What we have forgotten is that thoughts and words are conventions, and that it is fatal to take conventions too seriously. A convention is a social convenience, as, for example, money. Money gets rid of the inconveniences of barter. But it is absurd to take money too seriously, to confuse it with real wealth, because it will do you no good to eat it or wear it for clothing. Money is more or less static, for gold, silver, strong paper, or a bank balance can “stay put” for a long time. But real wealth, such as food, is perishable. Thus a community may possess all the gold in the world, but if it does not farm its crops it will starve. In somewhat the same way, thoughts, ideas, and words are “coins” for real things. They are not those things, and though they represent them, there are many ways in which they do not correspond at all. As with money and wealth, so with thoughts and things: ideas and words are more or less fixed, whereas real things change.
