  In September 1933 Fleck sent the manuscript of his book Die Analyse einer wissenschaftlichen Tatsache to Moritz Schlick. In March 1934, Schlick replied and expressed his willingness to recommend it for publication under the condition that a specialist on the history of medicine would also review it positively.  In 1935, Benno Schwabe finally published the book Entstehung und Entwicklung einer wissenschaftlichen Tatsache: Einführung in die Lehre vom Denkstil und Denkkollektiv (The Genesis and Development of a Scientific Fact: An Introduction to the Theory of Thought Style and Thought Collective). It was accompanied by a Polish summary of the main theses of the book (1934) and two important papers: “Scientific Observation and Perception in General” (1935b) and “The Problem of Epistemology” (1936). In Poland the book was criticized by Izydora Dąmbska and Fleck answered her critique in (1938). Fleck’s next Polish philosophical article (1939a) referred, among others, to a book by a psychiatrist and historian of medicine, Tadeusz Bilikiewicz.  Bilikiewicz replied with a moderate critique of Fleck’s epistemology. Fleck in turn wrote a paper “Rejoinder to the Comments of Tadeusz Bilikiewicz” (1939b) in which he stated strong anti-realistic theses.
