Karl Popper Quote

The evolution of life on earth, or of human society, is a unique historical process. [From such] a process, we may assume, for example, the laws of mechanics, of chemistry, of heredity and segregation, of natural selection, etc. Its description, however, is not a law but only a singular historical statement.
