This is reminiscent of the old divide between mathematics and philosophy:

true and useful = math

true and useless = philosophy

What occupation, I wonder, was the person who coined that joke? Compare:

"It is not possible to justify the life of any genuine professional mathematician on the ground of the 'utility' of his work." (G. H. Hardy, 1940)

Which side does the practice of distinguishing between the useful and the useless fall on?

philosophy decides :)

I wouldn't bet on the "true" part in philosophy. More like nonsensical.
