It is important to stay focused on existence (http://rationalargumentator.com/issue32/focusonexistence.html). It is true that we could use a name to refer to a bacterial infection or to refer to the fever it causes but that distorts our thinking in a subtle way. We may believe we have cured the named condition if the name refers only to the fever and we succeed in brining that down, all the while allowing the unnamed infection continue untreated.

It is worse than the disease analogy in talking of inflation. Prices rise; they do not "inflate." It is the money supply which has actually been increased, inflating it. In using the word "inflation" to describe the price phenomenon, the term is misdirected away from where it actually has explanatory power.
