This chapter reproduces the extant text of the two lectures. In these two lectures, Einstein explains very thoroughly the principles and conceptual foundations of, first, special and then general relativity with a minimum of mathematical apparatus. He also includes qualitative discussions of the main experiential evidence supporting his theories, such as the Michelson-Morley experiment (which Einstein calls the Michelson experiment) as support for the validity of the relativity principle, and also of the propagation of light. The guiding theme is the principle of relativity, which he begins to explain in basic kinematic terms. In the conclusion of both his lectures, he emphasizes, first, that the most important task of a physical theory is to reduce the number of independent assumptions rooted in experience, and that, second, spatial and temporal aspects of reality are inevitably tied up with all other physical laws.
