The Author is of the opinion that cultural impact of modern theoretical physics is entirely negative. This is so because modern theoretical physics does not have a consistent view of the world. This is to be compared with the blessing of having a consistent and understandable view of the world, as given, for example, by the mediaeval astronomy and theology.
The subject of considerations in this work are Einstein's and Dirac's views on theoretical physics. Using as an example the Euclidean geometry and its epistemological status through the ages, the author outlines the basic philosophy of the modern theoretical physics, emphasising in particular the prominent role of ideas of simplicity and beauty as the guiding principles of research in theoretical physics.
