"The part and the whole" is the most peculiar book of Werner Heisenberg. As a matter of fact, it is the autobiography of the author but everything revoles arout different problems of atomic theory, divided into 20 chapters. In each of them the author tried to touch a certain topic. Great attention is paid to philosophical problems risen by quantum theory. Here is one of the main merits of the book. Fact is that quantum theory put before its creators philosophical problems that were not imagined and forced to revise not only physical but also philosophical standpoints that were elaborated during centuries.
