“Free of unnecessary ballast, and written with didactical aptitude, this book gives a complete overview of how the different views of scientific progress have developed since the time of the Vienna Circle. It is a suitable introduction to a complex period in contemporary theory of knowledge. In later chapters the author present his own standpoint, so that the work can also be used as a source of new impulses in this direction. …
“The author convincingly works out how from his point of view it is possible to explain the conflict between two theories as an incompatibility of perspectives, and at the same time avoid sliding into relativism by giving criteria for scientific progress. …
