ABSTRACT
We cannot define truth in science until we move from fact to law. And within the body of laws in turn, what impresses us as truth is the orderly coherence of the pieces. They fit together like the characters in a great novel, or like the words in a poem. Indeed, we should keep that last analogy by us always. For science is language and, like a language, it defines its parts by the way they make up a meaning. Every word in the sentence has some uncertainty of definition, and yet the sentence defines its own meaning and that of its words conclusively. It is the eternal unity and coherence of science which gives it truth, and which make it a better system of prediction than any less orderly language.
