This book analyzes the intricate logical process through which the quantum theory was developed, and shows that the quantum mechanics thus established is governed by stereo-structural logic. The method of analysis is based on Mituo Taketni's three-stage theory of scientific cognition, which was presented and developed in close connection with Yukawa's theory of the meson. According to the three-stage theory, scientific cognition proceeds through a series of coiling turns of the phenomenological, substantialistic and essentialistic stages. The old quantum mechanics is shown to be in a substantialistic stage, followed by the quantum mechanics in the corresponding essentialistic stage.

"... these volumes provide precise chronology and interesting interpretations ... there is much of interest to be found and these chapter-by-chapter guides make Taketani and Nagasaki's work accessible ..."

"The various chapters are preceded by helpful summaries of the main themes to be treated and contain flowchart-like diagrams showing the interconnections between the papers discussed in the text."

“This book is very readable and can be recommended to physicists interested in the history of their science as well as to philosophers and historians.”

“It is as thoroughly written as the first volume and it is fascinating to read in it.”

“This work in three volumes presents the early history of cognition in quantum physics just describing the physical facts, their interpretation and formalization in a very readable form for physicists thereby justifying the realistic philosophical principles adopted by the authors for scientific cognition. It can especially be recommended to lecturers of quantum physics who like to include some history into their lecture.”
