Can a word be used incorrectly and still be 'useful'?
I've heard that pragmatists define true statements as those that are useful in predicting future empirical outcomes, to quote Wikipedia.
However, I have heard of words being used incorrectly that can still be 'useful' despite being incorrect. The words 'subjective' and 'objective' are often used in everyday language to divide and distingiush things that are 'a matter of opinion' from things that are 'a matter of fact', respectively. Although this is an oversimplified and incorrect use of the words, you can't deny that people still find them useful in labelling 'facts', as distinguished from 'opinions'. It seems that just because a term is 'useful', doesn't make its usage correct.
What are your thoughts on this? Thanks.
