Are there philosophers who maintain a distinction between what is "true" and what is "useful"? It seems that much of analytical philosophy and higher mathematics is true without being of much use, even to scientists. Scientists and engineers, on the other had, come up with many useful ideas whose truth values may be doubted by the abstract thinkers. In other words, does anyone in philosophy speak of useful untruths or useless truths?
