A quote from the article “Calculus Is Good for You” in Scientific American in 1871 (150 years ago!):

It is admitted by all metaphysicians and educators that the calculus brings into play more faculties of the mind than any other branch of learning. Recognizing this fact, professors should consider their institution a mental gymnasium, which gives the mind exercise that enables it to perform its highest destiny. Herein is the value of solving problems in the calculus, and indeed of all other branches of pure mathematics—that by dealing in abstract ideas, they prepare the mind to apply itself vigorously to profound or complicated subjects connected with the realities of life.”
