 We are like the villager with respect to our employment of words and phrases. Knowledge by wont of the use of expressions and of concrete ideas is something everybody learns in the course of growing up speaking and understanding a language: “their ‘logical geography’ is taught by one’s daily walks” (1945, 207). So too do people know how to operate with ordinary, non-technical, and even semi-technical and technical expressions as well as with relatively concrete and some abstract ideas without being able to codify the rules, permissions, or sanctions that govern their operations.
