Russell argues that the fundamental building blocks of matter are not atoms or molecules, but rather a more basic and elusive substance called "ultimate constituents." He contends that these constituents are the true fundamental entities that make up everything in the universe, including atoms and molecules. Russell's argument is based on his belief that the concept of ultimate constituents provides a more coherent and comprehensive explanation of the nature of matter than the traditional atomic theory.
