book
2.1 From Positive to Negative Causation
Around 1900, medical researchers and practitioners were committed to a paradigm that predicted external factors for disease causation. Concerning beriberi this paradigm provided two major theories—the germ-theory and the intoxication-theory—which were thought suitable to solve the puzzle of the disease’s etiology. In addition to these theories, the scientific discourse also named dietary and hygienic conditions as plausible factors for beriberi’s origination. Each of these approaches provided plausible arguments that could—at least to some extent—explain the formation of beriberi. This circumstance, however, inhibited a concentration on one single line of investigation and instead produced a myriad of vague explanations.
An article from April 14th 1900, for instance, reveals the role that was given to hygienic factors. It reports an outbreak of beriberi among a crew on a fishing vessel. The crew is said to have lived in “overcrowded” and “ill-ventilated” cabins.7 Moreover, it is noted that the crew should have noticed “a most nauseous smell”8 emanating from the debris the ship carried. On the other hand, a different article proposes the theory of germs. There, the author utters the wish for a bacteriological investigation, for it is “the only scientific guide for action.”9 Or Bullmore, a surgeon to the Falmouth hospital, who, on the contrary, adheres to the intoxication-theory, who proposes the factor of alkaloidal poisoning due to disarranged gastric secretion and suggests an “auto-infection”.10 His article even reflects on further ideas proposed by researchers. For instance, the suggestion for factors such as a “rice insect”11 or the possibility of a microorganism.12 And with the ending of the year, Ronald Ross proposes the possibility (insisting this not to be a theory) of arsenic poisoning due to “tinned and bottled fruits“13 and therefore also assumes beriberi to be a kind of intoxication caused by canned food.

Frequently Asked Questions
What is the primary subject of this thesis?
The thesis investigates the historical scientific progression regarding the etiology of the disease beriberi during the early 20th century, specifically analyzing how the scientific community shifted from external causation theories to the discovery of vitamin deficiency.
What are the central thematic fields addressed in the work?
The work focuses on the philosophy of science, the history of medicine, the transformation of scientific research programs, and the application of Thomas S. Kuhn's theories on paradigm shifts.
What is the main objective of the research?
The goal is to provide a detailed description of the transitional phase of a paradigm shift and to model this progress as a synthesis of cumulative and discontinuous processes.
Which scientific methodology is utilized?
The author employs a discourse analysis of historical articles from the medical journal The Lancet, combined with a term analysis and visual modeling of theoretical changes.
What topics are discussed in the main part of the thesis?
The main sections cover the five identified observational shifts in beriberi research, a detailed visualization of these shifts, and the development of an iterative schema for scientific progress.
Which keywords define this work?
Key terms include paradigm shift, beriberi, scientific progress, vitamin deficiency, observational shifts, and iterative progression.
How does the author interpret "observational shifts"?
Observational shifts refer to specific periods within the revolutionary phase where changes in investigation strategy altered both the perception and theoretical approaches of researchers regarding the cause of beriberi.
What is the significance of the "iterative schema" proposed by the author?
The iterative schema acts as a model to reconcile cumulative and discontinuous processes, explaining how science evolves through theory transformation without requiring new knowledge to emerge ex nihilo.
Does the author claim that the discovery of vitamins was inevitable?
No, the author explicitly states that the development of this knowledge was not inevitable and that different historical paths could have led to different scientific outcomes.
How does the author relate the findings to modern science?
The author notes that while the vitamin-deficiency theory is dominant, the history of beriberi shows that research continues to evolve and that "old" paradigms or factors like intoxication are sometimes revisited in contemporary science.
